description: >-
  The NutrientsDB Sample API requires NO authentication. This is an explicit, documented posture,
  not an omission: the docs page states "No authentication" alongside "HTTPS" and "CORS enabled",
  and the OpenAPI declares no components.securitySchemes and no security requirement on its single
  operation. Verified by an anonymous live call that returned 200 with data. There are no API keys
  to issue, no OAuth surface, no scopes, and therefore no scopes/ artifact for this provider.

    notes: >-
      Wildcard CORS with no credentials makes the endpoint directly callable from browser and agent
      runtimes with no proxy or key-broker in front of it.
  scope_of_access: >-
    The keyless endpoint exposes only the public 1,000-food sample. The full ~2.9M-food NutrientsDB
    dataset is not behind an authentication wall on this API — it is not exposed by this API at all.
    It is sold as a one-time-license downloadable dataset for local use, so the commercial boundary
    is a delivery boundary, not an auth boundary.
