Faster Target Validation and Clearer Errors

This release introduces zero-cost short-circuiting when requests specify incompatible execution constraints, alongside faster connection pre-checks for unreachable target sites. Diagnostic error messaging across the platform has also been updated for actionable clarity, and organization billing reports now include complete historical usage.

Highlights
Zero-cost short-circuiting for constraint limits

When request parameters set execution limits below what a target domain requires, requests now short-circuit immediately. These requests return instant diagnostic feedback without incurring billing charges.

Faster validation for unreachable target servers

Lightweight pre-checks now verify target web server availability before full execution. Requests targeting unreachable origins fail significantly faster, avoiding unnecessary waiting times.

Bug Fixes

6

Accurate messaging for target DNS errors

Transient domain resolution failures on target URLs are no longer misclassified as security blocks. You now receive explicit error feedback whenever a target hostname fails to resolve.

Clearer diagnostic error and suggestion messages

Error messages and troubleshooting tips returned during access blocks have been updated for clarity. Diagnostic responses now offer actionable guidance instead of suggesting sites are unscrapable.

Restored page context in script evaluation

Custom JavaScript evaluation actions now execute in the main page window context as expected. Evaluated scripts maintain full access to DOM elements, window properties, and global objects.

Safe payment deposits during network dropouts

Quick-deposit account funding calls now include idempotency keys and enhanced retry safety. Network connection dropouts during deposit processing no longer report false failure statuses.

Historical analytics for organization accounts

Organization usage dashboards and breakdown charts now correctly include historical usage recorded before team setup. Account administrators can view complete usage trends across all billing periods.

Accurate organization refund attribution

Automatic refunds for add-on services now strictly attribute credits to the organization funding principal. Credits are reliably returned to the primary team wallet in multi-user accounts.

Plus 23 internal changes for stability and performance.
