How this service works
Nearest airports to a latitude and longitude with distance, bearing, type and codes; filter by size or scheduled service.
Output
A JSON array of airports sorted by distance from the query point, each entry containing the airport name, IATA code, ICAO code, type (large/medium/small/heliport etc.), distance in km and nautical miles, bearing, latitude, longitude, elevation, country, region, and whether scheduled service is available. Also includes a summary and the echoed query parameters.
Example use cases
Flight planning from remote site
“I'm at coordinates 34.0522 latitude, -118.2437 longitude — can you find the nearest airports within 100 km that have scheduled commercial service, showing just large and medium ones?”
Emergency diversion airport lookup
“Give me up to 25 airports of any size within 500 km of lat 48.8566, lon 2.3522, sorted by distance — I need their IATA and ICAO codes too.”
Travel logistics for a new office location
“We're opening an office at latitude 1.3521, longitude 103.8198 — what are the nearest airports within 150 km, and are any of them large international airports with scheduled flights?”
Technical details
Endpoint
GEThttps://airports-reference.x402tookit.com/airports-near?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover and rank airports by proximity to a geographic coordinate — ideal for travel planning, logistics, flight routing, or any use case where you have a lat/lon and need nearby airport options. Prefer this over a code-lookup endpoint when you don't already know the airport identifier. The size and scheduled-service filters make it especially useful for finding only commercially relevant airports.
Side effects
- Missing required lat or lon parameters returns a validation error
- lat outside -90 to 90 or lon outside -180 to 180 returns an error
- radiusKm outside 1–1000 range returns a validation error
- limit outside 1–25 range returns a validation error
- No airports found within the specified radius returns an empty airports array
- Invalid type filter value (not any/large/medium/small) may return an error or be ignored
- Payment failure (insufficient USDC balance or x402 auth issue) returns a 402 error
