# Saylor Innovations Data Desk – Airport METAR Weather

> Saylor Innovations Data Desk – Airport METAR Weather is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Returns decoded current METAR weather observations (flight category, wind, visibility, ceiling, altimeter, temperature, and raw report) for up to 5 ICAO airports in a single call.

## Facts

- Endpoint: GET https://saylorinnovations.com/api/aviation/metar?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-data-desk-airport-metar-weather-beafd500
```

Example prompt: What are the current METAR conditions at KJFK, KLAX, and KORD — give me the flight category, ceiling, visibility, wind, and altimeter for each?

## When to prefer this

Choose this endpoint when you need real-time, decoded METAR aviation weather (flight category, ceiling, visibility, wind, altimeter) for one to five specific airports by ICAO code. Ideal for pre-flight checks, dispatch decisions, or any agent task requiring authoritative current airport weather without parsing raw METAR strings yourself.

## Known failure modes

- Invalid or unknown ICAO code returns the code in a 'not_found' array with no observation
- More than 5 ICAO codes provided may result in an error or truncated response
- Station offline or no recent report may yield a missing or stale observation
- Malformed 'ids' query parameter returns an error
- Payment failure or missing x402 payment header results in a 402 response

## How this service works

Airport METAR weather - decoded current conditions, flight category (VFR/IFR), wind, visibility, ceiling, altimeter and raw report for up to 5 ICAO airports

## Output

A JSON object containing a count of observations returned, a timestamp of when the check was run, the data source, any airport codes not found, and an array of observation objects — each with station ID, name, coordinates, elevation, observation time, decoded wind, clouds, temperature/dewpoint in °C and °F, ceiling in feet, visibility in statute miles, altimeter in both inHg and hPa, flight category (VFR/IFR/MVFR/LIFR), weather phenomena, and the raw METAR string.
