# Reference This section has articles with more technically oriented content. That is, each article explains some topic or concept in depth, getting "into the weeds". For example, there's an article on all the details of the [export file](/reference/data-export.md), and an article on [cost per use](/reference/cost-per-use-cpu.md). Please let us know if you have any feedback on these articles or have ideas for new articles at --- # 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://docs.unsub.org/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.
