Why Scrapingbypass
Diagnose 403, 503, timeout and proxy errors from one troubleshooting path
Diagnose failed requests before spending time on retries. This center covers Cloudflare challenge failures, 403 responses, timeouts, proxy errors, region mismatches, balance and queue limits. The DataDome troubleshooting checklist helps identify failed verification, CAPTCHA loops and session mismatches so your application can return an actionable diagnostic instead of empty data.
Use logs to reduce blind retries
Scrapingbypass returns status codes, response messages, screenshots and structured logs so teams can decide whether to retry, change region, use browser mode or adjust concurrency.
Why Scrapingbypass
Diagnose 403, 503, timeout and proxy errors from one troubleshooting path
This error code center helps developers and operations teams understand failed scraping API requests, including 403 forbidden, Cloudflare challenge failures, timeout responses, proxy errors, region mismatch, insufficient balance and overloaded task queues.

Use cases
Representative business scenarios
From one-off validation to long-running monitoring, combine capabilities by page complexity and output requirements.
Existing crawler integration
Keep current collection logic and move access stability into the Scrapingbypass layer.
Browser automation
Add proxy, session, screenshot, and retry capabilities to Playwright, Selenium, and Puppeteer.
Geo access verification
Validate pages, ads, search results, and redirects by country and language.
Long-term monitoring
Track availability with logs, screenshots, status codes, and retry rules.
Budget estimation
Estimate launch cost by requests, traffic, screenshots, rendering, and retries.
Integration steps
Connect the Scrapingbypass access layer in 4 steps
Validate one high-value page first, then expand into scheduled workflows, batch collection, or monitoring systems.
01. Define target access
Confirm URLs, regions, frequency, output format, and workflow scope.
02. Choose access strategy
Pick API, rendering, screenshots, dynamic IPs, sticky sessions, and retry rules.
03. Connect business systems
Send results to crawlers, AI agents, workflows, QA, or internal monitoring.
04. Review logs and optimize
Use status codes, failure reasons, screenshots, and logs to improve stability.
FAQ
Frequently asked questions
How is it different from a normal proxy?
A normal proxy mainly provides an exit. Scrapingbypass also covers challenge handling, geo context, dynamic pages, screenshots, structured output, retries, and logs.
Can existing crawlers use it?
Yes. Existing crawlers can connect through Proxy mode, while complex pages can be handled through API mode.
Does it support geo exits?
Yes. Tasks can be organized by country, language, device, and exit region for SEO, ads verification, and geo monitoring.
Why does DataDome verification fail or return 403?
A DataDome 403 response can represent a verification step, a session mismatch or an access-policy block. Inspect the body, content type, cookies and approved proxy context before retrying. Use the troubleshooting workflow to return a clear diagnostic, and stop when access is denied. See the DataDome workflow.
