How this service works
Bypasses Cloudflare anti-bot via Scrapling, extracts clean DOM to LLM Markdown, and runs CanaryGuard deterministic sanitization.
Output
Returns sanitized web page content converted to clean LLM-readable Markdown, with prompt-injection attempts and wallet-drainer patterns scrubbed by CanaryGuard deterministic sanitization, ready for safe ingestion into an agent context window.
Example use cases
Scraping Cloudflare-gated competitor pages
“Can you pull the content from https://competitor.com/pricing — it blocks normal scrapers — and give me a sanitized markdown version I can safely read without worrying about prompt injections?”
LLM-safe news article extraction
“Fetch this paywalled or bot-protected article at https://news-site.com/article/12345 using a GET request and convert it to clean markdown, making sure any malicious content is scrubbed before you put it in my context.”
Agent research on protected data portal
“I need you to hit https://data-portal.com/api/search with a POST request and body {"query":"AI regulations 2024"}, then return the page content as sanitized LLM markdown — the site blocks normal bots so use stealth mode.”
Technical details
Endpoint
POSThttps://stealthguard-402.onrender.com/v1/stealth_scrape_and_sanitize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch content from a URL that actively blocks scrapers or bots (e.g. Cloudflare-protected sites) AND you need the output to be safe for direct injection into an LLM context window. It combines anti-bot bypass with sanitization in a single call, making it ideal for autonomous agents that cannot risk prompt-injection attacks from untrusted web content. Prefer alternatives for simple, unprotected URLs where raw HTTP fetch suffices.
Side effects
- Target site may have advanced bot detection beyond Cloudflare that still blocks the request
- Malformed or unreachable target URL returns an error with no content
- Sites requiring JavaScript-heavy rendering beyond DOM extraction may return incomplete content
- CanaryGuard may over-sanitize legitimate content that pattern-matches injection signatures
- Rate limits or network timeouts on the render.com host may cause slow or failed responses
