From public data checked . How we know
Choose SportsDataIO if you…
Sports data API
Best for: Developers and businesses wanting one vendor for US-centred scores, stats, odds, projections and fantasy data across many leagues, evaluated first with a free trial.
- ✓ need American football, Basketball, Baseball
- ✓ value a large open-source ecosystem of wrappers and examples
- ✓ care most about what developers report in practice
Not ideal for: Buyers who need public price lists or self-serve checkout; production access needs a sales conversation.
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.
Choose API-Tennis if you…
Sports data API
Best for: Tennis-only apps and models that need fixtures, livescores, head-to-head and odds from a fixed monthly plan with a trial.
- ✓ want a 14-day free trial before paying
- ✓ want WebSocket push instead of polling
Not ideal for: Projects that need other sports, a free tier, or business accounts: accounts are individual and not shareable.
What developers say
Tennis API with livescores, fixtures, odds and WebSocket, used in around thirty small GitHub projects and tutorial apps. Users describe it as pricey compared with RapidAPI options, and one developer found it only a results feed, with no draw sheet, seeds or bracket positions. Compared with Matchstat; little other direct feedback.
