Gutendex API not working for you?

  1. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  2. If calls fail only in the browser with a CORS error, Gutendex may not allow cross-origin requests. Call it from your server instead.
  3. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  4. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

Once a day our checker requests Gutendex's listed URL (https://gutendex.com/) and records whether it answers within 15 seconds.

The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.
