OpenRouter HTTP API

Create a key from the API keys page (or manage existing keys from key settings). Give it a name and optionally set a credit limit. Use the resulting key as a Bearer token in Authorization.

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.

Create a management key from the Management API Keys page: click Create New Key and complete the flow. This key is only for administrative key-management endpoints under /api/v1/keys, not for inference/completions.
