OpenRouter

OpenRouter provides a unified API that routes requests to many models behind a single endpoint and API key. It is OpenAI-compatible, so most OpenAI SDKs work by switching the base URL.

CLI setup

openclaw onboard --auth-choice apiKey --token-provider openrouter --token "$OPENROUTER_API_KEY"

Config snippet

{
  env: { OPENROUTER_API_KEY: "sk-or-..." },
  agents: {
    defaults: {
      model: { primary: "openrouter/anthropic/claude-sonnet-4-5" },
    },
  },
}

Notes

• Model refs are openrouter/<provider>/<model>.
• For more model/provider options, see /concepts/model-providers.
• OpenRouter uses a Bearer token with your API key under the hood.
