# Aviation METAR Weather

> Aviation METAR Weather is a paid API for AI agents from x402-toolbox.shablony-pro.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-29).

Retrieves real-time METAR (Meteorological Aerodrome Report) weather observations for aviation use, paid per-call via x402/USDC with no API key required.

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 aviation-metar-weather-b19e5587
```

Example prompt: Can you pull the current METAR weather report for KLAX so I can check the wind speed, visibility, and cloud ceilings before filing my flight plan?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time METAR aviation weather observations for a specific airport or aerodrome, especially in agent workflows where no pre-registered API key is available and pay-per-call micro-payment via USDC/Base is acceptable. Ideal for flight planning, dispatch, or aviation safety agents that need raw or parsed METAR data on demand without subscription overhead.

## Known failure modes

- Invalid or unknown ICAO station code returns an error or empty result
- Station not reporting (offline or no recent observation) may return stale or missing data
- Malformed schema parameter causes a 400-level error
- Payment failure or insufficient USDC balance prevents response
- Network timeout from upstream aviation weather data source

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

A JSON object containing the parsed or raw METAR data for the requested station, including fields such as wind speed and direction, visibility, sky conditions, temperature, dewpoint, altimeter setting, and present weather phenomena, along with payment confirmation fields (ok, paid).
