Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.obscura.sh/quickstart/extract-data.md). # Extract data `--dump` formats the page output without writing JavaScript. ```bash obscura fetch https://example.com --dump html obscura fetch https://example.com --dump text obscura fetch https://example.com --dump markdown obscura fetch https://example.com --dump links obscura fetch https://example.com --dump assets obscura fetch https://example.com --dump original obscura fetch https://example.com --dump cookies ``` ### `html` Rendered HTML after JavaScript runs. Default. ```bash obscura fetch https://news.ycombinator.com --dump html > hn.html ``` ### `text` Plain text. No markup. ```bash obscura fetch https://en.wikipedia.org/wiki/Rust_(programming_language) --dump text ``` ### `markdown` Markdown conversion: headings, lists, links, code blocks, images. ```bash obscura fetch https://docs.example.com/page --dump markdown > page.md ``` ### `links` Every `` on the page, one per line. ```bash obscura fetch https://example.com --dump links ``` ### `assets` Every external resource (stylesheets, scripts, images, fonts, iframes), plus the URLs the page requested through `fetch()`/XHR, one JSON object per line. ```bash obscura fetch https://example.com --dump assets ``` ### `original` The raw HTML the server sent, before JavaScript ran. ```bash obscura fetch https://my-spa.example --dump original > before.html obscura fetch https://my-spa.example --dump html > after.html diff before.html after.html ``` ### `cookies` Every cookie in the jar as a JSON array, including HttpOnly cookies that `document.cookie` cannot see. Useful for capturing session tokens set by anti-bot challenges. ```bash obscura fetch https://example.com --dump cookies ``` ### With `--wait-until` `--dump` runs after the wait condition: ```bash obscura fetch https://my-spa.example --wait-until load --dump markdown ``` ### Pipe and redirect ```bash obscura fetch https://example.com --dump markdown > example.md obscura fetch https://example.com --dump text --quiet | wc -w ``` --- # 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.obscura.sh/quickstart/extract-data.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.
