## 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 the-stall-city-lookup-14a6532f
```

Example prompt: Look up cities matching 'London' in the United Kingdom and return up to 5 results — I need the city names and airport codes.

## When to prefer this

Use this endpoint when you need to resolve a city name, airport name, or IATA/ICAO code to structured location records — especially when building travel itineraries, flight search tools, or geolocation features. Prefer this over general geocoding APIs when airport code resolution is also needed. Ideal for no-account, pay-per-call workflows via x402/USDC.

## Known failure modes

- No results found for unrecognized keyword or code
- Invalid or misspelled country name returns empty or unfiltered results
- Exceeding max=20 causes validation error
- Missing required keyword parameter returns 400 error
- Payment failure (402) if USDC balance insufficient on Base mainnet

## How this service works

Search airports and cities by keyword, IATA code, or city name. Returns IATA/ICAO codes, coordinates, country, and timezone for each match — useful for travel planning, routing, and geographic enrichment.

## Output

Returns a list of up to 20 city or airport records matching the keyword, including city names, IATA/ICAO codes, country information, and related location metadata. Results are filtered by country if provided.
