# Aviation Weather Multi-Airport METAR

> Aviation Weather Multi-Airport METAR is a paid API for AI agents from aviation-weather.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Returns current flight category, wind, and ceiling for up to 10 airports at once, ranked worst conditions first.

## 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 aviation-weather-multi-airport-metar-d0ed38d4
```

Example prompt: What are the current weather conditions — flight category, wind, and ceiling — at KJFK, KORD, KDEN, KLAX, and KSFO? Show me the worst airports first.

## When to prefer this

Choose this endpoint when you need to compare weather conditions across multiple airports simultaneously — up to 10 at once — and want them pre-ranked from worst to best flight category. It is more efficient than calling single-airport METAR endpoints in a loop and provides an aggregate summary verdict. Ideal for route planning, alternate selection, dispatcher situational awareness, or any scenario requiring a side-by-side comparison of current conditions at several stations.

## Known failure modes

- Invalid or unrecognized ICAO codes return those stations in the noReport array
- More than 10 ICAO codes supplied may be truncated or rejected
- Station with no recent METAR data returns null fields for that airport
- Network or upstream METAR source unavailability may set degraded=true
- Malformed icaos query parameter returns an error response

## How this service works

Current weather at up to 10 airports at once: flight category, wind and ceiling for each, worst first.

## Output

Returns a JSON object with an array of airports sorted worst-to-best, each containing station ID, flight category, wind direction/speed/gusts, ceiling in feet, visibility in miles, temperature in Celsius, and METAR age in minutes. Also includes an overall summary verdict, a degraded flag if some data is partial, and a list of any stations that could not be reported.
