Sports Betting API

The Sportsbook API for Real-Time Betting Odds

Q: What is a sportsbook API?

A sportsbook API gives your code the odds a bookmaker offers: events, markets and prices as JSON instead of a web page. Odds-API.io puts 450+ bookmakers behind one sports betting API, so you integrate once rather than once per sportsbook.

Q: How do I integrate a sportsbook API?

Get an API key, call /v3/events to find the matches you need, then /v3/odds or /v3/odds/multi for prices from the bookmakers you pick. Add the WebSocket feed when you need live updates without polling. The quickstart at docs.odds-api.io/quickstart covers the first request, and the Node.js, Python, PHP, Go and R SDKs handle the API key, retries and pagination for you.

Q: Is there a free sports betting API?

New free API keys are paused, and keys that already exist keep working. To start now, pick a paid plan: the Solo plan covers 2 bookmakers of your choice with 5,000 requests per hour on every sport and market, and you can cancel anytime. The /v3/sports and /v3/bookmakers endpoints need no key, so you can try a request first.

Q: Which bookmakers does the API cover?

450+ bookmakers, including Bet365, DraftKings, FanDuel, BetMGM, Betfair, William Hill and many more. That covers US sportsbooks, European bookmakers, Asian books and regional operators.

Q: Does the API support live/in-play betting odds?

Yes. Live odds are available over REST and over a WebSocket stream that pushes changes as they happen, which is what live betting apps and in-play arbitrage need.

Q: Can I use this API to build an arbitrage betting tool?

Yes. The /arbitrage-bets endpoint returns arbitrage opportunities across the bookmakers you choose, with the legs and optimal stakes already worked out. Customers use it for arbitrage scanners and market research tools.

Q: What sports and markets are covered?

34 sports, including football (soccer), NFL, NBA, MLB, NHL and tennis. Markets include moneylines, spreads, totals, player props and many others, depending on the sport and bookmaker.

A sportsbook API gives your code the odds a bookmaker shows its customers. Odds-API.io is a sports betting API with pre-match and live odds from 450+ bookmakers across 34 sports, in one JSON format over REST and WebSocket.

Sportsbook API Integration

One API key, plain HTTPS requests and JSON responses, in four steps.

1
Get an API key
Pick a plan and your key arrives by email. Every request sends it as the apiKey query parameter.
2
Find events
Call /v3/events with a sport and league to get event IDs, start times and status. /v3/sports and /v3/bookmakers need no key.
3
Fetch odds
/v3/odds returns the markets for one event from the bookmakers you choose. /v3/odds/multi takes up to 10 events per call.
4
Stream changes
Open the WebSocket feed to get odds updates as they happen. After a reconnect it replays what you missed.

Prefer a client library? There are official SDKs for Node.js, Python, PHP, Go and R, and an MCP server that lets Claude, Cursor and other AI tools query the API. Follow the quickstart for your first request or read the SDK guide.
