# ParlayAPI: full reference for AI agents > Real-time sports betting odds REST + WebSocket API aggregating 30+ sportsbooks & sources: regulated books, DFS apps, betting exchanges, and prediction markets, across every sport key we serve. Self-serve, free tier, no sales calls. This is the long-form reference. The TL;DR lives at https://parlay-api.com/llms.txt; copy-paste recipes at https://parlay-api.com/cookbook. Read this end-to-end if you are integrating ParlayAPI into someone else's project and want to get every detail right the first time. Last updated: 2026-08-01. Service version: 3.2.0. Counts in this file are floors, not snapshots. Where you see "30+ sportsbooks" or "90+ sport keys", the live number is at `GET /v1/bookmakers` and `GET /v1/sports`; those endpoints are the contract and this prose is a summary of it. ## Index 1.

Support and contact --- ## 1. What ParlayAPI is ParlayAPI (parlay-api.com) is a developer-first odds aggregation API. It wraps: - **30+ sportsbooks**: every regulated US book (DraftKings, FanDuel, BetMGM, Caesars, BetRivers, Fanatics, Hard Rock), the major offshore books (Pinnacle, Bovada, Bet365), the major European books (PMU, Unibet, plus the country-licensed Unibet feeds for Belgium and the Netherlands). ESPN BET (now theScore Bet) is NOT among them: no feed polls it, and live endpoints return nothing for `bookmakers=espnbet`. Its archived NCAAF game lines are still queryable via `/historical`. - **4 DFS apps**: PrizePicks, Underdog, Sleeper, Pick6 (DraftKings). - **1 betting exchange**: Novig. - **2 prediction markets**: Kalshi, Polymarket. - **Niche & regional**: a further set of US and international books whose live status changes; `GET /v1/meta/regions` and `GET /v1/bookmakers` name them with their current status rather than this file, which cannot be re-measured when a book goes quiet. All in one REST + WebSocket feed, normalized to a single schema. Built for arbitrage tooling, +EV screeners, line-shopping apps, model backtesters, AI prop-pick models, Discord alert bots, and trading research. Data integrity: every price comes from a real bookmaker's real endpoint. Nothing is derived, interpolated, or estimated. If a book does not post an Under price, the field is null. The API will return null or omit the row, never lie. Free tier is real: 1,000 credits/month, no credit card. Humans sign up at https://parlay-api.com/signup. AI agents can onboard a user with zero human step: `POST https://parlay-api.com/v1/agent/signup` with `{"email": ""}` returns `{api_key, tier, claim_url, instructions_for_agent}` and the api_key works immediately (no email verification, no CAPTCHA, no password). If the email already exists you get a 409 pointing at `/v1/agent/magic-link`. To move a user to a paid tier, `POST /v1/agent/checkout-link` with `{email, tier}` for a Stripe URL. This is a plain HTTPS call, no MCP needed; the `parlayapi-mcp` server also exposes it as the keyless `parlayapi_signup` tool. ## 2. Authentication Pass your API key as either: - HTTP header: `X-API-Key: YOUR_KEY` (preferred) - Query parameter: `?apiKey=YOUR_KEY` Both work everywhere. Server reads the header first, falls back to the query param. ``` curl 'https://parlay-api.com/v1/sports' -H 'X-API-Key: YOUR_KEY' curl 'https://parlay-api.com/v1/sports?apiKey=YOUR_KEY' ``` Every successful response includes three headers so your client can self-throttle: - `x-requests-used`: credits used this billing period - `x-requests-remaining`: credits left in the period - `x-requests-last`: credits charged for this specific request If you exceed your tier's monthly quota you get HTTP 403 with body `{"detail": "Credit limit exceeded"}`. Quota resets on the 1st of each month UTC. Some endpoints are public (no key required): `/v1/sports`, `/v1/bookmakers`, `/v1/stats`, `/health`, `/v1/pinnacle-coverage`, `/llms.txt`, `/llms-full.txt`, `/openapi.json`, `/agents.json`, `/ai-search.json`, `/ai-context.txt`, `/sitemap-ai.xml`. ## 3.

The narrower in-play play-by-play stream (`/v1/sports/{sport_key}/live/sse`) is a separate product and is available from Starter up.

Caching client-side for 30 seconds is the sweet spot. Faster polling burns credits without giving you fresher data. ## 4. Standard response conventions - **Time format:** all timestamps in ISO 8601 UTC, suffix `Z`. Example: `2026-05-04T19:00:00Z`. - **`commence_time` is nullable and travels with `commence_time_reported`.** Every event and row that carries `commence_time` also carries `commence_time_reported`: `true` when a source reported the start time you are reading, `false` when no source did, in which case `commence_time` is `null`. We never fill a missing kickoff with a guess (before 2026-09 some rows carried a placeholder of the game date at 19:00 UTC; that has been removed). Events with a null start time are still served because their prices are real, but they are left out of any window you ask for with `commenceTimeFrom`, `commenceTimeTo`, `date` or `live=true`, since the question cannot be answered for them; call the same endpoint without those parameters to see them. Outrights and futures are the exception: a `markets=outrights` event is a market rather than a fixture and never has a kickoff, so it is returned whether or not you narrow the board. Guard for `null` before parsing, on `/odds`, `/events`, `/props`, `/scores` and the historical endpoints alike. - **Sport keys:** lowercase snake_case strings. Examples: `baseball_mlb`, `basketball_nba`, `soccer_epl`, `table_tennis_czech_liga_pro`. Full list at `/v1/sports?all=true`. - **Bookmaker keys:** lowercase, underscores. Example: `pinnacle`, `draftkings`, `fanduel`, `bovada`, `unibet`. Full registry at `/v1/bookmakers?all=true`. - **Region codes:** `us`, `us2`, `uk`, `eu`, `au`, `fr`, `ca`, `br`, `mx`, `latam`, `asia`. Comma-separated when multiple. Per-region book lists are NOT reproduced here: `GET /v1/meta/regions` publishes them with a per-book status (`active` / `paused` / `retired` / `not_yet_integrated`) and a last-write age, computed from the last 24h of writes. Read `active_books` for coverage; `books` is the wider set the `regions=` filter lets through and includes books that currently return nothing. - **Odds format:** default American (e.g. `-115`, `+250`). Pass `oddsFormat=decimal` query param for decimal (e.g. `1.87`, `3.50`). - **Market keys:** `h2h` (moneyline), `spreads`, `totals`, plus `player_*` for player props. Full list in section 8. Standard event-level response shape (`/v1/sports/{sport_key}/odds`): ```json [ { "id": "abc123def456", "sport_key": "baseball_mlb", "sport_title": "MLB", "commence_time": "2026-05-04T19:00:00Z", "home_team": "Boston Red Sox", "away_team": "Houston Astros", "bookmakers": [ { "key": "pinnacle", "title": "Pinnacle", "last_update": "2026-05-04T18:55:14Z", "markets": [ { "key": "h2h", "last_update": "2026-05-04T18:55:14Z", "outcomes": [ {"name": "Boston Red Sox", "price": -135}, {"name": "Houston Astros", "price": +120} ] }, { "key": "spreads", "last_update": "2026-05-04T18:55:14Z", "outcomes": [ {"name": "Boston Red Sox", "price": -105, "point": -1.5}, {"name": "Houston Astros", "price": -115, "point": +1.5} ] }, { "key": "totals", "last_update": "2026-05-04T18:55:14Z", "outcomes": [ {"name": "Over", "price": -110, "point": 8.5}, {"name": "Under", "price": -110, "point": 8.5} ] } ] } ] } ] ``` Player-prop response (`/v1/sports/{sport_key}/props`): ```json [ { "event_id": "abc123def456", "sport_key": "baseball_mlb", "home_team": "Boston Red Sox", "away_team": "Houston Astros", "commence_time": "2026-05-04T19:00:00Z", "player_name": "Tarik Skubal", "market_key": "player_strikeouts", "market_label": "Strikeouts", "line": 7.5, "over_price": -118, "under_price": -102, "bookmaker": "pinnacle", "last_update": "2026-05-04T18:55:14Z", "injury": { "status": "Out", "description": "Skubal (forearm) will not throw this week, per the manager.", "date": "2026-05-01T23:18Z", "team": "Detroit Tigers", "team_abbr": "DET", "il_category": "O", "body_part": "Forearm", "side": "Left", "position": "SP", "expected_return": "2026-05-20", "updated_at": "2026-05-04T18:50:00Z" } } ] ``` The `injury` object is present only for a player who has a current ESPN injury record; no key means no record, which normally means healthy. It is rebuilt every 10 minutes and covers MLB, NBA, WNBA, NHL, NFL and NCAAF. `description` is ESPN's short comment with a fallback to the injury detail string, and a detail that is only ESPN's "Not Specified" placeholder counts as absent. Coverage is a proportion, not a fixed count, because that rebuild tracks the injury report: about 97% of records carry a description (830 of 858 on the 2026-09-05 prod cache); the rest are null rather than filled in, and the raw `detail` is still served verbatim by the `/injuries` endpoints. `team` and `team_abbr` are resolved from ESPN's own team id and are null for an id outside those leagues, never borrowed from another league. The same record is served in full by `/v1/sports/{sport_key}/injuries`. Historical closing-odds response (`/v1/historical/sports/{sport_key}/closing-odds`): ```json [ { "game_date": "2026-05-02", "sport_key": "baseball_mlb", "home_team": "Detroit Tigers", "away_team": "Texas Rangers", "commence_time": "2026-05-02T23:15:00Z", "bookmaker": "pinnacle", "bookmaker_title": "Pinnacle", "player": "Keider Montero", "market_key": "player_strikeouts", "market_label": "Player Props", "line": 4.5, "over_odds": +126, "under_odds": -169 } ] ``` ## 5. Endpoint reference ### `GET /v1/sports` List every supported sport_key. Public, no auth, free. Query params: - `all` (bool, default false): include inactive seasonal sports. Response: array of sport descriptors. ```json [ {"key": "baseball_mlb", "group": "Baseball", "title": "MLB", "description": "US Major League Baseball", "active": true, "has_outrights": false}, {"key": "soccer_epl", "group": "Soccer", "title": "Premier League", "description": "English Premier League", "active": true, "has_outrights": true} ] ``` ### `GET /v1/sports/{sport_key}/events` Upcoming and live games for a sport. Query params: - `commenceTimeFrom` (ISO 8601, optional): only events at or after this time. - `commenceTimeTo` (ISO 8601, optional): only events at or before this time. - `dateFormat` (`iso` or `unix`, default `iso`). - `eventIds` (comma-separated, optional): filter to specific events. Response: array of `{id, sport_key, sport_title, commence_time, home_team, away_team}`. ### `GET /v1/sports/{sport_key}/participants` Teams (or players for individual sports) that have ever appeared in events for this sport. Useful for autocomplete. Response: array of `{full_name, id}`. ### `GET /v1/sports/{sport_key}/odds` Current moneyline / spread / total odds across all bookmakers for upcoming and live events. Query params: Repeating a list parameter is the same as the comma form. `?markets=h2h&markets=spreads` and `?markets=h2h,spreads` are one request and are billed identically: you get the union, not the last occurrence. This holds for `markets`, `bookmakers` and `regions` on every endpoint that takes them, REST, SSE and WebSocket alike. A value repeated across occurrences is counted once, so `?regions=us®ions=us` costs one region. - `regions` (comma-separated, default `us`): which regional book sets to include. Combine `us,eu,uk,au` for global coverage. - `markets` (comma-separated, default `h2h`). This endpoint serves exactly: `h2h`, `spreads`, `totals`, `alternate_spreads`, `alternate_totals`, `outrights`, and any `player_*` / `batter_*` / `pitcher_*` / `anytime_*` / `futures_*` prop key. Any other catalogued key is still accepted and the request is still answered (no 400: a valid derived market never hard-fails here), but it returns nothing on this endpoint and costs nothing. It comes back in the `x-markets-unservable` response header, with the endpoint that owns it in `x-markets-served-elsewhere`. - Period keys (`h2h_1st_half`, `spreads_1st_half`, `totals_1st_half`, `h2h_1st_quarter`, `h2h_1st_period`, `h2h_1st_5_innings`, `spreads_1st_5_innings`, `totals_1st_5_innings`) are served by `GET /v1/sports/{sport_key}/live/period_markets?period=1H&market=h2h` and `GET /v1/historical/sports/{sport_key}/period_markets`. Until 2026-09-05 /odds charged markets x regions for them and dropped them from the response. - `team_totals`, `btts`, `correct_score`, `double_chance`, `draw_no_bet`, the MMA specials and the `horse_*` racing keys are served by `GET /v1/sports/{sport_key}/props?markets=`. - `GET /v1/markets` carries a `served_by` field on every catalogued key. - `bookmakers` (comma-separated, optional): filter to specific books like `pinnacle,draftkings,fanduel`. - `oddsFormat` (`american` or `decimal`, default `american`). - `eventIds` (comma-separated, optional): only these events. - `live` (bool, default false): when true, returns only events whose `commence_time` is at or before now (in-play). No extra cost. Equivalent to passing `commenceTimeTo=`. For a dedicated in-play endpoint with live-tagged player props, use `/v1/sports/{sport_key}/live` instead. Both sides of a two-way price always come from the same fixture, and from the same phase of it. When the same two teams or players meet twice in a day, each meeting is priced only from what a book posted for that meeting. A side that book has not posted for this fixture comes back with a null price rather than being filled from another match, so a null price is an absent quote and never a value we worked out for you. Charges [markets specified] x [regions specified] credits per call, minimum 1 (regardless of `live`). You are only ever charged for markets this endpoint can serve: an unservable key is dropped from the markets x regions multiplier, not billed and then dropped from the response. The request itself is never refused for it. Every charged response carries `x-markets-served` (the keys the charge covered), plus `x-markets-unservable` and `x-markets-served-elsewhere` when some key could not be served here. A servable key that no book is pricing right now still costs a credit and still appears in `x-markets-served`; that is coverage, not a gap. Freshness: every bookmaker block carries `stale_seconds` and `last_update_ms`, and both describe the OLDEST price in that block, so a fresh price on one side of a market never dates a stale one on the other. A book whose last price for a fixture is older than our 10 minute window is re-served for up to one hour, past which the book is omitted from that market rather than served as current; a block that came from that re-serve carries `"topped_up": true`, on the block, covering every market listed under that bookmaker. ### `GET /v1/sports/{sport_key}/events/{event_id}/odds` Full odds for one specific event including all available markets (game lines plus player props if any). Query params: same as `/odds`. Same billing (markets x regions on the servable keys only), same servable market list and the same `x-markets-*` headers: it is the same query scoped to one event. ### `GET /v1/sports/{sport_key}/scores` Live and final scores for in-progress and recently completed games. Query params: - `daysFrom` (int, 1-14, omitted by default): how many days back to include completed games. Costs a second credit (2 instead of 1), and only on sports we hold score history for; on any other sport it is ignored and you are charged the base 1 credit. Response: array of `{id, sport_key, commence_time, home_team, away_team, completed, scores: [{name, score}], last_update}`. ### `GET /v1/sports/{sport_key}/props` Player props for upcoming and live games. Query params: - `markets` (comma-separated): filter to specific prop market keys like `player_points,player_rebounds`. See section 8 for full list. - `bookmakers` (comma-separated): filter to specific books. - `oddsFormat` (`american` or `decimal`). - `player` (substring): filter to a specific player. - `include_event_markets` (bool, default false): include futures and prediction-market rows that lack a single home/away team. Auto-enabled when `bookmakers` includes `polymarket` or `kalshi`. For a dedicated prediction-market endpoint with question text + event_url, use `/v1/prediction-markets/{sport_key}` instead. ### `GET /v1/sports/{sport_key}/props/coverage` Reports which bookmakers cover which prop market types for the sport. No credit cost. Response: `{markets: [{market_key, bookmakers: [{key, title, sample_count}]}]}`. ### `GET /v1/sports/{sport_key}/props/markets` List of available prop market keys for the sport. No credit cost. ### `GET /v1/sports/{sport_key}/line-movement` Time-series price history for one event, grouped into a series per `(source, player, market_key, line)`. 2 credits per call. Query params: - `eventId` (required; `event_id` is an alias). Accepts the `canonical_event_id` or the `event_id` from a `/props`, `/odds` or `/events` row. - `market` (optional; `market_key` is an alias), expanded to its synonym group. - `player` (optional): partial-match player name. Recommended, it is what keeps a busy event under the row cap. - `bookmaker` (optional; `source` is an alias): single book. - `hours` (default 24, max 168) or `window_minutes` (max 10080). Response: an array of `{event_id, home_team, away_team, matched_by, source, player, market_key, line, snapshots: [{timestamp_ms, time, over_price, under_price, line}], count, opening_over, current_over, over_movement, opening_under, current_under, hours_tracked}`. An EMPTY result is an object, not an array: `{movements: [], count: 0, event_id, sport_key, row_cap, min_snapshots_per_series, filters, note}`. That is the shape on EVERY empty path, including an `eventId` that resolves to no event, and it is identical on a cache hit and a cache miss. The two `X-Line-Movement-*` headers are present on empty responses too. Player-keyed books. PrizePicks props carry no team at all (34,911 of 34,911 rows in a one-hour prod sample on 2026-09-05); sleeper, underdog, betr, pinnacle, draftkings and caesars each write a smaller teamless tail. Those series are resolved by `player_name` + `market_key` + `sport_key` + `game_date`, the identity `/props` already publishes them under, so the `canonical_event_id` on a PrizePicks `/props` row works here directly. `matched_by` is `"team"` when the book stated the fixture (and `home_team`/`away_team` are that fixture) or `"player"` when it stated only the player (and the team fields are empty strings, as `/props` serves them). A team is never inferred onto a player-keyed row. Two limits of that matching: the only identity a teamless row carries is `(sport_key, game_date, player_name)`, so two athletes sharing a name on one slate arrive as ONE series (still `matched_by: "player"` with empty teams - a grouping, not a stated fixture); and a team-keyed `eventId` looks up at most the first 300 player names (alphabetically) from that event's team-keyed rows. Passing `player` sidesteps both. Grouping: a series is one `(source, player, market_key, line)`, so a book that MOVES its line produces one series per line rather than one series showing the move; read the moves off the series' time ranges. `over_movement` is the price change at a fixed line, not a line change. Books that quote no price: PrizePicks and Betr carry no price at all (0 of 34,982 prizepicks rows and 0 of 8,657 betr rows had an over price in a one-hour prod sample on 2026-09-05), so their series return `over_price`, `under_price`, `opening_over`, `current_over` and `over_movement` as null and all of their movement is in `line`. Underdog and Sleeper do carry prices. `/props` normalizes DFS flat payouts to +100/-100; this endpoint serves the raw row, so the two differ by design. Limits: - Live table only, for every book. This reads `prop_snapshots`, which holds roughly the last 6.5 hours, so `hours=168` is accepted and clamped by the data rather than by an error. Resolving a player-keyed `eventId` searches that same window, so a book that pulled its slate hours ago still resolves. Older prices are served by `/v1/historical/sports/{sport_key}/closing-odds`, which is a CLOSING line per market, not a movement series. For PrizePicks and Betr not even that exists: they have 0 rows in the closing archive (of 40,594,128), so a PrizePicks series older than the live table is not available from any endpoint. Underdog (1,336,439 rows) and Sleeper (46,231) are archived. Measured on prod 2026-09-05. - 5,000-row cap per request, most recent first. `X-Line-Movement-Row-Cap` is on every response and `X-Line-Movement-Truncated: 1` says the cap bound; when it does, `opening_over` is the oldest price in the returned slice, not the true open. It bound on 275 of 7,072 team-keyed events over a 24-hour lookback in a prod sample. A `player` or `market` filter avoids it. - A series needs at least 2 snapshots, so a price quoted once and never moved does not appear. ### `GET /v1/sports/{sport_key}/futures` Season-long futures markets like championship winner, MVP, division winner, total wins. ### `GET /v1/sports/{sport_key}/live` In-play events only. Pulls from odds_snapshots and filters to events whose commence_time has passed. Query params: same as `/odds`. 3 credits. ### `GET /v1/sports/{sport_key}/compare` Side-by-side line comparison across all bookmakers for each event, with best-line highlight per outcome. Query params: - `markets` (default `h2h`). - `oddsFormat`. 5 credits per call. Response: array of `{event_id, home_team, away_team, commence_time, market_breakdown: [{market_key, outcomes: [{name, prices: [{book, price, point}], best: {book, price}}]}]}`. ### `GET /v1/sports/{sport_key}/arbitrage` Pre-computed cross-book arbitrage opportunities, refreshed every 30 seconds. Query params: - `min_profit` (decimal, default 0.005, i.e. 0.5%): minimum guaranteed-profit threshold. Response: array of `{event_id, market, legs: [{book, side, price, recommended_stake}], profit_pct, time_to_close_minutes}`. Soccer and other 3-way (home/draw/away) markets are fully supported, including arbs anchored on the draw. ### `GET /v1/sports/{sport_key}/ev` Pre-computed +EV opportunities vs the no-vig consensus. Each row includes the consensus fair price for verification. Three-way soccer markets use a dedicated no-vig pass that normalizes home/draw/away to fair probabilities, so +EV on the draw surfaces too. Query params: - `min_edge` (decimal, default 0.02, i.e. 2%). Response: array of `{event_id, market, side, book, price, ev_percent, fair_price, sample_books_n, time_to_close_minutes}`. ### `GET /v1/sports/{sport_key}/consensus` No-vig consensus fair odds across all bookmakers, used as a sharp baseline. Soccer and other 3-way markets return separate home, draw, and away consensus rows (the draw is priced across every book that offers it). ### `GET /v1/verdict` The one-call "should I bet this?" answer for a single specific bet. 5 credits. Instead of stitching `/ev`, `/consensus` and best-line yourself, pass a bet and get back the no-vig fair price, the best available price and which book has it, how your price grades as EV, and a plain-English call. Built for AI assistants: one request, one decision. Query params: - `sport` (required): sport_key, e.g. `baseball_mlb`. - `market` (default `h2h`): `h2h` / `spreads` / `totals`, or a player-prop key (`player_hits`, `player_points`, ...). - `side` (required): the team for h2h/spreads (or `home`/`away`), or `over`/`under` for totals and props. - `home` + `away`, or `team` (one name): identify the game. `event` ("Away @ Home") also works. - `player`: required for player-prop markets. - `line`: the number for spreads, totals, props. - `book`: the book you would bet at (grades that book's current price). - `price`: the price you are offered (American like `-110` or decimal like `1.91`). Overrides `book`, use it to grade a number you already have. - `region`: where you can bet, `us` (default) / `eu` / `uk` / `au` / `ca`. Scopes the best-price and shop recommendation to books available there, so a US bettor is never told to use a euro book. The Pinnacle fair line is still shown as a reference. - `books`: exact CSV of the books you can bet at (e.g. `draftkings,fanduel,novig`). Overrides `region`; use it for state-level geo-blocks. - `bankroll` + `kelly`: when the bet is +EV, returns a suggested `stake` sized by fractional Kelly (default 0.5 = half-Kelly, hard-capped at 25% of bankroll). The response also carries an `edge_alert` when a book shows a price far better than the market (either a rare soft mispricing worth grabbing or a stale line to verify) that the normal best-price guard would otherwise hide. To avoid passing region/books every call, `POST /v1/verdict/prefs` with `region=` or `books=` remembers them per API key; `/v1/verdict` then scopes to them automatically. `GET /v1/verdict/prefs` reads the saved value. Both are free. Response: `{bet, verdict, worth_betting, summary, region, note, fair:{price,implied_prob,source}, best_available:{price,book,implied_prob,edge_pct}, your_bet:{price,book,implied_prob,edge_pct}, shop_to, movement_pp_since_open, books_compared, confidence}`. `note` is set when a bet is only priced by books outside your region (fair value still shown from the sharp reference). `verdict` is `BET` / `LEAN` / `FAIR` / `PASS` / `NO_DATA`. `summary` is a ready-to-speak sentence. The fair line uses the same sharp no-vig math as `/ev` and `/consensus`, so verdicts never contradict those endpoints; the best price is consensus-outlier-guarded (a stale line is never crowned "best"); exchange best-prices carry a liquidity caveat. Fails to `NO_DATA` rather than guessing when too few books price the bet. ### `POST /v1/parlay/verdict` Grade a multi-leg parlay in one call. 10 credits. For a product called ParlayAPI this is the flagship: it reuses the /v1/verdict engine per leg so single-bet and parlay verdicts agree. Body: `{"legs": [ {sport, market, side, home, away | team, player, line}, ... ], "region"?, "books"?, "stake"?, "book"?}`. Provide 2 to 12 legs; each leg is shaped exactly like a /v1/verdict bet. Returns: `{verdict, summary, region, legs:[{leg,bet,fair_price,best_price,best_book,edge_pct}], fair:{price,implied_prob}, best_book_parlay:{book,price,decimal,ev_pct,payout_on_stake}, line_shopping_ceiling, books_that_offer_all_legs, same_game_correlation, weakest_leg}`. What makes it correct where naive parlay math is not: - **Per-book construction.** A real parlay is one slip at one book, so we compute the parlay odds at each book that prices EVERY leg and return the best SINGLE book, not an unplaceable best-of-each. `line_shopping_ceiling` reports the best-of-each price so you can see what the one-book constraint costs. - **Correlation.** Legs from the same game are correlated, so the independent product is not the true price. We detect same-game legs (game lines and props) and set `same_game_correlation` with a note that a book would price them as a same-game parlay. - **Honest EV.** Parlays carry compounded vig, so most grade FAIR or PASS; the summary says so and names the weakest leg. Best-price is scoped to the books you can bet at (region/books/prefs, same as /v1/verdict). ### `GET /v1/sports/{sport_key}/best-bets` What should I bet right now? 10 credits. The discovery counterpart to /v1/verdict: instead of grading a bet you name, it scans the sport's board, grades every candidate with the same no-vig engine, keeps only the plays that are +EV at a book YOU can bet at, and ranks them by edge. Params: `region` (us default / eu / uk / au / ca), `books` (exact CSV, overrides region), `limit` (default 20), `min_edge` (default 2.0), `min_books` (default 4, higher = more reliable), `markets` (optional CSV of market_keys). Returns `{sport, region, count, summary, best_bets:[{bet, market_key, fair_price, best_price, best_book, edge_pct, verdict, books_compared}], edge_alerts:[{bet, book, price, apparent_edge_pct, caveat}], note}`, sorted by edge. Player props priced by at least `min_books` books; prediction markets (Kalshi/Polymarket) and game moneylines are excluded from the ranking (they price differently or belong on /v1/verdict via get_odds), so the list stays trustworthy. `edge_alerts` collects books showing a price far off the market (a rare soft error to grab, or a stale line to verify). Scoped to the books you can bet at (region/books/prefs). Cached ~45s. ### `GET /v1/sports/{sport_key}/middles` Cross-book middle opportunities. A middle takes the Over at a low line on one book and the Under at a higher line on another, so a window of whole numbers cashes BOTH bets (e.g. Over 7.5 at one book, Under 9.5 at another means 8 or 9 wins both). Scans game totals, spreads, AND player-total props (points, rebounds, strikeouts, ...), so it surfaces prop middles most feeds never compute. 3 credits. Query params: - `min_gap` (decimal, default 1.0): minimum window width in points/runs/goals. - `markets` (CSV, optional): limit the scan, e.g. `totals` or `player_points`. - `include_props` (bool, default true): include player-total props alongside game lines. Response: array of `{event_id, home_team, away_team, market, player, middle_window, width, middle_numbers, over_leg, under_leg, profit_if_hit, net_if_above_window, net_if_below_window, breakeven_hit_pct, same_book}`. `profit_if_hit` and `net_if_*` are per $100 staked on each leg. `breakeven_hit_pct` is how often the result must land in the window for the play to be +EV given the vig paid on a miss (lower is better, 0 = free-roll that profits even on a miss). Results are sorted by `breakeven_hit_pct` ascending, so the highest-value plays lead and expensive main-line-vs-deep-alt pairings sink to the bottom; width breaks ties. ### `GET /v1/sports/{sport_key}/closing-lines` Closing-line value (CLV) tracking. Returns the most recent closing prices for completed events. "Closing" is enforced, not assumed: a price is returned only when we can show it was quoted strictly BEFORE the listed start time. A price quoted at or after the start is an in play price, not a closing line, and is excluded, and so is a row whose start time we cannot read, because we cannot attest which side of the start it falls on. A fixture with no such price is therefore ABSENT from the response rather than represented by an in play price. On books that reprice during a match this trims coverage sharply: measured 2026-09-04 over 30 days of table tennis, 54,120 of the 55,353 Bovada side rows this endpoint used to return were quoted after the start time. Treat an absent fixture as "no closing line held", not as "no such fixture". ### `GET /v1/sports/{sport_key}/player-ratings` Market implied player strength ratings for 1v1 sports. Supported today for `table_tennis` and its sub leagues, where we hold paired moneylines from Bovada and Tenbet. 2 credits. The rating is an iterative Elo fit to the de vigged implied win probability of the last price each book posted BEFORE the listed start time. It is not an official ITTF or WTT ranking, it is not a results rating, and it is not a prediction. Any price quoted at or after the start time is an in play price and is excluded, because an in play price mostly encodes who is currently ahead rather than who is stronger. `rating` and `implied_win_rate` are derived numbers, computed by ParlayAPI from book prices. Selection rules, all reported back in the response: a fixture is keyed by (home player, away player, start time), so the same two players meeting twice in one day counts as two fixtures and neither borrows the other's price; both sides must have a pregame price or the fixture is dropped; the two implied probabilities must sum to a plausible book total (0.98 to 1.30) or the fixture is dropped; one fixture counts once no matter how many books priced it; a book names the side either on its own ("Adam Svoboda") or inside a compound market label ("Adam Svoboda v Vaclav Dolezal · Match Winner · Adam Svoboda"), both are read, and the trailing name must match a side exactly. Query params: - `limit` (int 1 to 500, default 100): how many players to return, highest rating first. - `min_matches` (int 1 to 50, default 3): drop players with fewer used fixtures than this. - `window_days` (int 1 to 180, default 30): how far back to look for pregame closing prices. Response: `{sport_key, rating_kind, rating_basis, rating_method, window_days, data_window_start, data_window_end, min_matches, total_rated_players, matches_used, matches_dropped_inplay_only, matches_dropped_one_sided, matches_dropped_implied_total_out_of_range, matches_priced_by_multiple_books, implied_total_bounds, source_matches, ratings[], _note}`. Each entry of `ratings` is `{player, rating, matches, implied_win_rate, last_match_at, last_seen}`. `matches_used` is the number of fixtures behind the ratings; `matches_dropped_inplay_only` counts fixtures for which we hold a match winner price named to a side but every such price was quoted at or after the start; fixtures we hold no named match winner price for are not in that count at all; `data_window_start` and `data_window_end` are the first and last fixture actually used, which can be narrower than `window_days`. `source_matches` is retained as an alias of `matches_used`. Coverage is limited by how many pregame prices we hold, so expect `matches_used` to be far smaller than the fixture count in the window. ### `GET /v1/historical/sports/{sport_key}/odds` Historical odds snapshots. 10 credits per market per region requested (minimum 10). Query params: - `date` (ISO 8601, required): timestamp of the snapshot you want. We round to the nearest snapshot we have. - `regions` (default `us`). - `markets` (default `h2h`): `h2h`, `spreads`, `totals` and nothing else. The archive this reads has moneyline, spread and total columns only, so no alt ladder, no outrights and no props. Any other key is answered but excluded from the 10-credits-per-market charge and named in `x-markets-unservable`. Prop history is `GET /v1/historical/sports/{sport_key}/closing-odds?markets= `, period history is `GET /v1/historical/sports/{sport_key}/period_markets`, and `outrights` plus the alt ladder are live-only on `GET /v1/sports/{sport_key}/odds`. - `bookmakers` (optional). - `oddsFormat`. Response: same shape as `/v1/sports/{sport_key}/odds` but reflecting the state at the historical timestamp, with one difference you MUST handle: on this endpoint `last_update` and `commence_time` are nullable, and are null on most rows today. Each bookmaker block carries `last_update` (the real capture time of that archive row, from `raw_json.snapshot_ts_ms`) plus `last_update_source`, which is `archive_snapshot` when the stamp is real, `unavailable` when the archive holds no capture time for that row, and `error_no_capture_column` if our read path could not see the column at all. A null `last_update` means "we do not know when this price was captured", never "the price is bad" and never a parse failure. `commence_time` is null on events whose start time was never recorded. Guard both before parsing; do not substitute a value of your own. Coverage, measured 2026-08-14, because you should size this before building on it: only rows written by the totals and spreads promotion paths carry a capture time. On baseball_mlb game_date 2026-08-10, 68 of 397 bookmaker blocks were stamped, and none of the 329 blocks carrying an h2h market were, nor any of the 177 `_open` blocks. Archive-wide 62,301 of 1,848,882 rows carry a stamp; for `_open` rows it is 0.2 percent. Moneyline and opening rows only start carrying real stamps for dates promoted after 2026-08, so closing-line-value analysis cannot yet sort on `last_update` for older dates, and the rows already in the archive cannot be backfilled because the source snapshots for those dates are past retention. Before 2026-08 this endpoint emitted a hardcoded `T19:00:00Z` for every bookmaker block and for every missing `commence_time`. That constant was not a measurement. It has been removed rather than replaced, per the data-integrity policy in section 14: if we do not have it, the field is null. ### `GET /v1/historical/sports/{sport_key}/closing-odds` Historical closing lines. 10 credits per call. Query params: - `markets`: comma-separated. Mix game-line markets (`h2h`, `spreads`, `totals`) with player prop markets (`player_strikeouts`, `player_points`, etc.) freely. - `bookmakers` (default `pinnacle`). - `season` (e.g. `2023-24`). - `date` (YYYY-MM-DD): shortcut for dateFrom=dateTo=date. - `dateFrom`, `dateTo` (YYYY-MM-DD). - `player` (substring): filter props to a specific player. - `oddsFormat`. Player-prop closing lines route to `prop_closing_lines` (30M+ rows back to June 2022, dense from 2026-04-07 forward). Game-line closing rows route to `historical_odds` (1.7M+ rows, continuous from 2005 for NFL and soccer). `GET /v1/historical/stats` serves the live game-line row count and the per-sport date ranges; the figures here are floors. ### `GET /v1/historical/sports/{sport_key}/period_markets` Durable archive of period-market line movement (1H, Q1-Q4, halves, P1-P3, F5/F7) across every distinct (line, price) state per match. 5 credits per call. Use case: replay how a Q3 NBA total moved during the game. Each row carries `first_seen_ms` (when the book first wrote that exact state) and `last_seen_ms` (the latest poll that re-confirmed it). To reconstruct movement, order by `first_seen_ms` within a `(match_id, period_key, market, side)` group. Query params: - `period`: FT / 1H / 2H / Q1 / Q2 / Q3 / Q4 / OT / P1 / P2 / P3 / F5 / F7 or `all`. - `match_id`: source-native event id, optional. - `source`: pinnacle / draftkings / fanduel / betmgm / caesars / betrivers / fanatics / unibet / bet365. - `market`: spread / total / h2h. - `home_team`, `away_team`: substring filters. - `dateFrom`, `dateTo` (YYYY-MM-DD). - `limit` (default 5000, max 20000). Backed by `period_odds_archive`, which compresses the high-volume `period_odds_snapshots` rolling tick stream into one row per distinct state. Backfilled at table-create time; live writes are appended as the collector polls Pinnacle. ### `GET /v1/bookmakers` List of supported bookmakers with their integration status. Query params: - `all` (bool, default false): include merged / decommissioned / not_yet_integrated entries. - `include_endpoints` (bool, default true): attach `endpoints` array (categories like `game_lines`, `live`, `props`, `prediction`, `event_markets`, `historical`) and `example_paths` (one curl-ready URL per category) to each entry. Pass `false` for the lean catalog. Response: array of `{key, title, region, status, [endpoints], [example_paths], [merged_into], [note]}`. Status values: `active`, `merged`, `decommissioned`, `not_yet_integrated`. ### `GET /v1/bookmakers/{key}` Detail view for one bookmaker: same shape as one element of `/v1/bookmakers` but always includes `endpoints` + `example_paths`. Accepts a few common aliases (`dk` -> `draftkings`, `draftkings_an` -> `draftkings`, `sbr_close` -> `pinnacle`, etc.) and returns `alias_resolved_from` when one is used. 404 returns `{detail: {error, key_requested, available_keys: [...]}}` so callers can recover. ### `GET /v1/prediction-markets/{sport_key}` Real-time Kalshi + Polymarket prices for the sport. 1 credit. Query params: - `sources` (comma-separated, default `kalshi,polymarket`): which prediction-market venue(s) to include. Polymarket rows include the source-native question, outcome label, slug-derived `event_url`, and reported `volume`/`liquidity`. Kalshi rows include the ticker. Responses are cached server-side for 30 seconds; `X-Cache: HIT` (with `X-Cache-Age-Seconds`) or `X-Cache: MISS` on the response tells you whether the request hit Postgres or the cache. For free-text discovery across Kalshi, Polymarket, and Novig (no credit charge), use `/v1/event-markets/search` instead. ### `GET /v1/usage` Your account usage for the current billing period. Authenticated. Response: `{period, requests_used, requests_remaining, tier, by_endpoint: {...}}`. ### `GET /v1/stats` Live API throughput stats. Public, no auth. ### `GET /v1/historical/coverage` Live coverage map of the historical archive. Public. Response: total rows, sources count, sports count, per-sport breakdown. ### `GET /v1/pinnacle-coverage` Pinnacle's specific coverage matrix per sport. Public. ### `GET /health` Liveness probe. Returns `{ok: true, version, timestamp}`. Public. ## 6. Sport keys 90+ active sport keys. `GET /v1/sports?all=true` is the authoritative list and the authoritative count; the categories below are a reading aid, not an enumeration. Major categories: **Baseball**: `baseball_mlb`, `baseball_kbo`, `baseball_npb`, `baseball_mexican_league`. **American Football**: `americanfootball_nfl`, `americanfootball_ncaaf`. **Basketball**: `basketball_nba`, `basketball_ncaab`, `basketball_wnba`, `basketball_euroleague`. **Ice Hockey**: `icehockey_nhl`, plus various international leagues. **Soccer**: 50+ leagues including `soccer_epl`, `soccer_france_ligue_one`, `soccer_germany_bundesliga`, `soccer_spain_la_liga`, `soccer_italy_serie_a`, `soccer_uefa_champs_league`, `soccer_uefa_europa_league`, `soccer_uefa_europa_conference_league`, `soccer_usa_mls`, `soccer_mexico_ligamx`, `soccer_brazil_campeonato`, etc. **Tennis**: `tennis_atp_french_open`, `tennis_wta_french_open`, plus tournament-specific keys. **Table Tennis**: use the umbrella key `table_tennis`, which is live (35 events on the board when last measured, 2026-08-26, sourced from Bovada). The per-league keys `table_tennis_czech_liga_pro`, `table_tennis_tt_elite_series`, `table_tennis_tt_cup`, `table_tennis_tt_cup_women` and `table_tennis_setka_cup` resolve but currently returns nothing: measured 0 live events on each, and 0 historical matches on sampled dates back to 2026-05-01. Query the umbrella instead of the league keys. **MMA**: `mma_mixed_martial_arts`, `mma_ufc`, `mma_mvp`. **Boxing**: `boxing_boxing`. **Golf**: `golf_pga_championship`, `golf_pga_us_open`, `golf_masters`, `golf_open_championship`, plus tournament keys. **Cricket**: IPL, T20I, etc. **Esports**: `esports_dota_2`, `esports_csgo`, `esports_lol`, `esports_valorant`, plus tournament-specific. **Rugby League / Aussie Rules / Volleyball**: niche, intermittent coverage. ## 7. Bookmaker registry 30+ active bookmakers. `GET /v1/bookmakers` is the authoritative list and the authoritative count; `?all=true` adds the merged and decommissioned keys with their status. ### Active US-licensed sportsbooks `draftkings`, `fanduel`, `betmgm`, `caesars`, `betrivers`, `fanatics`, `hardrock`, `parx`, `bet365` (UK-listed but licensed in NJ/PA/etc.), `bovada` (offshore), `pinnacle` (offshore). ### Active French-licensed sportsbooks `pmu`, `unibet`. Both are ARJEL-licensed and meaningful to French market customers. ### Active EU sportsbooks The country-licensed Unibet feeds `unibet_be` (Belgium) and `unibet_nl` (Netherlands). Kindred runs these as separate licences with separate prices, so they are separate keys here; `/v1/meta/parser-coverage` rolls them back up under the operator when you want one Unibet. ### Active Canadian sportsbooks `betrivers_ca`. (`maverick_games` is retired: the operator closed its sportsbook on 2026-09-01, so live endpoints refuse the key, while its closing lines captured through 2026-09-01 stay queryable on the historical, closing-line and bulk export endpoints with a `retired: true` marker on each row; games dated after the closure are not served for it.) ### Active Australian sportsbook `sportsbet_au`. ### Active LATAM sportsbook `rushbet`. ### Active DFS apps `prizepicks`, `underdog`, `sleeper`, `pick6` (DraftKings), `betr`. ### Active US sweepstakes sportsbooks `fliff`. Not a DFS pick-em app: it posts real two-sided American prices with juice on both sides, plus a full player-prop book. Measured 2026-07-31 over six hours: 24,394 of 24,396 `baseball_mlb` prop rows two-sided across 24 market keys, 1,572 of 1,572 `basketball_wnba` rows across 13 keys. Hold runs well above the US retail band, so treat it as a soft book rather than a price anchor. Served on `/v1/sports/{sport_key}/props`. ### Active exchanges `novig`. ### Active prediction markets `kalshi`, `polymarket`, `robinhood` (Robinhood Event Contracts). ### Special-status entries - `zebet` (status=`merged`, merged_into=`unibet`): redirects to Unibet since 2026. - `fdj_parionssport` (status=`decommissioned`): online sportsbook wound down in 2026, brand survives at retail only. - `pointsbet` (status=`decommissioned`): the US book was absorbed into Fanatics. It is not served on any live endpoint. Its archived rows survive under `pointsbet_an` in `historical_odds` and are still queryable via `/historical`. - `prophetx` (status=`suppressed`): only sandbox credentials exist, so the serving layer drops the source before a response is assembled. Novig is the live exchange. - `netbet` (status=`not_yet_integrated`): on roadmap. When a customer requests one of these specifically, return the merged_into target or explain the status. The /v1/bookmakers endpoint exposes the full status with note text. ## 8. Market keys ### Game-line markets | Key | Description | |---|---| | `h2h` | Moneyline (head-to-head winner, 2 or 3 outcomes) | | `spreads` | Point spread / handicap | | `totals` | Over/under total points/runs/goals | | `outrights` | Futures: championship winner, division winner, etc. | | `h2h_lay` | Exchange lay side (Novig) | ### Player prop markets: MLB `player_strikeouts`, `player_total_bases`, `player_hits`, `player_home_runs`, `player_runs`, `player_rbis`, `player_walks`, `player_stolen_bases`, `player_singles`, `player_doubles`, `player_triples`, `player_hits_allowed` (pitcher), `player_walks_allowed` (pitcher), `player_outs` (pitcher), `player_earned_runs` (pitcher). ### Player prop markets: NBA `player_points`, `player_rebounds`, `player_assists`, `player_threes`, `player_blocks`, `player_steals`, `player_turnovers`, `player_pts_rebs_asts`, `player_pts_rebs`, `player_pts_asts`, `player_rebs_asts`, `player_double_double`, `player_triple_double`. ### Player prop markets: NFL `player_pass_yds`, `player_pass_tds`, `player_pass_completions`, `player_pass_attempts`, `player_pass_interceptions`, `player_pass_longest`, `player_rush_yds`, `player_rush_attempts`, `player_rush_longest`, `player_receptions`, `player_receiving_yds`, `player_receiving_longest`, `player_anytime_td`, `player_first_td`, `player_kicking_points`. ### Player prop markets: NHL `player_shots_on_goal`, `player_goals`, `player_assists`, `player_points` (G+A), `player_saves`, `player_power_play_points`, `player_blocks`, `player_anytime_goalscorer`. ### Soccer team-derivative markets `btts` (both teams to score), `correct_score`, `double_chance`, `total_goals_odd_even`, `winning_margin`, `exact_total_goals`, `first_team_to_score`, `half_time_full_time`, `draw_no_bet`, `winner_and_total_goals`. Full canonical key list lives in `src/api/sports_config.py` and is enforced server-side. Use `GET /v1/sports/{sport_key}/props/markets` for the runtime list per sport. ## 9. Historical archive depth by sport Total rows: 1.7M+ in `historical_odds` (game lines), 30M+ in `prop_closing_lines` (player props, dense from 2026-04-07 forward). Both are floors and both grow daily. `GET /v1/historical/stats` is the live game-line count. | Sport | Earliest game-line date | Source(s) | |---|---|---| | NFL | 2005 (continuous; earlier seasons are sparse seed rows) | `nflverse_pbp` (MIT), `sbr_close`, `opening_line`, AN | | NBA | 2017-10-17 | `hoopr_nba` (MIT), `sbr_close`, AN | | NCAAF | 2014-08-28 | CFBD (`cfbd_consensus`, `cfbd_teamrankings`, `cfbd_numberfire`, plus per-book `bovada`, `williamhill_us`, `espnbet`, `caesars`, `draftkings`, etc.) | | MLB | 2010-04-04 | `sbr_close`, `*_an` (DK, FD, MGM, Caesars, Fanatics, bet365, BetRivers, PointsBet) | | NHL | 2007-10-03 | `sbr_close`, `*_an` | | Soccer | 2005-08-13 (EPL etc.) | football-data.co.uk per-league CSVs (bet365, pinnacle, betway, williamhill, interwetten, ladbrokes, betvictor, betfair_exchange, plus closing variants) | | Tennis ATP/WTA | early 2010s | `bet365`, `pinnacle` daily snapshot accumulated | Player prop closing lines: the archive becomes dense on 2026-04-07 across all sports (that is the cutover when the daily snapshot collector started persisting closing lines). Exactly one stray row predates it (2024-05-13); ignore it, there is no usable 2024 or 2025 prop history. Growth is measured in the hundreds of thousands of rows per day and scales with the number of leagues in season, so size a backfill from `GET /v1/historical/stats` rather than from a rate quoted here. For pre-2026 player prop history, no public open-data archive exists at scale; the documented escape hatch is the customer BYO-data import endpoint (under construction as of 2026-05-04). ## 10. Update cadence - Game-line odds (h2h/spreads/totals): refreshed every 30-60s per book. - Player props: active books polled every ~30-120s per source. /props serves the latest row per book from the last 60 minutes, so a quiet market can be several minutes old. Every row carries age_seconds (the real write age); pass ?maxAgeSec=N to drop anything older than N seconds. - Live in-play odds: refreshed every 5-15s during games. - Scores: every 30s during games, every 5min when no live games. - Historical archive (soccer): football-data.co.uk pulls run weekly on Tuesdays at 11:00 UTC. - Historical archive (US sports): forward-going daily snapshot from Pinnacle plus per-source backfills (nflverse, hoopR, CFBD) on cadence per release. - Prop closing lines: daily snapshot at game start. - Affiliate payouts: monthly cron on the 1st at 14:00 UTC. ## 11. Error codes | HTTP | Meaning | Action | |---|---|---| | 200 | Success | Use response | | 400 | Bad request (invalid sport_key, malformed params) | Check error.detail field for specifics | | 401 | Missing or invalid API key | Verify `X-API-Key` header is set | | 403 | Credit limit exceeded for the period | Wait for next month's reset, or upgrade tier | | 404 | Sport key not found | Use `/v1/sports?all=true` to discover valid keys | | 429 | Rate limit hit (per-second burst limit) | Back off and retry; default burst is 60 req/sec | | 500 | Server error | Retry once; if persistent, email support@parlay-api.com with the request ID from response headers | | 502 | Upstream bookmaker timeout | Same as 500; usually resolves within seconds | | 503 | Maintenance window | See `/changelog` for scheduled work | Error response body shape: ```json {"detail": {"error": "INVALID_SPORT_KEY", "message": "Unknown sport key 'baseball_xyz'. Use GET /v1/sports to list valid keys."}} ``` ## 12. WebSocket protocol Business+ tier only. Endpoints: - `wss://parlay-api.com/ws/odds/{sport_key}?apiKey=YOUR_KEY` for game-line + prop diffs - `wss://parlay-api.com/ws/live/{sport_key}?apiKey=YOUR_KEY` for the live board's feed: game lines plus the moneylines the board overlays on each card. Narrower than `/ws/odds` rather than a live-only view of it, it sends no `initial_state` frame (a `connected` frame, then diffs) and ignores the `/ws/odds` query filters. Same rows for a Business key as for the dashboard cookie; send `{"type":"subscribe","event_id":"..."}` to get one game in full. Authentication is the same on both sockets, and the key may arrive in any of three forms: - `X-API-Key: YOUR_KEY` header (recommended: keeps the key out of URLs and access logs) - `?apiKey=YOUR_KEY` query param (for browser `WebSocket`, which cannot set headers) - `?api_key=YOUR_KEY` query param (identical to `?apiKey=`; both spellings are accepted) A logged-in dashboard session cookie is a credential on `/ws/live` only, the free board's own feed. `/ws/odds` and `/ws/odds-fast` are metered per API key and refuse a cookie with 4003, from any browser, because a cookie carries no key for the credit allowance to meter. If both a key and a cookie are present, the key wins. Before 2026-09-05 the `/ws/live` routes took the cookie and nothing else and closed every API key with 4001 "Not logged in"; they now share one auth path with `/ws/odds`. Close codes are the same on every WebSocket route: 4003 no key on the request, 1008 key not valid, 4001 tier below Business or an expired session, 4002 concurrent-connection cap, 4004 monthly credits spent. A connect that is refused is not billed. On connect, `/ws/odds` sends `{"type": "initial_state", "data": [...]}` with a snapshot of recent rows (`/ws/live` does not; see above). After that, server pushes incremental diffs as `{"type": "odds_update", "data": [...]}` whenever a price changes upstream. Client can filter to a single event: ```json {"type": "subscribe", "event_id": "abc123def456"} ``` Reconnection: client should reconnect on close with exponential backoff (1s, 2s, 4s, capped at 30s). On reconnect the server replays all rows updated since the last `last_update` timestamp the client received. Each streamed row carries `last_update` (epoch ms of our last write or re-verify for that price), `price_age_s` (server-computed seconds since the price last actually MOVED, so no client clock-skew guesswork), and `line_changed_at_ms` (epoch ms of that last real move). `price_age_s` counts from the real move, not the last write: when a book re-emits an unchanged price as a verification write `last_update` advances but `price_age_s` keeps counting, so a frozen line never reads as fresh. Sharp books like Pinnacle update on a slower cadence, so a larger `price_age_s` there is real, not stale. To keep the live feed honest, a fast book's line that stays frozen beyond about 150s during a commenced game is dropped from the stream rather than sent with a fresh-looking timestamp, matching the `/live` endpoint. Use `price_age_s` to set your own staleness cutoff. Heartbeat: server sends `{"type": "ping"}` every 25s. Client should reply `{"type": "pong"}` within 5s or the connection drops. Full WebSocket reference: https://parlay-api.com/docs/websocket. ### Server-Sent Events (SSE) alternative For clients that can't run a long-lived WebSocket (CORS-restricted browsers, mobile, serverless workers, AI agents), Server-Sent Events stream the same data over plain HTTP with `Content-Type: text/event-stream`: - `https://parlay-api.com/v1/sse/odds/{sport_key}?apiKey=YOUR_KEY`, odds change deltas (game lines + props) - `https://parlay-api.com/v1/sse/hot/{sport_key}?apiKey=YOUR_KEY`, fast-cadence hot books (Pinnacle + FanDuel hot leagues, sub-3s) - `https://parlay-api.com/v1/sports/{sport_key}/live/sse?apiKey=YOUR_KEY`, live play-by-play events with batter/pitcher/scorer metadata On connect, the server sends `data: {"type": "connected", "sport_key": ..., "transport": "sse", "heartbeat_s": 5}\n\n` immediately, then streams diffs as standard SSE `data:` events. Heartbeats fire every 5s so connections survive idle intermediaries. Reconnect on close with exponential backoff just like WebSocket. Python example: ```python import requests KEY = "YOUR_KEY" url = f"https://parlay-api.com/v1/sse/odds/baseball_mlb?apiKey={KEY}" with requests.get(url, stream=True, timeout=None) as resp: for line in resp.iter_lines(): if line.startswith(b"data: "): event = json.loads(line[6:]) print(event) ``` Auth: apiKey must be in the URL query string. SSE clients cannot send custom headers like `X-API-Key` on the initial GET in most environments. Tier: Business+ on `/ws/*`, `/v1/sse/odds/*`, and `/v1/sse/hot/*`. Live play-by-play SSE has separate gating. ## 13. Common AI-agent patterns ### Pattern 1: Live arbitrage bot ```python import time, requests KEY = "YOUR_KEY" while True: arbs = requests.get( "https://parlay-api.com/v1/sports/baseball_mlb/arbitrage", params={"min_profit": 0.005}, headers={"X-API-Key": KEY}, timeout=10, ).json() for arb in arbs: if arb["profit_pct"] > 0.01: alert(arb) time.sleep(30) ``` ### Pattern 2: AI prop-pick model GET `/v1/sports/basketball_nba/props?markets=player_points,player_rebounds,player_assists`, cross-reference with the player's recent stats from your stats source (balldontlie, NBA stats API, etc.), compute edge, rank. Full code skeleton at https://parlay-api.com/cookbook#prop-picks-ai. ### Pattern 3: CLV tracker When a bet is placed (or almost placed): snapshot price via `/v1/sports/{sport_key}/odds`. At game start: query `/v1/historical/sports/{sport_key}/closing-odds`. Compute `CLV = your_price vs closing_price`. Plot cumulatively over 200+ bets. ### Pattern 4: Discord +EV alert bot Combine `/v1/sports/{sport_key}/ev?min_edge=0.04` (every 60s on a cron) with Discord webhook posts. ~50 lines of Python total. Recipe at https://parlay-api.com/cookbook#discord-bot. ### Pattern 5: Tool-using agent (Claude/GPT) Register the OpenAPI spec at https://parlay-api.com/openapi.json as a tool definition. The model calls endpoints directly without you hand-coding wrappers. For MCP servers, auto-convert with `openapi-mcp-generator` or similar. ### Pattern 6: Backtest harness Walk historical-archive snapshots day by day: ```python from datetime import datetime, timedelta def historical_at(sport_key, date_iso): return requests.get( f"https://parlay-api.com/v1/historical/sports/{sport_key}/odds", params={"date": date_iso, "regions": "us", "markets": "h2h"}, headers={"X-API-Key": KEY}, ).json() start = datetime(2024, 1, 1) for d in range(180): day = start + timedelta(days=d) games = historical_at("baseball_mlb", day.strftime("%Y-%m-%dT19:00:00Z")) for g in games: pick = your_strategy(g) if pick: record_pl(pick, settled_result(g)) ``` ## 14. Data integrity policy - Every price is captured from a real bookmaker's real endpoint. We do not interpolate, derive Unders from Overs, estimate from no-vig consensus, or otherwise synthesize. - If an upstream book does not post a price, the field is `null`. We never invent one. - Source attribution is per-row: game-line events carry it as `bookmakers[].key`, prop and futures rows as `bookmaker` (plus `bookmaker_title`), prediction-market rows as `source`, and exchange rows as `exchange`. - Open-source community archives we redistribute (nflverse, hoopR, CFBD, football-data.co.uk) are licensed under MIT or comparable permissive terms and are fully redistributable to our customers. - We do not bulk-import from competitor commercial APIs (OddsJam, The Odds API, OpticOdds) and serve the result through our endpoints. Their TOS prohibits redistribution and that is a corner we do not cut. - Customer-imported historical data (when the BYO-import endpoint ships) lives in a per-API-key namespace, not in the public archive. Customers retain ownership. ## 15. Versioning policy - Current version: 3.2.0. - Stable URL prefix: `/v1/`. - Backward-compatible changes ship continuously without bumping the URL prefix: - Adding new fields to response objects (existing clients ignore new fields) - Adding new endpoints - Adding new query parameters with defaults - Adding new bookmakers, sport keys, market keys - Breaking changes ship under `/v2/`. The previous `/v1/` continues to work for at least 12 months after `/v2/` ships. - Deprecations announced via the changelog (RSS at https://parlay-api.com/changelog.rss) at least 90 days before any retirement. Changes to the schema log at https://parlay-api.com/changelog. Material changes get an email to active subscribers. ## 16.
