Find the airports nearest to a caller-provided latitude/longitude, sorted by great-circle (haversine) distance with distance_km on each result. Searches 85,555 airports (OurAirports, public domain). Provide latitude and longitude (decimal degrees); optional radius_km, max_results (1-50, default 10) and type filter (e.g. large_airport only). Coordinates are INPUT only — nothing is stored or logged. Behavior: deterministic distance sort; confidence reflects proximity and airport size (a large airport within 25 km scores high; closed/heliport/seaplane results cap lower). This tool does NOT geocode place names and does NOT compute routes — pass coordinates you already hold. Rate-limited (anonymous use: 25 requests/day per IP): a 429 error body carries retry_after_seconds and a Retry-After header — back off and retry, or call get_subscribe_link for higher limits. Returns: count and results[] (the airport record plus distance_km) under result, plus confidence, _source and citation (the FreightUtils v1 response envelope). Limitations: reference data only — not for navigation; verify codes with IATA / ICAO. Related: airport_lookup (exact code or name lookup, no distance), unlocode_lookup (named transport-location search).
