  Fetched anonymously from the FAA's Gravitee APIM developer-portal REST API on
  2026-07-28 (HTTP 200 for all five APIs). These are the FAA's own published
  subscription plans, not an inference.
summary: >-
  Every FAA API is free. There is no paid tier, no metered billing and no
  commercial plan anywhere in the FAA estate — the agency is a US federal
  regulator publishing public data, and the two flagship open APIs carry a
  Creative Commons Zero (CC0) licence in their OpenAPI. What the portal DOES
  publish is a real subscription model: two APIs run a KEY_LESS plan (call them
  with no credential at all) and three run an API_KEY plan whose subscription
  requires MANUAL approval by the FAA API owner. So the gate is eligibility and
  approval, never money.

not_covered_by_a_portal_plan:
- api: FAA NOTAM API (external-api.faa.gov/notamapi/v1)
  reason: >-
    Not present in the Gravitee portal catalog at all, yet the route answers 401
    to an unauthenticated call. Credentials are issued outside the published plan
    model.
- api: FAA NOTAM Management Service (NMS) API
  reason: >-
    Access is requested by email to notams@faa.gov per https://nms.aim.faa.gov/.
    No plan, price or quota is published.
- api: SWIM / SWIM Cloud Distribution Service
  reason: >-
    Governed by an executed FAA SWIM agreement through the SWIFT Portal, and by
    request to Data-To-Industry@faa.gov for CDM, TFMS Request/Reply and TFMS
    International Data Provider. Not a portal plan.
- api: LAANC
  reason: Available only through FAA-Approved UAS Service Suppliers, never directly.
- api: CKAN data catalog, AIS and UDDS ArcGIS Open Data hubs, TFR list, NAS status feed
  reason: Open platforms outside the API gateway; no plan and no credential.
