MCP server for Claude, Cursor and other AI agents
One API covers 450+ bookmakers and exchanges across 34 sports, in a single normalized JSON format. You get pre-match and live odds over REST or a WebSocket push feed, plus value bets, arbitrage detection, historical closing lines and bet settlement in the same API. There's also an MCP server, so AI assistants like Claude and Cursor can query odds directly.
Breadth and speed. Most odds APIs cover a few dozen bookmakers; we cover 450+, including regional books in Europe, Latin America and Asia. Live odds are pushed in milliseconds over WebSocket instead of polled. And the developer tooling is complete: official SDKs for Python, Node.js and R, a CLI, an MCP server, and docs with working examples.
Developers and data teams building sports betting products: odds comparison sites, betting tools and bots, trading and modelling teams, affiliates, and sports data apps.
Go for the API and WebSocket feed, PostgreSQL and Redis for storage and caching, Next.js for the website and dashboard, with SDKs in Python, TypeScript and R.
Built by Outlier AS in Norway out of frustration with odds data that was expensive, slow or limited to a handful of bookmakers. We started with the books our own products needed and kept adding, until one API covered 450+ bookmakers in one format, and opened it up to other developers in 2025.
