The Federal Aviation Administration (FAA) is the United States civil aviation authority, an operating administration of the U.S. Department of Transportation. It regulates and certificates aircraft, airmen, airports and air carriers, operates the National Airspace System and its air traffic control, and issues the aeronautical information the entire U.S. travel and aviation chain runs on — NOTAMs, TFRs, charts, the 28-day NASR subscription, aircraft registration and airport data. It sits upstream of commercial travel distribution rather than inside it — the FAA sells no inventory and is not a GDS, NDC or channel participant, but every airline, GDS, OTA, flight-planning app and drone service supplier in the United States consumes FAA data as a source of truth. Its API posture is genuinely mixed and honest reporting requires saying so. The Airport Status Web Service and the Aeronautic Product Release API are published under a Creative Commons Zero licence, answer unauthenticated over HTTPS, and ship real OpenAPI 3.0.1 documents through a public Gravitee developer portal at api.faa.gov. Alongside them the FAA runs a CKAN 2.11.4 catalog and two ArcGIS Open Data hubs with DCAT-US 1.1 feeds and bulk CSV/GeoJSON/KML export. But the NOTAM API, the Air Carrier Pilot Records Database API and SWIM are gated — client_id/client_secret headers, operator eligibility restricted by regulation, or an executed SWIM agreement — and LAANC drone authorization is reachable only through FAA-approved UAS Service Suppliers, never directly.
Federal Aviation Administration publishes 4 APIs on the APIs.io network, including FAA Airport Status Web Service (ASWS), FAA Aeronautic Product Release API (APRA), FAA Air Carrier PRD API, and 1 more. Tagged areas include Travel, United States, Aviation, Airports, and Government.
The Federal Aviation Administration catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Federal Aviation Administration’s developer surface includes authentication, API reference, getting-started guide, signup flow, support, engineering blog, documentation, and 39 more developer resources.

host returns 404, so the route exists behind credentials. Access is via a client_id and client_secret issued from the
api.faa.gov developer portal. No public OpenAPI was published for this API in the portal's public catalog, so none was
harvested — and the API does not appear in that catalog at all, so it has no published plan. Re-verified 401 on 2026-07-28.
