## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability opendata402-airport-lookup-0fc4a2ce
```

Example prompt: What are the full details for Amsterdam Airport Schiphol — its IATA and ICAO codes, coordinates, elevation, country, and whether it has scheduled service?

## When to prefer this

Choose this endpoint when you need structured, authoritative airport reference data — especially coordinates, codes, type, and scheduled-service status — for travel itinerary planning, logistics routing, or aviation lookups. It covers ~9,000 large, medium, and IATA-coded airports globally with nightly-refreshed OurAirports data. Prefer it over general geocoding APIs when the entity is specifically an airport and you need both IATA and ICAO identifiers together.

## Known failure modes

- No results found if the IATA/ICAO code is invalid or not in the database
- Ambiguous name/city queries may return multiple results requiring further filtering
- Small or private airports not assigned IATA codes may not appear
- Stale data possible for recently opened or closed airports despite nightly refresh
- Missing q or code parameter returns an error requiring at least one search term

## How this service works

Airport lookup by IATA code (AMS), ICAO code (EHAM) or name/city: name, type, city, country, region, coordinates, elevation, scheduled service and both codes, for about 9,000 large, medium and IATA-coded airports worldwide. Use it for travel, logistics and aviation tasks. OurAirports data, public domain, refreshed nightly.

## Output

Returns a JSON object (or array) with airport name, type (large/medium/small), city, country, region, geographic coordinates (latitude/longitude), elevation in feet, scheduled service flag, IATA code, and ICAO code for each matched airport.
