## When to prefer this

Choose this endpoint when you need to retrieve Booking.com hotel and accommodation search results in structured JSON without managing a Booking.com API account or subscription. It is ideal for AI agents that need to compare hotels by price, rating, location, or star class for specific travel dates, guest counts, and budget constraints — especially when the per-call micropayment model fits better than a recurring API subscription.

## Known failure modes

- Invalid or unrecognized destination query returns empty results
- Invalid date format causes request failure
- children_ages not set when children count is specified may cause error
- max_price used without currency code causes invalid request
- Number of rooms exceeds number of adults causes validation error
- Unavailable dates or sold-out inventory returns empty listings
- Unsupported language code returns error or defaults to English
