## 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 x402engine-hotel-search-via-google-hotels-f3621498
```

Example prompt: Search for hotels in Paris for 2 adults checking in April 15 and checking out April 18 — sort by highest rating and only show options under $400 per night in USD.

## When to prefer this

Use this endpoint when an agent needs real-time hotel availability and pricing for a specific location and date range, particularly when Google Hotels coverage is desired. Prefer this over generic web search when structured hotel data (prices, ratings, amenities, star class) is required. At $0.02 USDC per call via x402 micropayment, it is cost-effective for per-query hotel discovery in travel planning agents.

## Known failure modes

- Missing required parameters (q, checkInDate, checkOutDate) returns a validation error
- Invalid date format (not YYYY-MM-DD) causes a parse error
- No hotels found for the given query or date range returns an empty results set
- Invalid currency code returns an error or defaults to USD
- SerpApi upstream outage causes a 503 or timeout
- Invalid hotelClass value (outside 2-5) may return unexpected results
