## 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 lilambd-airport-search-8b1f23bb
```

Example prompt: Can you find me a list of international airports in France that have scheduled service? Show me up to 20 results.

## When to prefer this

Use this endpoint when you need to search or filter a structured airport database by name, city, country, type, or scheduled service. Prefer this over general web search when you need clean, structured airport records with consistent fields. Best for travel planning agents, itinerary builders, or aviation tools that need authoritative airport lookup without scraping.

## Known failure modes

- Empty result set (data: [], count: 0) when no airports match the query parameters
- Invalid country code returns no results or an error
- Out-of-range limit value may be clamped or rejected
- Missing required 'input' wrapper causes schema validation error
- Payment failure via x402 protocol returns 402 status and no data

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

Returns a JSON object containing a 'data' array of matching airport records, a 'count' of results found, and an 'attribution' string with source licensing information. Each record likely includes airport identifiers, names, location data, type, and scheduled service status.
