## 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`):

## When to prefer this

Choose this endpoint when you need Google Travel Explore's flight price discovery data in structured JSON without managing a Google API key or subscription. Ideal for AI agents performing travel planning, fare comparison, or flexible-date searches where pay-per-call pricing ($0.05 USDC) is preferable to a monthly SaaS subscription. Best for one-off or low-volume queries where cost predictability matters.

## Known failure modes

- Invalid or unsupported airport codes return an error or empty results
- Dates in the past or incorrectly formatted dates (non-YYYY-MM-DD) may cause errors
- Missing required parameters (departure_id or arrival_id) will return a validation error
- Return date missing for round trip (type=1) requests will fail
- Unsupported country/language code combinations may yield unexpected results
- Payment failure (insufficient USDC) will block the request at the x402 layer
