OpenCat

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

Before configuring​

  • This page uses placeholders only. Copy the real Key from PopGo API keys and the model from models and pricing.
  • One-click setup is for software that is already installed and has registered its protocol handler. Allow the browser to open the external app when prompted.
  • For manual setup, save one minimal Provider first. Enable streaming, tools, or multi-model routing only after the first request succeeds.

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.

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.
