# External API Reference The following pages will show you alternative ways of communicating with our API such as HTTP, TCP, and UDP. These methods are useful primarily when you are not calling the API from a data controller. If you are building a JavaScript-based data controller, we recommend you stick to the [Controller API](/captivate-api/javascript-api-reference.md). --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developers.newbluefx.com/captivate-api/advanced-api-reference.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
