Gemini CLI

The Gemini CLI source does not confirm a third-party Base URL. Only the CC Switch route is documented as an implemented compatibility entry.

Official source and verification​

This page was verified on 2026-07-13 against the official source for Gemini CLI 0.50.0. Official source. Compatibility is partial; unconfirmed direct environment variables are not presented as official capabilities.

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. Choose CC Switch, then Gemini. After CC Switch imports the Gemini setup, do not look for direct variables that are not documented here.

Manual setup​

There is no officially confirmed manual third-party Base URL setup. This page does not invent environment variables.

Success check​

After CC Switch imports the setup, start Gemini CLI from a new terminal. A request with YOUR_MODEL must complete to count as success. Start a new test request with YOUR_MODEL. A normal response without authentication or address errors confirms the connection.

Common errors and recovery​

  • If CC Switch import fails, follow its recovery guide instead of trying an unverified variable name.
  • 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.
