Use API to find flight number of given ICAO hex?

I have a Piaware setup and I’m writing a Python script that collects some data about flights in the neighbourhood. In aircraft.json I find the ICAO hex of an aircraft. Is it possible to use a free API service to get a flight number (for example UA2777) for a given ICAO hex (for example A13DE2)?


The ident/callsign the aircraft transmits will often tell you this, when present.

https://flightaware.com/live/modes/ABCDEF will redirect to FlightAware’s current flight page for ICAO address ABCDEF at the time (SkyAware provides this link), though this is for humans, not scripts.
