From public data checked . How we know
Choose Polymarket if you…
Betting exchange
Best for: Developers wanting free public market and event data, including sports, from a prediction market exchange without credentials.
- ✓ want to start on a free tier
- ✓ value a large open-source ecosystem of wrappers and examples
- ✓ care most about what developers report in practice
Not ideal for: Sports-only data needs or bookmaker odds; it is a prediction exchange and sports endpoints and rate limits were not verified.
What developers say
Widely used as a free, no-key source of prediction-market prices (Gamma and CLOB APIs) for sports arbitrage bots, wallet trackers and odds aggregators, with many GitHub clients and MCP servers. Users note thin or missing historical data and the need to match events across Kalshi and sportsbooks; live-score speed is a concern.

No clear advantage in the public data; compare coverage on your own use case.
What developers say
UK betting exchange with an account-holder API used by a few older Python wrappers. Recent chatter treats it as a minor option next to Betfair and Matchbook, with notably lower liquidity, and aggregators list its lay prices. There is little hands-on feedback on API quality, so little is known beyond liquidity worries.
