From public data checked . How we know
Choose BALLDONTLIE if you…
Sports data API
Best for: Developers building sports apps, dashboards or AI-assisted projects who want stats, box scores and odds for many leagues from one REST API with a free entry plan.
- ✓ want to start on a free tier
- ✓ need commercial use allowed in the public terms
- ✓ build a betting product and need that allowed in the public terms
- ✓ care most about what developers report in practice
Not ideal for: Companies that want to offer a competing sports-data API or feed built on its data, which the terms forbid.
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.

- ✓ need Motorsport
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.
