Tempo Halowerk – Video Render-Blocking Resources Check

Use this endpoint when you specifically need to audit a video resource for render-blocking resource count as part of a web performance workflow. It is distinct from sibling endpoints that check other objects (pages, scripts, images, iframes) or other metrics (TTFB, visual render start, modern image formats). Choose this when the asset under test is a video and render-blocking resources are the metric of interest.

• URL is not publicly accessible — returns an error or empty result
• Non-video URL passed — audit may return unexpected or empty findings
• CSS selector matches zero elements — falls back to first matched element or returns no result
• Network timeout when fetching the target URL — request fails
• Invalid URL format — input validation error returned
