    All public read access to the CMS Open Payments data API is open and requires
    no authentication - no API key, no token, no account. The metastore catalog,
    search, datastore query, SQL, and download endpoints are all reachable
    anonymously over HTTPS. This was confirmed live against the API on the review
    date.

notes: >-
  The underlying DKAN platform exposes write and content-moderation endpoints that
  require HTTP Basic Authentication, but those are reserved for CMS data
  publishers and are not part of the public consumer surface documented here.
