Claude Code CLI

Configure Anthropic's official CLI agent to route through RayRouter.

Method 1 — Environment Variables (per session)

export ANTHROPIC_BASE_URL="https://api.rayrouter.com"
export ANTHROPIC_API_KEY="<YOUR_API_KEY>"
claude

Method 2 — Config File (persistent)

Create or edit the settings file at:

Linux / macOS:~/.claude/settings.json

Windows:%USERPROFILE%\.claude\settings.json

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.rayrouter.com",
    "ANTHROPIC_AUTH_TOKEN": "<YOUR_API_KEY>",
    "ANTHROPIC_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-v4-flash[1m]",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "CLAUDE_CODE_EFFORT_LEVEL": "max"
  }
}

How it works under the hood:

Anthropic's Claude Code CLI uses ANTHROPIC_BASE_URL to send requests. By routing to /v1/messages, all messages are automatically matched against active providers in RayRouter and settled seamlessly against your virtual smart wallet balance.
