note: >-
  Derived from probed RFC 8414 / RFC 9728 discovery documents and observed 401 responses,
  not from an OpenAPI — 1up publishes no OpenAPI. Two distinct auth surfaces exist and they
  are not the same thing: the public MCP server (OAuth 2.1) and the platform REST host
  api.1upapi.com (undocumented, token-authenticated, Django REST Framework).

  note: >-
    Not part of a public developer program. The base URL and Authorization-header behaviour
    are recorded here only because 1up's own published PyPI package names them; there is no
    public reference, no published spec and no self-service key issuance. The host answers
    an anonymous GET /api/v1/ with HTTP 401 and the Django REST Framework body
    {"detail":"Authentication credentials were not provided."}. Tokens are Auth0-issued
    (audience https://1up-app.us.auth0.com/api/v2/) and obtained via `1up-mcp auth login`.
