# FAA NOTAM API

**Canonical:** https://apis.io/apis/faa/faa-notam-api/  
**Provider:** Federal Aviation Administration — https://apis.io/providers/faa/

**Documentation:** https://api.faa.gov/

FAA NOTAM API is one of 35 APIs that [Federal Aviation Administration](https://apis.io/providers/faa/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include NOTAM, Flight Information, Airspace, and Aviation. The published artifact set on APIs.io includes API documentation.

Notices to Air Missions retrieval API. Probe-confirmed live but gated — an unauthenticated GET returned HTTP 401 with the body {"message":"Unauthorized", "http_status_code":401} on 2026-07-28, while the bare external-api.faa.gov 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. This surface sits on the legacy side of the FAA's NOTAM modernization; see the NOTAM Management Service (NMS) entry.
