balldontlie
balldontlie has grown well beyond its original NBA-only scope into a family of per-sport JSON APIs — NBA, WNBA, NFL, MLB, NHL, college football/basketball, MMA, PGA, soccer leagues, esports, and more — covering scores, player stats, betting odds, and player props. Every sport now requires a free API key rather than the anonymous access it once offered, with a $0/mo Free tier capped at 5 requests/minute per sport and paid All-Star/GOAT/All-Access tiers raising the rate limit and unlocking extended historical data. An OpenAPI spec and dashboard-issued keys back every product.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
