# 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.chatalog.ai/zh-cn/settings/shuang-zhong-ren-zheng-2fa/shi-yong-2fa-zai-wang-ye-ban-deng-ru.md?ask=
```
The question should be specific, self-contained, and written in natural language.
