## 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 x402pulse-airport-weather-forecast-72ceefca
```

Example prompt: What does the next 24 hours of weather look like at JFK — specifically wind, visibility, and any delay risk I should know about?

## When to prefer this

Choose this endpoint when you need a quick, human-readable decoded airport weather outlook for any airport worldwide, with flight-category and delay-risk context built in. Prefer it over raw METAR/TAF parsers when you want pre-interpreted period-by-period forecasts with hazard flags rather than raw coded strings. Not suitable for official flight planning or dispatch purposes — use certified aviation weather services for that.

## Known failure modes

- Unknown or invalid airport code returns an error — ensure IATA (e.g. JFK) or ICAO (e.g. KJFK) format is correct
- Weather data may be unavailable for very small or remote airfields
- Payment failure (insufficient USDC balance) returns a 402 error
- Rate limits or fair-use restrictions may apply without a Pro API key
- Forecast data freshness depends on upstream METAR/TAF provider availability

## How this service works

Pay-per-call data for AI agents: skill-ranked Polymarket traders, FDA drug and hospital data, oil markets, Wikipedia attention, travel delay risk and SEC filings, plus a daily Morning Brief. Paid in USDC on Base with x402, no API key or account.

## Output

A structured forecast broken into time periods covering the next 24-30 hours, each with wind speed, wind gusts, visibility, cloud ceiling height, FAA/ICAO flight category (VFR/MVFR/IFR/LIFR), a delay-risk rating, and flags for hazardous conditions such as low clouds, thunderstorms, snow, or strong gusts.
