Overview
Claude Code is Anthropic’s official command-line AI programming assistant. You can connect it to Crazyrouter by configuring environment variables.

Verification
After launching, enter any question. If you get a normal response, the configuration is successful.
Claude Code uses the Anthropic native API format (/v1/messages), which Crazyrouter fully supports. Note that the Base URL should not include the /v1 suffix.
Make sure your token has Claude models enabled (e.g. claude-sonnet-4-20250514).
