> For the complete documentation index, see [llms.txt](https://docs.webscrapingapi.com/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.webscrapingapi.com/browser-api/advanced-api-features.md). # Advanced API Features The full power of the BrowserAPI stands in its ability to allow users to customise each request. From simply [rendering JavaScript files](/browser-api/advanced-api-features/rendering-javascript.md) on targeted websites, to creating [sessions](/browser-api/advanced-api-features/sessions.md), or even [parsing the HTML file in a JSON format](/browser-api/advanced-api-features/json-dom-response.md), almost everything is possible by adding the respective parameters to your request. This section documents the more advanced API features, offering you an overview of each parameter and also implementation examples in the most used programming languages. After reading through our full documentation, you should be able to spin a web scraping project in little to no time. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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, and the optional `goal` query parameter: ``` GET https://docs.webscrapingapi.com/browser-api/advanced-api-features.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
