## 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 whatchuneed-flight-utility-dff19fab -d '<json body>'
```

Example prompt: Find me available flights from New York JFK to London Heathrow next Friday, preferably direct or with at most one stop.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call flight search without managing a full travel API integration. It accepts free-text natural language input, making it easy to use in agent pipelines without rigid parameter schemas. Best for prototyping or lightweight agent workflows that occasionally need flight data.

## Known failure modes

- Vague or ambiguous input string may return no results or irrelevant data
- Missing origin or destination in the input string causes lookup failure
- Invalid or past dates may result in empty results
- Service may time out for complex multi-leg itinerary queries
- Unsupported routes or very thin markets may return no options
