Spire Aviation Beta Events Stream API offers a continuous data flow of all significant events taking place over a flight's lifecycle.
In contrast to the Spire Flights Live API, this stream can be consumed in its entirety for all global flight events observed in real-time or, it can be called using a parameter for a given aircraft, flight or event type.
The Events Stream API benefits from extensive development to Spire Aviation’s flight detection algorithm to condense hundreds of millions of ADS-B messages in real-time for a rich combination of flight, aircraft, airline, airport and schedule metadata in one JSON object per flight observed flight event.
The ADS-B capable aircraft transponders emit several messages with different bits of information several times per second. Spire’s satellites collect these messages that are processed into a Target Update, which corresponds to an update for each ICAO address for each 5-second interval.
