# Enhanced Shopping (EST) – Detailed Rate Information ### Overview The Enhanced Shopping Transaction (EST) API provides detailed room and rate information for multiple properties, supporting up to 200 properties in a single transaction. The returned data includes: * Room and rate descriptions * Pricing information * Policies and Restrictions In addition to these core features, the EST API supports advanced functionalities such as: * Negotiated rate processing * User-specified timeouts * Multipart responses * Support for multiple languages While these advanced features enhance the flexibility and functionality of the API, they are not mandatory for a basic implementation. Details about each feature are outlined in the sections below: #### Simple Example The following is a simple request for 1 adult and 2 children staying between 1-4 September. The example just contains two properties, although up to 200 are supported. **Note:** The **VersionCompliance (=**Enhanced\_V1**)** attribute must always be sent to indicate that this is the ‘enhanced shopping’ request ```xml ``` The response message shown below includes the available rooms and rates for the two requested properties. As the amount of information returned will vary by property, the first property (UI;12345) is an example of fairly comprehensive information, while the second property (UI;61829) is less detailed. ```xml ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
