Multi-source historical betting data for backtesting. Prices are real book rows only. Result-only archives are labeled separately so modelers know exactly what is price history and what is match history.
Use the endpoint that matches the evidence you need. We keep price archives, closing lines, result archives, and forward line movement separate on purpose.
| Dataset | Endpoint | Best for | Guarantee |
|---|---|---|---|
| Point-in-time odds | /v1/historical/sports/{sport_key}/odds | TOA-style historical pulls | Real historical price rows inside the tier window. |
| Closing odds | /v1/historical/sports/{sport_key}/closing-odds | Pregame backtests | Last real price before commence where we have that archive. |
| Matches/results | /v1/historical/sports/{sport_key}/matches | Schedules, teams, scores, esports training sets | Each row exposes has_odds; result-only rows are not odds history. |
| Line movement | /v1/sports/{sport_key}/line-movement | CLV and before/after movement | Forward capture from our live tables, not a backfilled simulation. |
Current esports status: CS2, Dota 2, and Valorant have match/result archives plus forward Pinnacle price rows from May 2026 onward. They do not yet have deep historical odds movement for prior years.
Every claim a backtester wants to make rests on: are the prices real, do the games settle correctly, and is more than one source telling me the same thing? We pre-deduplicated and cross-tabulated for you.
Six independent feeds, none derived or interpolated. Every row is a real endpoint reading.
Top sports by row count. Each sport lists how many distinct sources we have prices from. Soccer leagues get the deepest cross-source coverage thanks to football-data.co.uk's bookmaker grid.

Each source is a distinct upstream. pinnacle and pinnacle_open are our own forward-going daily snapshots from the live Pinnacle endpoint. draftkings_espn is the DraftKings closing line as published by ESPN. nflverse_pbp is the canonical community NFL play-by-play archive (MIT licensed) covering 1999-2024. hoopr_nba is sportsdataverse's NBA betting-lines archive (MIT) going back to 2017. cfbd_consensus and the per-book cfbd_* entries come from collegefootballdata.com's /lines API across 11 NCAAF seasons. Each is an independent read of the market.

Same auth as the rest of the API. The endpoint is paginated; you can filter by date range, source, and sport.
