## 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 2s-aviation-taf-terminal-aerodrome-forecast-api-520285d5
```

Example prompt: Can you pull the current TAF forecasts for KATL and KORD so I can check the aviation weather before my flight?

## When to prefer this

Use this endpoint when you need authoritative, real-time Terminal Aerodrome Forecast data directly from NOAA for one or more airports by ICAO code, especially when no API key or signup is desired and pay-per-call USDC pricing is acceptable. Prefer over scraping aviationweather.gov directly or using general weather APIs that don't provide aviation-specific TAF format.

## Known failure modes

- Invalid or unknown ICAO code returns empty items array with total 0
- Missing required 'ids' query parameter returns a 400-level error
- Temporarily unavailable NOAA upstream source may return ok: false or empty data
- Malformed comma-separated IDs may result in partial or no results
- Network or payment failure returns HTTP 402 or 5xx

## How this service works

Terminal Aerodrome Forecast (TAF) for one or more airports — the official aviation forecast issued for an airport (~24–30h ahead). Pass ids = comma-separated ICAO station ids (e.g. KATL). Returns the raw TAF text + issue time. Source: NOAA Aviation Weather Center (keyless). For current conditions use aviation.metar.

## Output

Returns a JSON object with an array of TAF items, each containing the raw TAF string, airport name, ICAO station code, and issuance timestamp, plus source metadata (provider: NOAA Aviation Weather Center, license: US Government public domain). Total count of results is also included.
