# AviationAPIs ATIS Weather Lookup

> AviationAPIs ATIS Weather Lookup is a paid API for AI agents from aviationapis.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Returns current ATIS (Automatic Terminal Information Service) weather and operational data for a given airport by ICAO code.

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 aviationapis-atis-weather-lookup-fa81457a -d '<json body>'
```

Example prompt: What's the current ATIS for KSFO? I need the ATIS letter, temperature, dewpoint, and the full ATIS text.

## When to prefer this

Use this endpoint when you need structured, machine-readable ATIS data for a specific airport identified by its ICAO code, especially in aviation agent workflows for pre-flight briefing, situational awareness, or populating flight planning tools. Prefer this over raw METAR endpoints when you specifically need the ATIS letter, type (ARR/DEP), and full verbatim ATIS text as broadcast.

## Known failure modes

- Invalid or non-existent ICAO code returns an error
- Airport has no active ATIS (e.g. small non-towered fields)
- ATIS data temporarily unavailable or stale
- Malformed ICAO pattern (not exactly 4 alpha characters) rejected by schema validation
- Payment failure via x402 protocol results in 402 response

## How this service works

Pay-per-call aviation data APIs for AI agents, settled in USDC via the x402 protocol.

## Output

Returns a JSON object containing the full ATIS text string, ICAO code, ATIS letter identifier (e.g. 'B'), ATIS type (arrival/departure), temperature in Celsius, dewpoint in Celsius, the time the ATIS was observed, and when the data was fetched.
