An optional API key exists purely to raise allowances and unlock domain-scoped features. default: anonymous schemes: - type: none scope: All search, publishing, console and data-feed endpoints, the MCP server and the A2A interface work with no credential at anonymous allowances. - type: apiKey required: false obtained: Prove control of a domain with one DNS record via POST /claim then POST /claim/verify ("Verified" tier, free). The MCP server card declares authentication.required false with no schemes. delivery: Not documented publicly; the first-party CLI passes it as --key KEY. The OpenAPI declares no securitySchemes. grants: ~6x anonymous allowances, 30 days of rank history, unlogged searches, and the domain-scoped /private/entries surface (internal services visible only to that domain's key). Pro keys (contact) raise allowances ~5x further with metering readable at GET /me. notes: - GET /me answers without a key, returning the free-tier allowances rather than an error. - No OAuth/OIDC surface; /.well-known/oauth-authorization-server and /openid-configuration both 404.
