Scrapingbypass API cannot be directly integrated into Tampermonkey (UserScript) environments.
Why Direct Integration is Not Supported
Tampermonkey scripts execute within the context of your local browser. Our service operates as a backend-to-backend proxy solution that requires control over the network layer to perform the following:
- TLS/JA3 Impersonation: Modifying the low-level handshake protocols that browsers do not expose to JavaScript.
- WAF Bypass Logic: Executing JS challenges and Turnstile solutions within our secure, sandboxed environment.
- Proxy Authentication: Managing
user-passcredentials at the request level.
Since Tampermonkey relies on the host browser's native fetch() or XMLHttpRequest APIs, it is subject to the browser's fixed fingerprints and CORS (Cross-Origin Resource Sharing) restrictions. These limitations prevent the script from masquerading as a different browser or bypassing Cloudflare's deep packet inspection.
Recommended Architecture
To use Scrapingbypass API in conjunction with automated workflows, you must move the request logic to a backend environment.
| Feature | Tampermonkey (Client-side) | Scrapingbypass API (Server-side) |
|---|---|---|
| Network Control | High-level (limited by browser) | Low-level (Full TLS/HTTP2 control) |
| Fingerprint Customization | Not possible | Full JA3/UA impersonation |
| WAF/Challenge Solving | Triggers browser detection | Managed automatically via V2 API |
| Authentication | Browser-managed | Server-side proxy credentials |
Alternative Workflow
If you need to automate data collection from a browser-like environment, integrate Scrapingbypass API using one of the following methods:
- Direct API Requests: Use
Python (Requests/Aiohttp),Node.js (Axios), orGoto call our endpoints. - Headless Browsers: Configure Scrapingbypass Proxy within
Puppeteer,Playwright, orSelenium. - Automation Engines: Integrate with tools like OpenClaw to manage large-scale data extraction.
