Football-Data
Football-Data.org is a REST JSON API covering match fixtures, live scores, standings, squads, and lineups for Europe's top leagues and international tournaments, run by a small team that keeps its top competitions free "as this was the initial purpose to set up the project". Registering for a free API token is required for meaningful use (a live request confirmed working, rate-limited anonymous access is also possible); paid plans add more competitions and deeper historical/in-depth data. There's no client SDK -- just a documented header-based token and predictable REST paths.

- Get a key at the provider
- 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.
