How this service works
Prüft am Objekt iframe den Befund Zahl renderblockierender Ressourcen.
Output
Returns the number of render-blocking resources (scripts, stylesheets, etc.) found within the specified iframe object at the given URL, giving developers a concrete metric to guide optimization efforts.
Example use cases
Auditing a third-party widget iframe
“I've embedded a third-party chat widget in an iframe on my homepage at https://mysite.com — can you check how many render-blocking resources that iframe is loading so I can figure out if it's slowing things down?”
Monitoring ad iframe performance
“We're running an ad unit embedded as an iframe at https://publisher.com/ad-slot — please check the iframe matched by '#ad-frame' and tell me how many render-blocking resources it has right now.”
Pre-launch performance regression check
“Before we go live, can you audit the iframe at https://staging.myapp.com/checkout-widget — select it with the CSS selector '.checkout-iframe' and tell me the number of render-blocking resources it's triggering?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/blockierer/iframeWhen to prefer
Use this endpoint when you specifically need to measure render-blocking resources scoped to an iframe element rather than a full page or other resource type. It is ideal for isolating third-party embeds, ad slots, or widget iframes that may independently introduce performance bottlenecks without affecting whole-page metrics. Choose sibling endpoints for full-page, video, or API response analyses.
Side effects
- Invalid or non-public URL returns an error or empty result
- CSS selector matches no element or multiple elements — first match is used or error returned
- Target URL is unreachable or returns non-200 HTTP status
- iframe contains no detectable resources (count returns 0 but may indicate access restrictions)
- Malformed input schema (missing required 'ziel' field) causes request rejection
