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
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

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

Free tierfrom $49/mo⚡ Streaming12 GitHub repos
53Score
What developers say
Odds and scores API with a free tier, offered directly and via RapidAPI. Very little real discussion: one old Stack Overflow question about a 404 and a few repos, including a sportsbook ingestion service and an odds API benchmark that lists it among rivals. No user opinion on quality or price is available.

What developers say
Aggregated odds API with broad bookmaker claims, used in side projects and sportsbook prototypes, and listed in MCP/agent tool collections. User feedback leans negative: live odds delayed by roughly 10 seconds or more, many UK bookmakers shown inactive, and Pinnacle support dropped in January 2026. Seen as an alternative to The Odds API and OpticOdds.

- + Many bookmakers and sports claimed
- + Easy to plug into prototypes

What developers say
Crowd-sourced sports database popular for hobby apps, tutorials, student projects and Plex metadata agents, with many wrappers in several languages. Praised as free and good for artwork. The free tier is tight, paid keys are needed for more, and developers report image and RapidAPI access problems and gaps in per-season artwork.

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.

Young odds aggregator pitched as a cheaper drop-in for The Odds API, with a free 1,000-credit tier, prediction-market books and MCP tooling. Nearly everything found is vendor-written posts, directory submissions or the founder's own repos. No independent user feedback on reliability, accuracy or support, so little is actually known.

Sports stats and Pinnacle odds API sold in monthly bundles with a 7-day trial. The only digest items are two repos from a developer's unrelated sports management system, not evidence of this API in use. No reviews exist, so nothing is known about quality or price.

What developers say
Odds API with broad bookmaker and sport coverage, used by developers for arbitrage tools, football research bots and benchmarks. Praised for global coverage, but users report 404/500 errors on some historical Betfair markets and limited NBA history starting late 2025, and some ask about gaps and latency. Compared with The Odds API and BoltOdds.

What developers say
Seen as the benchmark enterprise sports data supplier, used via trial keys in hobby projects, wrappers and tutorials. Developers repeatedly call it too expensive (thousands per month), opaque on pricing, sometimes unwilling to sell to small buyers, and not fast enough for live use. Common cheaper alternatives mentioned: SportsDataIO, Genius, Opta, Sportmonks.
Liked
- + Broad sport coverage and depth
- + Regarded as the reference provider
Watch out
