Overview

TheRundown API provides comprehensive sports data through a 20+ sportsbook-and-exchange integration roster. Live API coverage includes DraftKings, FanDuel, BetMGM, Pinnacle, Kalshi, and Polymarket; Novig and ProphetX are the next exchange integrations and become queryable when their feeds publish. Every published source uses one schema. Coverage spans 550+ market types, futures and outrights, live scores, play-by-play with live game state, game schedules, team and player statistics, and historical line data across major North American and international sports leagues.

​
What you can build

  • Live odds screens — Real-time moneylines, spreads, and totals from every book we carry, over REST or WebSocket
  • Cross-venue comparison — Sportsbook and exchange prices on the same events, in the same format (Kalshi and Polymarket today; Novig and ProphetX when their feeds publish)
  • Futures boards — Championship, division, and award futures priced across sportsbooks and exchanges — see the Futures guide
  • Live game trackers — Play-by-play with running scores and live game state (count and base runners, down and distance, possession), streaming per play over WebSocket
  • Line movement trackers — Historical price data with charting support, opening and closing lines
  • Player prop tools — Props, alternates, and combo markets across 550+ market types
  • Team and player stats — Season and game-level statistics, with live box-score deltas over WebSocket
  • Sports data apps — Complete sports data platform with scores, odds, stats, and schedules

​
Real-time delivery

Every plan can poll efficiently with delta endpoints. Real-time tiers (Ultra and above) add WebSocket streaming — markets, scores, plays, stats, futures, and live channels over a single connection. Odds updates are generally sub-second on major books; they come straight from the sportsbooks’ own feeds. See the WebSocket reference for protocol details and per-plan connection and subscription limits.

​
Supported sports

Soccer coverage includes MLS, EPL, Ligue 1, Bundesliga, La Liga, Serie A, UEFA Champions League, UEFA Euro, FIFA, J-League, and UEFA Europa League. Play-by-play coverage spans MLB, NBA, WNBA, NCAAB, NFL, NCAAF, NHL, and soccer, with per-play player attribution rolling out progressively. See Sport IDs for the full list and per-sport feature matrix.

​
V1 vs V2

V2 (recommended) uses a market-based data model where each odds type is a “market” with participants, lines, and prices. This is more flexible and supports player props, alternates, and new market types. V1 (legacy) uses a flat line-based model with separate moneyline, spread, and total objects. V1 is still supported but new features are V2-only.
