  title: Booking.com Car Rentals Accommodations Constants API
  description: The Booking.com Car Rentals API is part of the Demand API and provides endpoints specific to the car rental segment of the connected trip experience. Developers can use it to search for available car rentals, retrieve car details, look up depots and suppliers, and access depot review scores. The API enables affiliate partners to integrate Booking.com's car rental inventory into their own platforms, offering users the ability to find and book vehicles as part of their travel planning workflow.
