OpenCat

OpenCat officially confirms BYOK only. The portal retains a one-click entry, while arbitrary Base URL fields remain unconfirmed.

Official source and verification​

This page was verified on 2026-07-13 against the official source for OpenCat 26.7.2. Official source. Compatibility is partial; BYOK documentation is not evidence of a verified custom address field.

One-click setup​

Sign in to the PopGo API keys page and open the action menu on the target Key row. Public documentation never creates or displays a link containing a Key. Open the Chat submenu, then choose OpenCat. After import, review the imported values inside OpenCat.

Manual setup​

No universal Base URL field is officially confirmed, so this page does not provide a fixed manual recipe.

Success check​

After import, send a new request with YOUR_MODEL. A saved Key by itself does not prove connectivity. Start a new test request with YOUR_MODEL. A normal response without authentication or address errors confirms the connection.

Common errors and recovery​

  • If the current release rejects import, stop guessing fields and use a verified OpenAI compatible client.
  • For a 401, paste YOUR_API_KEY again and remove surrounding whitespace.
  • For a 404, verify the Base URL level and make sure the client is not appending /v1 twice.
