Using OpenRouter with OpenClaw

What Is OpenRouter?

OpenRouter provides a unified API for accessing 100+ AI models from all major providers. One API key gives you access to Claude, GPT, Gemini, Mistral, Llama, and many more.

Why Use OpenRouter with OpenClaw?

• One key, all models — No need for separate API keys per provider
• Easy switching — Change models in one config line
• Fallback routing — Automatically try another model if one is down

• Cost management — Set spending limits across all models
