## 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 aviationstack-cities-ce67d7e2
```

Example prompt: Can you look up city details for Paris in the AviationStack cities database so I can get the IATA city code and country info for flight planning?

## When to prefer this

Use this endpoint when you need to resolve a human-readable city name to an aviation city code or get structured city metadata for use in flight search, airport lookup, or route planning. Prefer this over the Airports endpoint when the user is searching at the city level rather than for a specific airport.

## Known failure modes

- No results found for obscure or misspelled city names
- Ambiguous city names returning multiple results requiring disambiguation
- Empty response for cities without aviation infrastructure
- Rate limiting or authentication errors if API key is invalid or quota exceeded
- Truncated response for very common city names with many matches
