Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-book-94b2e2ef -d '<json body>'
```

Example prompt: Book the ground transfer using offer ID 'abc123XYZ', passenger name John Smith, and charge it to the payment on file — also include flight number BA456 so the driver knows when to pick him up.

## When to prefer this

Use this endpoint after searching for transfer offers via the StableTravel Transfer Search endpoint and selecting a specific offer. This is the confirmation/purchase step — it should only be called once you have a valid offerId from a prior search. Prefer this over generic travel booking APIs when you need Amadeus-powered ground transfer confirmation with structured passenger and payment data.

## Known failure modes

- Invalid or expired offer ID returns an error — offers have a time-limited validity window
- Missing required passenger or payment fields returns a validation error
- Payment failure returns a transaction declined error
- Offer no longer available at time of booking returns availability error
- Malformed passenger data returns schema validation error
