summary: >-
  Keyless public API. There is no authentication of any kind — no API keys, no OAuth, no accounts.
  Access is anonymous over HTTPS and throttled per client IP address.
schemes:
  - id: anonymous
    type: none
    description: No credential required. Call https://flatin.pt/api/v1 or connect an MCP client to https://flatin.pt/mcp directly.

notes:
  - The MCP server at https://flatin.pt/mcp is also anonymous; no OAuth authorization-server or protected-resource metadata is served (both /.well-known probes returned 404).
  - Every successful JSON answer carries an attribution field that must be displayed next to the numbers (a licence condition, not an auth condition).
