API Reference
Every endpoint of the public API, generated from the code these docs were built from. To try a request against your own Librariarr, set the server’s baseUrl to its address, click Authorize and paste an API key; nothing you enter is stored. The same document is served by your instance at GET /api/v1/openapi.json and downloadable under Settings → Authentication → API Keys.
Your Librariarr has to allow the browser’s request, and from this site it allows only reads. It sends no CORS headers, so Try it out works here only for GET requests, and only when your reverse proxy adds CORS headers. A POST, PUT or DELETE from another site is refused with 403 whatever the proxy allows, because Librariarr rejects any write whose Origin is not its own address. To try writes, use the API docs page inside Librariarr (Settings → Authentication → API Keys → API docs), which has neither limit.
