description	Scrape the web over the iii bus with Scrapling — fast HTTP fetch with TLS impersonation, a Camoufox anti-bot browser (Cloudflare bypass), full Playwright rendering, screenshots, and CSS/XPath/regex/adaptive extraction.

scrapling

The scrapling worker puts Scrapling on the iii bus. Three fetch tiers share one output shape: scrapling::fetch (fast HTTP, curl_cffi TLS impersonation), scrapling::stealthy-fetch (Camoufox stealth browser — solves Cloudflare/Turnstile, hardens WebRTC/canvas), and scrapling::dynamic-fetch (Playwright/Chromium — JS rendering, waits, XHR capture). Every fetch can extract in the same call by passing a selectors list, and can fan out over a urls array. Parsing is also exposed standalone (extract, css, xpath, regex, find-similar) for HTML you already have.

Fetches return {status, url, headers, cookies, encoding} plus extracted (when selectors given) and html (when include_html: true). A bulk call returns {results: [...]}.

When to Use

• Grab a page fast and pull fields in one shot: scrapling::fetch with url and selectors: [{name, css, all?}].
• Get past anti-bot / Cloudflare: scrapling::stealthy-fetch with solve_cloudflare: true.
• Render JS-heavy pages or wait on selectors: scrapling::dynamic-fetch with wait_selector, network_idle, or capture_xhr.
• Screenshot a page: scrapling::screenshot (fetcher: dynamic|stealthy, full_page?).
• Parse HTML you already fetched elsewhere: scrapling::extract / scrapling::css / scrapling::xpath / scrapling::regex.
• Scrape a repeating list from one example element: scrapling::find-similar with an anchor CSS selector.
• Fetch many URLs at once: pass urls: [...] to any fetch function.

Boundaries

• The fetch functions make outbound requests to arbitrary URLs and are not agent-callable without human approval (SSRF surface); the pure parsers are (see iii-permissions.yaml).
• The stealthy/dynamic fetchers and screenshot need the bundled browsers (Camoufox/Chromium) installed by scrapling install in the image.
• Non-JSON Scrapling options (Python page_action/page_setup callbacks, proxy rotators, session objects, the Spider crawl layer) are intentionally not exposed. Pass a single proxy string, not a rotator.
• Selector spec fields: {name, css|xpath|regex, attr?, html?, all?} — attr pulls an attribute, html pulls inner HTML, otherwise text; all returns a list.

Functions

• scrapling::fetch — HTTP get/post/put/delete; url|urls, method, headers, impersonate, selectors, include_html.
• scrapling::stealthy-fetch — Camoufox anti-bot fetch; solve_cloudflare, block_webrtc, wait_selector, selectors, bulk.
• scrapling::dynamic-fetch — Playwright fetch; network_idle, wait_selector, real_chrome, cdp_url, capture_xhr, selectors, bulk.
• scrapling::screenshot — page as image content blocks; fetcher, full_page, format.
• scrapling::extract — parse html with a selectors list → named map.
• scrapling::css — one CSS query over html; first?, attr?.
• scrapling::xpath — one XPath query over html; first?, attr?.
• scrapling::regex — regex over the visible text of html; first?.
• scrapling::find-similar — anchor element + structurally similar elements.
