Ad Slot Verification — Frequently Asked Questions

One completed page load for a target URL in a selected check context (GEO + device), with verification of up to 5 predefined ad slots. Each verified page produces statuses, screenshots, JSON metadata, and a UTC timestamp.

Each verified page checks up to 5 predefined selectors. If you need to verify more slots, you can run multiple checks with different selector sets for the same URL.

These are valid verification outcomes, not errors. CHALLENGE_DETECTED means an anti-bot challenge or interstitial was encountered. BLOCKED means access was prevented in that environment. Both are billable because the page load was completed and evidence was captured.
