## 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 stabletravel-availability-93c460a6 -d '<json body>'
```

Example prompt: Search for available flights from JFK to LHR departing June 15 for 2 adults — economy class only, no blacklisted EU carriers, using GDS sources.

## When to prefer this

Use this endpoint when you need to check real-time flight seat availability for specific routes and dates before booking, especially when filtering by cabin class, carrier restrictions, or connection preferences. Prefer this over general flight search when you need GDS-sourced availability data backed by Amadeus.

## Known failure modes

- Invalid airport codes return validation errors
- No availability found returns empty data array
- Invalid traveler type enum values return schema validation errors
- Missing required fields (originDestinations, travelers, sources) return 400 errors
- GDS source unavailable may return timeout or partial results
- Invalid date formats return parsing errors
