Accommodation API for hotel search and booking

Add hotel search, live rates, and booking to your site. Resolve a destination, list properties, validate the rate, and confirm, all from one REST API.

What it solves

Hotel inventory is large and rates move fast. This accommodation API gives you a public place search, availability in city and hotel modes, rate validation with a hold window, and a clear book-then-confirm flow, with prices in USD.

What you get

• Public place search wires straight into a type-ahead box.
• One availability endpoint lists a city or opens a single hotel.
• Validate the rate, hold the room, then confirm and charge.
