# FAA US Airport Delays & Closures API

> FAA US Airport Delays & Closures API is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-09).

Returns current FAA ground delay programs, ground stops, arrival/departure delays, and closures for US airports, optionally filtered by IATA code.

## Facts

- Endpoint: POST https://api.vextorium.com/aeropuertos-eeuu-estado-pago?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-09
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/faa-us-airport-delays-closures-api-b4b55bdf
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_6dAQh0JpBwY0p-54-CTaZ

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability faa-us-airport-delays-closures-api-b4b55bdf -d '<json body>'
```

Example prompt: Are there any active FAA delays or ground stops at JFK right now — and if so, what's the reason and how long are they expected to last?

## When to prefer this

Use this endpoint when you need real-time FAA operational status for US airports — specifically ground delay programs, ground stops, and closures with reasons and durations. Prefer this over general flight status APIs when the user needs the authoritative FAA source for systemic airport-level disruptions rather than individual flight tracking.

## Known failure modes

- Invalid or unknown IATA code returns empty or null airport field
- FAA data feed temporarily unavailable may return stale or null data
- No incidents returns sin_incidencias: true with empty incidencias array
- Malformed request body (wrong bodyType or missing required fields) returns error
- Rate limiting or payment failure returns HTTP 402

## How this service works

Current delays and closures at US airports from the FAA: ground delay programs, ground stops, arrival/departure delays and closures with reason and duration; filter by IATA code (JFK, LAX, ORD...).

## Output

Returns a JSON object with: total number of incidents, data source (FAA), airport code, last updated timestamp, a boolean indicating no incidents, and an array of incidents each containing incident type (e.g. ground delay program, ground stop, arrival/departure delay, closure), reason (e.g. weather, volume, staffing), airport code, average delay time, and maximum delay time.
