What developers say
Widely used for pulling bookmaker odds into fantasy tools, arbitrage scanners and betting models; many GitHub repos and tutorials build on it. Users like the free tier and breadth of markets and books. Complaints: modest refresh rate, historical odds limited to one day per call and gaps in snapshots, no prop results or match outcomes, some books paid-only.
Liked

- + Broad sports and bookmaker coverage
Watch out

6. Polymarket
Betting exchange
Prediction market exchange whose public Gamma API lists markets and events, including sports, without credentials; separate trading APIs and SDKs exist.

67Score
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.
Liked
- + Public market data without credentials
- + Large ecosystem of SDKs and bots
Watch out
- − Historical data hard to find, especially before 2024
- − Manual cross-venue event matching

What developers say
Commercial provider widely used for US sports, especially NFL fantasy tools that pull projections and stats from it. A free trial key makes prototyping easy. Developers on a budget repeatedly call it and Sportradar too expensive, and one user reported inaccurate season stats. Hobbyists look at JsonOdds or MySportsFeeds instead.

⚡ Streaming187 GitHub repos
41Score
What developers say
Enterprise odds feed supplier. Public discussion is scarce: an old suggestion thread and a hobbyist asking about sharing costs because enterprise-level data is steep. Recent repos and videos come from a World Cup hackathon built on its TxLINE feed, which shows interest but little independent opinion.
Watch out
- − Seen as expensive for individual modelers
