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.

What developers say
Long-popular free NBA stats API, now covering NBA, NFL, MLB and EPL with a free tier and paid keys. Beginners use it for tutorials, React projects and portfolio apps; betting and fantasy builders pair it with odds feeds. Recommended as an alternative to nba_api and API-Sports. Little discussion of reliability or pricing.
Liked

What developers say
Widely used paid football data API for side projects, dashboards and betting models, with many wrappers and GitHub repos. Users like the stats depth and reasonable price versus Opta or Sportradar, but call it pricey for hobby use, say premium odds lack player props, and report unreliable live data and sales or custom-plan frustrations.
Liked
- + Solid football stats and many leagues
- + Cheaper than Opta or Sportradar
Watch out
- − Pricey for side projects
- − Live data felt unreliable or slow

4. 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
Very widely used for football side projects, prediction models and live-score apps, praised for broad league coverage, decent docs and low price (about $19/month).

65Score
What developers say
Esports data provider with REST API covering LoL, CS, Dota and others. Seen in dev questions for upcoming-match apps and a few GitHub wrappers and bots. Community remarks are sparse and mostly old: one user notes odds are paywalled, and it appears as one of few usable esports APIs. No real user verdict on quality or pricing.
Liked
- + One of few dedicated esports APIs
- + Used for LoL and CS match schedules
Watch out

64Score
What developers say
Popular free-tier choice for hobby football projects: World Cup predictors, score trackers, league tables, and a fallback when API-Football quota runs out. Developers like the free key and simple docs. Complaints: free tier gives fixtures and final scores but no shots, xG or lineups, history starts around 2019, and a low request rate.
Liked
- + Free API key good for fixtures and results
- + Frequently chosen for side projects
Watch out
- − No detailed match stats or xG on free tier
- − Limited history before 2019

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.
Liked
- + Free trial key for prototyping
- + Strong US sports and fantasy projections coverage
Watch out
- − Too expensive for bootstrapped projects
- − Reported inaccurate player season stats

9. Betfair Exchange API
Betting exchange
Betfair's developer API for its betting exchange: market prices, order books and bet placement. Free delayed key for development; live key needs an approved application and a one-off fee.
Free tierfrom £299 one-time30 discussions272 GitHub reposMixed
60Score
What developers say
The standard exchange API for betting bots and trading tools, with long-standing wrappers and many automation projects. Users complain about restricted access: regional blocks (Brazil), certificate login hurdles, and a reported live-key fee of around 500 pounds. Many seek third-party feeds or historical data instead.
Liked
- + Real exchange prices and bet placement
- + Mature community wrappers
Watch out
- − Blocked in some countries

What developers say
Real-time sports odds API for US sportsbooks with +EV and arbitrage endpoints, launched in 2026 with a free beta tier. Material is mostly the founder's own launch posts plus one user using it for an arb tool and praising its sharp-book coverage versus The Odds API. Repos are few; sample data, R client and MCP server exist.

What developers say
Long-standing free CSV archive of results, match stats and bookmaker odds, the default starting point for football modelling and used by thousands of GitHub projects. Users value the free historical odds, but say league coverage is limited (few lower or secondary leagues) and files are downloads, not a live API.
Liked
- + Free historical results and odds
- + Widely used in models and scrapers

12. PropLine
Odds API
Player-prop and game odds from 100+ sportsbooks and exchanges across 73 sports, with graded prop results, line history, cross-book +EV and webhook or websocket alerts. Billed per request, compatible with The Odds API format.
Free tierfrom $9/mo⚡ Streaming20 GitHub repos
59Score
What developers say
Per-request-billed player-prop and odds API that mimics The Odds API format and grades props against box scores. Digest holds only a Show HN post, directory import and the vendor's own SDK, MCP and tool repos. No independent user opinion on accuracy, limits or cost, so little is known.

What developers say
Per-event-priced odds API with props and alternate lines, mentioned by algobetting users comparing it with The Odds API and similar vendors. Reported weaknesses: inconsistent or missing Fliff odds, only main markets for Australian books, and upstream errors in one project. Several wrappers, MCP servers and dashboards build on it.
Liked
- + Props and alternate lines included
- + Considered alongside The Odds API
Watch out
- − Fliff odds inconsistent or missing

What developers say
Cheap feeds for the four major US leagues, with wrappers and many hobby and fantasy repos. Most early praise is the owner's own pitch. Later users report unresponsive support and missing college basketball data, and a 2021 asker found no college or soccer coverage.

15. Highlightly
Sports data API
Sports API combining live scores, fixtures, standings, lineups, player stats, odds and predictions with video highlight clips. Covers football, US leagues, cricket, rugby, volleyball and handball.
Free tierfrom $12.49/moLive data43 GitHub repos
57Score
What developers say
Sports API pairing scores and stats with video highlights. Little independent opinion exists: a few freelance requests to build sites on it, one repo issue comparing it with cheaper providers for backtesting, and AI-generated football video channels crediting it as a data source. Adoption seems modest and unproven.
