Connect OpenClaw to a free LLM API.

Who OpenClaw LLM API Setup is actually for

OpenClaw LLM API Setup is best for developers and power users who want model access inside tools, agents, scripts, and apps, not just a closed consumer chatbot tab.

• OpenClaw agents that need a custom hosted LLM provider.
• Users looking for a free API key to validate agent configuration.
• Long-running OpenClaw workflows that benefit from flat-rate pricing.

Keep the coding agent, change the model backend

The integration uses each tool's existing custom-provider support. Yolo-Auto supplies an OpenAI-compatible endpoint, API key, and public Qwen model without replacing the coding-agent interface.

Start with the free tier to verify the configuration. The same endpoint and model shape continue working when a flat-rate paid plan becomes a better fit for longer sessions.

Add Yolo-Auto to the agent's models.json

Copy the provider block, replace the API-key placeholder, and save it in the configuration for the OpenClaw agent you run.

{
  "providers": {
    "yolo-auto": {
      "baseUrl": "https://yolo-auto.com/v1",
      "apiKey": "ENTER_YOUR_yolo_KEY_HERE",
      "api": "openai-completions",
      "models": [
        {
          "id": "qwen3.8-27b",
          "name": "Qwen 3.8 27B",
          "contextWindow": 128000,
          "reasoning": true
        }
      ]
    }
  }
}

Keep the configuration private because it contains the API key.
