xeno-canto
xeno-canto is a global, community-built library of wildlife sound recordings — overwhelmingly birds, with growing collections of bats, grasshoppers, and frogs — searchable by species, location, recordist, or sound type through its REST API. API v2 has been fully retired server-side (a live call now returns a JSON error directing callers to v3), and v3 requires a personal key from a free xeno-canto account, confirmed via a live 401 response reading "Missing or invalid 'key' parameter." It remains free to use, and CORS is open: both a GET call and a separate OPTIONS preflight echo the requesting Origin back with credentials allowed.

- 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.
