Who it's for
Built for teams that trade on speed
Traders & market makers
Sharp lines and every square book in one socket. React to a move at Pinnacle or Novig before the rest of the market has re-priced.
Sportsbooks & DFS operators
Watch the whole market on every market you offer. Pull consensus, spot where you are off, and price your own board with confidence.
Affiliates, media & tooling
Best-price widgets, odds screens and alerts without running a scraper fleet. One key, one schema, every league.
Modelers & data teams
A clean, stable selection id per book, market and outcome. Timestamped changes you can replay into closing-line and lead-lag studies.
Developers
Integrate in an afternoon
A small, predictable REST surface for discovery and a WebSocket for everything that moves. JSON in, JSON out, bearer-token auth.
Push, not poll
Subscribe to a league or a list of games over one WebSocket. You get a snapshot, then only the selections that changed, with sequence numbers so gaps are detectable.
500 ms live, 1–2 s prematch
Live games update every 500 ms and prematch every 1–2 s. If a book stops reporting, its prices are pulled, so you are never trading on a stale number.
Stable identifiers
Game ids never change, even when a game goes live. Every selection has one id per book, market and outcome that you can key a database on.

Odds API questions, answered
A real-time sports betting odds feed: in-play and prematch prices from every major US sportsbook, the sharp offshore books, betting exchanges, prediction markets and DFS pick'em apps, normalized to one schema and delivered over REST and WebSocket. It is the same pipeline that powers the Prop Professor app.
500 ms for in-play games and 1–2 s for prematch.
45 sources: FanDuel, DraftKings, BetMGM, Caesars, Fanatics, BetRivers, Hard Rock, theScore, BetParx, BallyBet, Circa, Pinnacle, BetOnline, Bovada, Bet105, Prop Builder, Fliff, Rebet, Onyx Odds, SportZino and Courtside; the Novig, Prophet and 4cx exchanges; Kalshi, Polymarket, Polymarket US, Fanatics Markets and DraftKings Predictions; and PrizePicks, Underdog, Sleeper, Dabble, Betr, DraftKings Pick6, ParlayPlay, HotStreak, Boom and Chalkboard on the pick'em side.
NFL, NCAAF, CFL, NBA, WNBA, NCAAB, MLB, NPB, KBO, NHL, soccer, tennis, PGA, UFC and the major esports (LoL, CS2, Valorant, Dota 2, Call of Duty), plus futures boards for each major league. Every market a book prices is carried: moneylines, spreads and totals for every period, alternate lines, team totals, game props, the full player prop catalog and DFS pick'em lines.
Yes. Player props are the largest part of the feed, and PrizePicks, Underdog, Sleeper, Dabble, Betr, Pick6, ParlayPlay, HotStreak, Boom and Chalkboard lines are served in the same schema as the sportsbooks, so a prop at a book and the same prop at a pick'em app compare directly.
Both. REST endpoints handle discovery: leagues, sportsbooks, games, markets, a status check and a full odds pull. The WebSocket carries everything that moves: subscribe to a league or a list of games, receive a snapshot, then only the selections that changed, with sequence numbers so gaps are detectable.
