OpenSky API
Live air traffic as an API, powered by the OpenSky Network — a community network of thousands of volunteer ADS-B/Mode-S receivers tracking aircraft worldwide in real time. This is live flight tracking, the FlightRadar-style picture of what is in the sky right now, distinct from static aircraft registries, airline directories, airport metadata and scheduled-flight status. /v1/flights returns every aircraft currently airborne inside a geographic bounding box (give the box as lamin/lomin/lamax/lomax in degrees, kept under roughly 20° latitude by 30° longitude), each with its ICAO 24-bit address, callsign, origin country, live longitude and latitude, barometric and geometric altitude, ground speed, true heading, vertical rate and transponder squawk — a real-time radar snapshot with the network timestamp. /v1/aircraft looks up a single aircraft by its 6-hex ICAO 24-bit address and returns its current live state (or airborne:false when it is grounded or out of receiver range). /v1/arrivals and /v1/departures list the flights that arrived at or departed from an airport (4-letter ICAO code such as EDDF Frankfurt or EGLL Heathrow) over the last N hours (1-48), each with callsign, the estimated airport at the other end and the first/last-seen timestamps. Ideal for live flight-tracking maps, aviation dashboards, geofencing and proximity alerts, spotting tools, and research into air-traffic patterns. Positions are in degrees, altitudes in metres and speeds in metres per second. Data from the OpenSky Network, free for non-commercial use — please credit OpenSky. Coverage depends on volunteer receiver density.
