Extract data from web pages using the scrapling Python library — select the appropriate fetcher tier (HTTP, stealth Chromium, or full browser automation) based on target site defenses, configure headless browsing, and extract structured data with CSS selectors. Use when WebFetch is insufficient for JS-rendered pages, anti-bot-protected sites, or structured multi-element extraction requiring DOM traversal.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Headless Web Scraping Extract data from web pages that resist simple HTTP requests — JS-rendered content, Cloudflare-protected sites, and dynamic SPAs — using scrapling's three-tier fetcher architecture and CSS-based data extraction. ## When to Use - Target page requires JavaScript rendering (SPA, React, Vue) - Site has anti-bot protections (Cloudflare Turnstile, TLS fingerprinting) - You need structured extraction of multiple elements via CSS selectors - Simple `WebFetch` or `requests.get()` returns empty or blocked responses - Extracting tabular data, link lists, or repeated DOM structures at scale ## Inputs - **Required**: Target URL or list of URLs to scrape - **Required**: Data to extract (CSS selectors, field names, or description of target elements) - **Optional**: Fetcher tier override (default: auto-select based on site behavior) - **Optional**: Output format (default: JSON; alternatives: CSV, Python dict) - **Optional**: Rate limit delay in seconds (default: 1) ## Procedure ### Step 1: Select Fetcher Tier Determine which scrapling fetcher matches the target site's defenses. ```python # Decision matrix: …

How to install
mdr add pjt222/agent-almanac/headless-web-scraping@sha256:1aba33de65350e75The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
