## 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 financial-data-x402-airport-check-faa-advisories-ecd019ae
```

Example prompt: Are there any active FAA advisories or ground delay programs at Denver International (DEN) right now?

## When to prefer this

Use this endpoint when you need real-time FAA airport advisory and ground delay program data for a specific airport without managing API subscriptions or keys. Ideal for aviation-aware agents, travel assistants, or automated monitoring workflows that pay per query via USDC on Base or Solana using the x402 protocol.

## Known failure modes

- Invalid or unsupported IATA code returns an error or empty advisories array
- Payment failure via x402 results in HTTP 402 response and no data
- Airport not currently monitored by FAA advisory system may return no advisories
- Network or upstream FAA data outage may cause stale or unavailable data

## How this service works

Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.

## Output

Returns a JSON object with the airport's advisory status (e.g. 'advisory' or 'normal'), the IATA code, and an array of active advisories each containing the category (e.g. 'Ground Delay Programs'), reason (e.g. 'thunderstorms'), average delay duration, and maximum delay duration.
