notes: >-
  Every NASA Open API is authenticated with a single api_key query parameter on
  api.nasa.gov (and images-api.nasa.gov for the Image and Video Library, whose
  read endpoints are open). The specs model api_key as a required query parameter
  rather than a formal OpenAPI securityScheme, so mechanical derivation finds no
  scheme; this profile is authored from the parameter + published docs. There is
  no OAuth, OIDC, mTLS, or scope surface. DEMO_KEY is a shared public key for
  exploration (see sandbox/). Higher rate limits require emailing api@nasa.gov.
