## 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 airport-lookup-by-icao-code-a2ffe2d1 -d '<json body>'
```

Example prompt: What airport is EGLL? I need its full name, IATA code, country, region, and exact coordinates.

## When to prefer this

Use this endpoint when you have a 4-letter ICAO code and need structured airport metadata including geographic coordinates and IATA mapping. Prefer over manual lookups or general web searches when you need machine-readable, structured data for aviation workflows, route planning, or data enrichment pipelines.

## Known failure modes

- Invalid or unknown ICAO code returns an error or empty result
- Malformed ICAO (not 4 letters) may cause a validation error
- Network or upstream hexdb.io downtime could cause failures
- Payment failure (x402) if USDC not available or payment not authorized

## How this service works

Look up an airport by its 4-letter ICAO code and get the airport name, IATA code, country, region, and latitude/longitude. Free hexdb.io airport database, no key. Pass an ICAO like EGLL.

## Output

Returns a JSON object with the airport's full name, IATA code (3-letter), country, region, and geographic coordinates (latitude and longitude), sourced from the hexdb.io free airport database.
