# Citiview Aviation Weather (METAR + TAF)

> Citiview Aviation Weather (METAR + TAF) is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-14).

Returns decoded METAR observations and TAF forecasts for up to 10 ICAO airport codes, including flight category, wind, visibility, ceiling, clouds, temperature, and altimeter setting.

## Facts

- Price: $0.002/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 citiview-aviation-weather-metar-taf-be5464af
```

Example prompt: What are the current flight conditions at KJFK, KBOS, and KLGA — specifically the flight category (VFR or IFR), winds, visibility, and ceiling?

## When to prefer this

Choose this endpoint when an AI agent needs structured, decoded aviation weather (METAR + TAF) for one or more specific airports identified by ICAO code. It is ideal for pre-flight planning, dispatcher monitoring, or any workflow that needs machine-readable flight category, wind, visibility, and ceiling data without parsing raw METAR strings manually. Prefer it over general weather APIs when aviation-specific outputs (VFR/IFR categorization, altimeter, TAF) are required.

## Known failure modes

- Invalid or unrecognized ICAO code returns an error or empty result for that station
- More than 10 ICAO codes provided may result in truncation or rejection
- Station has no recent METAR observation (remote or non-reporting airport) returns no data
- Network or upstream weather data source unavailability causes timeout or 5xx error
- Malformed query parameter (e.g. wrong format) returns 400 bad request

## How this service works

Aviation weather for airports: latest METAR decoded (flight category VFR/IFR, wind, gusts, visibility, ceiling, clouds, temperature, altimeter) plus the TAF forecast, for up to 10 ICAO airport codes.

## Output

Returns a structured response per airport containing the decoded METAR (flight category VFR/IFR/MVFR/LIFR, wind direction and speed, gusts, visibility in statute miles, ceiling height, cloud layers and coverage, temperature and dewpoint, altimeter setting) plus the raw and interpreted TAF forecast for the requested ICAO codes.
