Find airports near any GPS coordinate
Pass lat, lon, and radius_km to the Airports endpoint — get back all airports in range, sorted by distance. Built for departure-airport pickers, smart assistants, and proximity-aware travel apps.
The NearBy API for Travel & Aviation Apps
No geocoding step, no custom distance math. Add three parameters to the Airports endpoint and get a ready-to-use proximity list — with IATA codes, passenger counts, and exact distances.
GPS-Native Radius Search
Pass any WGS84 lat/lon coordinate and a radius in kilometres. The API pre-filters airports with a bounding box, then sorts by exact Haversine distance — so the nearest airport is always first.
Major Airports Filter
Add major_only=1 to restrict results to large international airports — ideal for booking UIs where small airfields aren't relevant.
distance_km Field
Every airport object in the response includes a distance_km field — the great-circle distance from your query point, rounded to two decimal places.
Fast & Paginated
Default limit of 50 results per page. Use limit and offset to paginate through large radius results consistently.
Full Airport Data
Results include IATA, ICAO, name, type, coordinates, country code, and annual passenger counts — the same rich Airport object as the standard Airports API.
Nearest airport in one line
Add lat, lon & radius_km — get back sorted airports with distance.
