Handle Cloudflare challenges at the protocol and session layer
Move Cloudflare JS Challenge, Turnstile, cf_clearance and WAF fingerprint handling into the access layer instead of rebuilding your crawler. Send documented request settings, maintain consistent sessions and validate the returned content before parsing.
Session-aware bypass:
Extracts and maintains cf_clearance with matching User-Agent, proxy IP, and TLS JA3/JA4 fingerprint so follow-up requests stay aligned.
Ready-to-parse output:
Return full page HTML or upstream JSON through one API key, reducing local browser overhead and parser interruptions.
Automated Cloudflare Turnstile handling
Built for modern Turnstile and silent challenge flows. Submit sitekey, action, cData, headers, and context parameters, then let the cloud runtime complete verification and return a token or validated response.
Precise x-cb-sitekey routing
Provide the target Sitekey and Scrapingbypass builds the challenge environment needed for automated verification.
Verified token response
Receive a usable token or validated page response for form submission, scraping jobs, and agent workflows.
Action and CData support
Pass advanced widget parameters to match how each protected site validates Turnstile requests.
Invisible challenge support
Handle silent Cloudflare checks without local mouse simulation or fragile browser scripts.
cf_clearance and sticky session management
Cloudflare clearance cookies are often bound to IP, browser fingerprint, and request timing. Scrapingbypass manages that relationship so long-running scrapers can continue after the initial challenge is solved.
Automatic cookie handling
Parses Set-Cookie headers and preserves post-challenge clearance credentials for later requests.
Cookie and fingerprint binding
Keeps cf_clearance aligned with TLS fingerprints, proxy IP, and User-Agent to avoid environment mismatch resets.
Login cookie passthrough
Forward existing business cookies so authenticated scraping and WAF bypass can run in one request pipeline.
Clearance renewal logic
Detects expired or invalid sessions and refreshes the bypass flow before data collection stalls.
TLS fingerprint and HTTP/2 behavior matching
Anti-bot systems now evaluate TLS, HTTP/2, header order, and browser-like behavior together. Scrapingbypass helps your scraper send traffic that stays consistent with real browser sessions.
JA3/JA4 browser profiles
Select TLS handshake profiles that better match modern Chrome-like traffic.
HTTP/2 request consistency
Aligns stream behavior and protocol traits to avoid obvious automation signatures.
Cloud-side JS challenge execution
Process complex JavaScript verification remotely instead of running heavy local browsers.
Handshake compatibility
Matches supported cipher suites and protocol settings to reduce SSL resets and failed fetches.
Verified HTML, JSON passthrough, and global routing
Choose the response format and network route that fit each scraping task. Scrapingbypass combines verified content output with residential and datacenter routing for geo-sensitive and WAF-protected targets.
Full page source retrieval
Return verified HTML instead of intermediate challenge pages, ready for extraction.
JSON passthrough support
Preserve upstream API responses when the protected endpoint returns structured data.
Residential IP routing
Use high-trust broadband routes when datacenter ranges face stricter blocking.
Header-based authentication
Manage high-concurrency jobs with simple x-cb-apikey authentication and unified quota control.

FAQHardcore Engineer Version
How do I use x-cb-sitekey to pass Turnstile verification?
Send a request including the target site's sitekey. Scrapingbypass runs verification in the cloud and injects the token into the request or returns it directly.
Does the API return verified HTML or the original 403/challenge page?
It returns the final HTML after the Cloudflare challenge is passed. The 5-second shield stage is handled automatically.
Can I reuse the cf_clearance in my own environment?
Yes - as long as your User-Agent and TLS fingerprint (JA3) remain consistent. Best practice: keep everything within the Scrapingbypass session.
Why does my Python script get blocked due to TLS fingerprinting?
Default HTTP libraries don't match real browser TLS traits. Scrapingbypass simulates JA3/JA4 to mask your traffic as Chrome at the protocol layer.
Can Scrapingbypass handle Cloudflare verification inside POST requests?
Yes. It detects protection strategies dynamically and fills required verification parameters so POST bodies reach the origin correctly.
Can the response include the origin site's raw JSON format?
Yes. With response configuration enabled, you can fetch the origin JSON payload directly while preserving upstream headers.
Reviews from Our Users
"I used to write hundreds of lines just to extract cf_clearance. Now it's literally one parameter - and the TLS simulation is insanely accurate."
"The best part is getting verified HTML directly. No more messing with heavy Puppeteer setups - concurrency improved 5x."
"w-cb-sitekey support is rock solid, especially for silent Turnstile. It's basically near-100% pass rate."
"Not just cookies - even H2 weighting is emulated. That's a killer feature for high-intensity CF targets. The docs are super clear."
"For data integration, getting the post-challenge JSON response directly saves a ton of work - no need to analyze encrypted routes."
"Auto fingerprint matching by domain + cf_clearance renewal makes integration cost the lowest I've seen in the industry."
