## 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-airlines-lookup-58d1e9da
```

Example prompt: Can you search Aviationstack for airlines matching 'Delta' and return up to 5 results with their IATA codes and country?

## When to prefer this

Use this endpoint when you need to look up airline identity data such as IATA/ICAO codes, country of origin, or active status by airline name. Prefer this over flight-status endpoints when you only need carrier metadata, not real-time flight data.

## Known failure modes

- No airlines match the search query — returns empty results array
- Invalid or missing API credentials — returns 401 unauthorized error
- Limit parameter out of range — may return error or default result count
- Search string too vague returns too many or irrelevant results
- Gateway timeout if Aviationstack upstream is unavailable

## How this service works

Airline reference data.

## Output

A list of airline records matching the search query, each containing airline name, IATA code, ICAO code, country of origin, and active/inactive status, up to the specified limit.
