Learn how to configure OpenClaw (Clawdbot) to use NanoGPT's API for pay-per-use access to hundreds of AI models.

What is OpenClaw?

OpenClaw is an app that can connect to many of your personal apps (WhatsApp, Telegram, email, Slack, and more) and serve as an assistant or agent for automated tasks.

Step by Step Configuration

1. Download OpenClaw

Download and install OpenClaw from the official GitHub repository.

2. Get Your NanoGPT API Key

Go to https://nano-gpt.com/api and copy your API key.

3. Update Your OpenClaw Config File

Add the models attribute to your ~/.clawdbot/clawdbot.json file:

"models": {
  "mode": "merge",
  "providers": {
    "nano-gpt.com": {
      "baseUrl": "https://nano-gpt.com/api",
      "apiKey": "YOUR_NANOGPT_API_KEY",
      "api": "openai-completions",
      "models": [
        {
          "id": "claude-opus-4-5-20251101",
          "name": "Claude 4.5 Opus",
          "reasoning": false,
          "input": ["text"],
          "cost": {
            "input": 0,
            "output": 0,
            "cacheRead": 0,
            "cacheWrite": 0
          },
          "contextWindow": 200000,
          "maxTokens": 32000
        }
      ]
    }
  }
}

Important: Replace YOUR_NANOGPT_API_KEY with your actual API key from https://nano-gpt.com/api.

4. Restart the Gateway

Restart the gateway to apply your configuration changes:

openclaw gateway restart
