Too Long; Didn't Read
API is a JSON database of airports with their runways, navaids, countries, and regions information. The database is not 100% accurate because can have older data. Do not use it for a real flight or very sensitive applications. API service has one endpoint to get the airport information by its ICAO code. You can request data by the following URL:https://raw.github.com/epranka/airports-db/master/icao/<enter your ICAo>.json.
