Nearest airport to coordinates API

The closest airports to a lat/lng from the OurAirports open dataset (~75k airports): name, IATA/ICAO codes, type, and great-circle distance. The dataset is the moat — an agent doesn't know airport coordinates. Answers 'nearest airport to these coords', 'closest airport', 'what airport serves this location'.
