# StableTravel FlightAware Airport Weather Observations

> StableTravel FlightAware Airport Weather Observations is a paid API for AI agents from stabletravel.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13).

Retrieves current weather observations for a specific airport using FlightAware data, including temperature, wind, visibility, cloud cover, and flight rules.

## Facts

- Endpoint: GET https://stabletravel.dev/api/flightaware/airports/id/weather/observations
- Price: $0.004/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/stabletravel-flightaware-airport-weather-observations-bd8984cb
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_fKYhJq1k9N6JPeApov0D1

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 stabletravel-flightaware-airport-weather-observations-bd8984cb
```

Example prompt: What are the current weather conditions at KJFK right now — give me the temperature in Fahrenheit, wind speed, visibility, and whether it's VFR or IFR?

## When to prefer this

Use this endpoint when you need real-time aviation weather observations (METAR-style data) for a specific airport, especially when flight rules classification, wind conditions, or visibility are needed for flight planning or situational awareness. Prefer this over generic weather APIs when airport-specific ICAO codes and aviation-oriented output (flight rules, density altitude, raw METAR) are required.

## Known failure modes

- Invalid or unknown airport ICAO code returns an error or empty result
- Weather station offline or no recent observation available for the airport
- Invalid timestamp format causes query failure
- Rate limiting or payment failure returns 402 with payment required
- Nearby weather flag may not always return additional stations if none are close enough

## How this service works

Pay-per-request access to flights, award availability, hotels, activities, and transfers. No auth, no subscriptions.

## Output

Returns a JSON object with real-time airport weather observation data including timestamp, temperature, dewpoint, humidity percentage, wind speed and direction (with human-friendly description), visibility, barometric pressure, cloud layers, flight rules classification (VFR/IFR/MVFR/LIFR), conditions summary, density altitude, and raw METAR data string.
