Enhanced Extraction Speed and Success Rates

This update ensures that strict SSL configurations are consistently honored during request fallbacks. Developers can now trust that their secure connection policies remain in effect throughout the entire request lifecycle.

Highlights
Detection resistance major upgrade

Upgraded our browser engine to significantly improve request success rates on heavily secured websites. This update refines TLS handshakes and JavaScript behavior to bypass advanced detection systems.

Faster request start times

Optimized startup sequences reduce request initialization latency by up to 10 seconds for various domains. This results in significantly faster scrape times and improved API throughput.

Improvements

5

Faster request start times

Optimized startup sequences reduce request initialization latency by up to 10 seconds for various domains. This results in significantly faster scrape times and improved API throughput.

Extended timeout for synchronous extraction

Raised the default synchronous polling timeout from 60 to 90 seconds. This prevents premature timeouts on complex extraction tasks, ensuring long-running pages have ample time to parse.

Honeypot element stripping

Automatically strips hidden decoy and honeypot elements from target HTML pages before returning responses. This prevents downstream data extraction scripts from processing invalid or hidden decoy data.

Playground visual alignment

Adjusted the container height in the developer playground to match the configuration panel. This resolves a visual layout mismatch and offers a cleaner, more consistent testing interface.

General bug fixes and improvements

Plus 52 internal improvements for better reliability and performance.

Bug Fixes

4

Accurate empty schema filtering

Fixed an issue where extraction filters returning no matches would fallback to returning the entire unfiltered page structure. The API now correctly returns an empty JSON object as expected.

Fallback for LLM extraction

Resolved an issue where data extraction requests failed if a custom LLM API key was not configured. The platform now automatically falls back to system-provided keys to process requests.

Paced scheduling for concurrent requests

Fixed a bug where domain concurrency limits did not properly enforce delays, leading to premature retries. The request scheduler now strictly respects deferral windows for improved success.

Consistent Strict SSL Verification

Strict SSL verification settings are now reliably enforced during retry connection paths. This ensures your custom security policies remain active throughout the entire request lifecycle.

Security

2

Robust DNS rebinding protection

Implemented synchronous DNS resolution checks to eliminate security vulnerabilities from DNS rebinding during target validation. This hardens request routing safety for all API integrations.

JavaScript execution sandbox hardening

Enforced a strict evaluation allowlist gate for internal JavaScript environments. This strengthens server-side sandboxing and prevents potential remote code execution and injection vectors.

Plus 58 internal changes for stability and performance.
