UltraDirect is also connected to the RateGain Hotel Content Database, which provides detailed property information and images. UltraDirect supports: • Fast, immediate confirmation of booking and cancellation requests • Easily make changes to reservations without a cancellation or rebooking • Secure access to negotiated rates • Flexible and customizable XML transaction interface which allows complete control of the process flow and how the information is presented to end users. • Powerful property search capabilities, including by keyword, address or airport code • Access to weekly and monthly transaction reports --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://developer.rategain.com/ultradirect.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
