How this service works
Raw and decoded METAR (and optional TAF) for any airport ICAO code. Source: NOAA Aviation Weather Center. JSON.
Output
A JSON object containing the station ICAO code, raw METAR string, decoded fields including temperature in Celsius, wind speed in knots, and flight category (e.g. VFR, IFR, MVFR, LIFR), plus optional TAF forecast data.
Example use cases
Pre-flight weather briefing check
“Pull the current METAR for KSFO so I can see the raw report and whether it's VFR or IFR right now.”
Dispatch routing decision support
“What are the decoded METAR conditions at KJFK — I need temperature, wind speed, and flight category to decide if we can dispatch.”
Aviation chatbot real-time conditions
“Get me the latest METAR for EGLL including the raw string and decoded fields like visibility and wind.”

Endpoint
GEThttps://api.polyform.org/v1/weather/metar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time aviation weather (METAR/TAF) for a specific airport by ICAO code, especially when you want both the raw METAR string and structured decoded fields in one call. Prefer this over generic weather APIs when the consumer needs aviation-standard data (flight category, winds in knots, altimeter setting) rather than consumer weather data. The pay-per-call model with no API key makes it ideal for agent workflows that query airports infrequently or unpredictably.
Side effects
- Invalid or unknown ICAO code returns an error or empty result
- Station has not reported recently — stale or missing METAR data
- NOAA upstream outage causes lookup failure
- Malformed query parameters result in a 400-level error
- TAF not available for smaller airports
