POST /v1/airport/nearest
unprobed
Up to 5 airports with scheduled service nearest a named place, ranked by real road drive time (never a straight-line guess), with IATA and ICAO codes. airport_size 'large' keeps large airports only. Within 300 km; none in range is a 422; airports with no road route are left out. OpenStreetMap routing, OurAirports data, worldwide.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
