Simkl

Verified Jul 2026

Simkl is a movie/TV/anime tracking platform whose REST API mirrors watch-history and rating actions back to a user's Simkl account, alongside search endpoints for movies, TV shows, and anime by title. Every request needs a registered app's client_id (confirmed live: omitting it returns a client_id_failed 412 rather than a 404), and the Apiary-hosted docs — despite intermittently 502ing on individual requests — are the real, current source of truth.

Auth quickstart

  1. Sign up with the provider to get an API key.
  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
