echo 'export ANTHROPIC_API_KEY=sk-xxx' >> ~/.bashrc
source ~/.bashrc

$env:ANTHROPIC_BASE_URL = "https://crazyrouter.com"

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).
