## 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 x402helper-xyz-flight-search-b41d15aa
```

Example prompt: Can you search for available flights from New York to London departing this Friday?

## When to prefer this

Use this endpoint when you need to search for available flights and are operating in an x402 micropayment-enabled agent context. It is backed by stabletravel.dev and is suitable for AI agents that can autonomously pay $0.013 USDC per query. Prefer this over scraping or other travel APIs when you need a simple GET-based flight search with automatic micropayment handling.

## Known failure modes

- Missing required query parameters returns validation error
- No flights found for the given route or date returns empty results
- Payment failure or insufficient USDC balance blocks access
- Invalid airport codes or dates return error responses
- Rate limiting if too many requests are made in succession
