## 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 flightaware-ef7a8f53
```

Example prompt: What's the weather forecast (TAF) at New Chitose Airport (CTS) right now? Show temperatures in Celsius and include nearby airport weather too.

## When to prefer this

Use this endpoint when you need official aviation TAF forecasts for a specific airport, especially for flight planning, departure/arrival weather checks, or aviation operations. Prefer this over general weather APIs when you need raw TAF strings and structured aviation forecast data tied to a specific ICAO airport code.

## Known failure modes

- Invalid or unknown airport ICAO code returns an error or empty result
- Airport does not have TAF data available (e.g. small aerodromes)
- Payment failure via x402 protocol returns 402 status
- Stale or unavailable TAF data if the meteorological source is delayed
- Invalid timestamp parameter format causes a bad request response
