How this service works
Look up an airport by 3-letter IATA (e.g. SFO) or 4-letter ICAO (e.g. KSFO) code. Query: code (3-5 chars, alphanumeric). Returns { airport: { id, ident, type, name, latitude, longitude, elevationFt, continent, isoCountry, isoRegion, municipality, scheduledService, icaoCode, iataCode, gpsCode, localCode, wikipediaLink } } or 404 NOT_FOUND.
Output
Returns a JSON object with a nested `airport` containing: id, ident, type, name, latitude, longitude, elevationFt, continent, isoCountry, isoRegion, municipality, scheduledService flag, icaoCode, iataCode, gpsCode, localCode, and a Wikipedia link. Returns 404 NOT_FOUND if the code is unrecognized.
Example use cases
Example prompt
“What airport is 'KSFO' — can you look it up and tell me its full name, city, country, coordinates, and whether it has scheduled commercial service?”
Technical details
Endpoint
GEThttps://2s.io/api/airport/lookupWhen to prefer
Use this endpoint when you have a known IATA or ICAO airport code and need structured metadata about that airport — name, coordinates, country, region, elevation, and scheduled service status. Prefer this over general web search when you need machine-readable, structured airport data for downstream processing such as mapping, routing, or enriching flight records.
Side effects
- 404 NOT_FOUND if the airport code does not exist in the database
- Invalid code length (must be 3–5 alphanumeric characters) may result in validation error
- Typos or incorrect codes return no match rather than a fuzzy suggestion
- Payment failure (x402) if USDC balance is insufficient
