Hotel Inventory

Hotel inventory refers to the available room types, quantities, and corresponding prices that a hotel has open for booking on a given date or date range. It is the supply side of the hotel booking market.

Hotel inventory is highly dynamic - availability and pricing change continuously as rooms are booked or released, and as pricing algorithms respond to changes in occupancy and competitive rates. This makes hotel inventory APIs some of the most latency-sensitive data APIs.

APIs that query hotel inventory return real-time availability for a specified location, check-in date, check-out date, and occupancy. The response includes room types, prices per night, and rate conditions (refundable vs. non-refundable). This data is essential for building booking engines and price comparison tools.
