OddsLink

Kalshi price at 52 cents is not 52 cents after the fee. OddsLink API now returns every exchange and prediction market price after its published taker fee: Kalshi, Polymarket, Novig, Betfair, Matchbook and more, next to sportsbook odds in one call.

Esports odds are now in the OddsLink API: CS2, League of Legends, Dota 2 and Valorant. Match odds, map handicaps, map totals and per-map lines from the books that price them, in one JSON format. On every plan, Free included.

OddsLink now has historical odds! Opening and closing lines for every game back to 2014. Pinnacle included. Same API, same event ids, same JSON as live.

Give Claude real odds instead of a guess. The OddsLink MCP server has 7 tools: list_sports, list_events, list_markets, list_bookmakers, get_odds, get_props, get_history. Add it to Claude, Cursor or Codex and ask in plain English.

Building a +EV screen, an arbitrage scanner or a middles finder? The maths fits in a few lines. Most of the work is joining books: matching fixtures, market keys and team names. OddsLink does that part and hands you one JSON shape.

OddsLink is a sports odds API. Sportsbooks, exchanges and prediction markets come back in one JSON shape, with one id per fixture across every book. Moneylines, spreads, totals, periods, player props, in-play, history, a WebSocket feed and an MCP server for AI agents.
