# StatePulse FAA Delay Checker

> StatePulse FAA Delay Checker is a paid API for AI agents from statepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Returns live FAA flight delay status for a given airport, including delay type, reason, and average delay duration.

## Facts

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 statepulse-faa-delay-checker-12f0d8ce -d '<json body>'
```

Example prompt: Are there any FAA delays at SFO right now — what's causing them and how long is the average wait?

## When to prefer this

Use this endpoint when you need real-time FAA-sourced delay data for a specific US airport, including the delay type, reason, and duration estimate. Prefer this over general flight status APIs when you specifically need FAA program-level delay intelligence (Ground Delay, Ground Stop, etc.) rather than individual flight status.

## Known failure modes

- Unknown or unsupported IATA code returns supported:false
- Airport not currently in FAA system may return no delay data
- Stale or unavailable FAA feed may reduce confidence to 'low'
- Invalid input format returns an error response
- Network timeout from upstream FAA data source

## How this service works

Queries the FAA public API for active delays, ground stops, and weather statuses for a US airport. Matches: air traffic control delays, US airport ground stops, flight weather delays, FAA flight restrictions, airport layout status.

## Output

A JSON object containing the IATA airport code, whether a delay is active (boolean), the reason for the delay (e.g. Weather, Volume, Equipment), the specific FAA delay type (e.g. Ground Delay, Ground Stop), the average delay duration in minutes, whether the airport is supported, and a confidence rating for the data.
