tip

• Cost tracking — See exactly what OpenClaw spends across all models
• Model routing — Switch between Claude, GPT-4, Gemini, Bedrock without config changes
• Virtual keys — Create keys with spend limits for OpenClaw
• Logging — Full request/response logs for debugging
• Fallbacks — Automatic failover if your primary provider is down

  <Step title="Run onboarding">
    ```bash}
    openclaw onboard --auth-choice litellm-api-key
    ```

    For non-interactive setup against a remote proxy, pass the proxy URL explicitly:

    ```bash}
    openclaw onboard --non-interactive --auth-choice litellm-api-key --litellm-api-key "$LITELLM_API_KEY" --custom-base-url "https://litellm.example/v1"
    ```

  <Step title="Start LiteLLM Proxy">
    ```bash}
    pip install 'litellm[proxy]'
    litellm --model claude-opus-4-6
    ```
  </Step>

  <Step title="Point OpenClaw to LiteLLM">
    ```bash}
    export LITELLM_API_KEY="your-litellm-key"

    openclaw
    ```

    That's it. OpenClaw now routes through LiteLLM.
