Stations

Stations in our API represent physical aviation and weather locations, including airports, heliports, seaplane bases, gliderports, and dedicated weather reporting stations.

Each Station is identified by a four-character alphanumeric ICAO code that uniquely designates a location worldwide. The first one or two characters indicate the country or region, while the remaining characters identify the specific station. For example, Heathrow Airport in London uses the ICAO code EGLL, while John F. Kennedy International Airport in New York is identified as KJFK.

Station Response

Station results are available in one structured JSON response format. The response is in key-value pairs for easier processing.

Note

You do not need to include/raw,/short, or/decodedin the endpoint URL for Stations.
