How this service works
Airport lookup in a bundled OurAirports extract (public domain, dated in the answer): by IATA or ICAO code, by name or city words, or the nearest airports within a radius (up to 300 km) of a point. Covers large and medium airports and every airport with an IATA code; small airports without one are left out. Name, codes, type, city, country, coordinates, elevation and Wikipedia link. No time zone (not in the source).
Output
Returns a JSON object with a count, the original query echoed back, a source attribution, and an array of matching airports each containing IATA code, ICAO code, name, city, country, latitude, longitude, elevation in meters, airport type (large/medium/small), Wikipedia URL, and the data date and check timestamp.
Example use cases
Nearest airport to GPS coordinates
“Find the nearest airports within 150 km of latitude 48.8566 and longitude 2.3522 and list up to 5 results.”
Airport lookup by city name
“Search for airports in the city of Frankfurt and return all results with their IATA and ICAO codes.”
Validate IATA code for booking system
“I need to confirm that 'JFK' is a valid IATA code — can you look it up and give me the full airport name and country?”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/airports?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured airport data (codes, coordinates, elevation, type) and can identify airports by IATA/ICAO code, name/city text, or geographic proximity. Prefer over general web search when you need machine-readable, consistently structured airport records from a known public-domain dataset. Ideal for travel planning agents, flight booking assistants, and logistics tools needing fast, pay-per-call airport lookups without a subscription.
Side effects
- No airports found for the given code/query/coordinates — returns empty airports array
- Invalid IATA/ICAO code format — may return no results
- Coordinates outside valid range — may return no results
- Search radius out of allowed range (1–300 km) — likely validation error
- Limit parameter out of range (1–20) — may be clamped or rejected
- Payment failure if x402 micropayment not completed — 402 response
