## 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-dev-b587b3ba
```

Example prompt: I found a flight from JFK to LAX on May 20th for 2 adults in economy — I have the departure token from the search. Can you fetch all the booking options and price insights for it so I can see where to actually purchase the ticket?

## When to prefer this

Use this endpoint after obtaining a departure_token from a flight search result when you need to retrieve specific booking URLs and price insights for a chosen itinerary. This is the second step in a two-step flight booking workflow — search first, then call this endpoint with the token to get actionable booking links.

## Known failure modes

- Invalid or expired departure_token returns empty booking options or error
- Missing required parameters (departure_id, arrival_id, outbound_date) returns 400 validation error
- departure_token from a different search context may yield no results
- Round-trip type (type=1) without return_date may cause unexpected behavior
- Invalid currency code (not 3-char ISO) returns validation error
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Get booking options for a specific flight. Requires a departure_token from a search result.

## Output

Returns booking options including direct airline links and third-party booking URLs, price insights (price level, lowest price, typical price range, price history), and structured fare information for the selected flight itinerary
