VATSIM API
VATSIM, the Virtual Air Traffic Simulation Network, as an API — the largest online flight-simulation network, where tens of thousands of virtual pilots and air-traffic controllers fly and control in real time on flight simulators. This API exposes the live VATSIM network feed. /v1/pilots returns the pilots currently flying online, each with their live position (latitude, longitude, altitude, ground speed, heading), transponder, aircraft type and filed flight plan (departure, arrival, route, cruise altitude, flight rules); filter by airport (matching the departure or arrival ICAO, e.g. airport=EGLL) or by callsign prefix. /v1/controllers returns the air-traffic controllers currently online, each with callsign, radio frequency, facility (Delivery, Ground, Tower, Approach/Departure, Center), rating and logon time; filter by airport prefix (e.g. airport=KLAX matches KLAX_TWR, KLAX_APP), with an observers=true option. /v1/stats returns the network status — total connected clients and the number of pilots, controllers and ATIS positions online, with the snapshot timestamp. The network snapshot updates roughly every 15 seconds. Ideal for flight-simulation tools, live online-ATC and traffic maps, event and staffing dashboards, and community bots.
