Database or API of icao24 (aircraft ID) information

Question

Is anyone aware of a database, API, or other source of data on icao24?

I want to be able to give an icao24 (from an OpenSky API), and get some information as much information as possible about the associated aircraft.

Answer 1

They do have an aircraft database available right on the website (also for download): https://opensky-network.org/aircraft-database

Otherwise, the usual suspects are there for individual research but no API: https://flightradar24.com/data, FlightAware, Radarbox etc.
