How this service works
Prüft am Objekt skript den Befund Zahl renderblockierender Ressourcen.
Output
Returns a numeric finding (Befund) representing the count of render-blocking script resources detected on the target page or specified script element, along with audit metadata such as the target URL and selector used.
Example use cases
Pre-launch performance audit
“Before we go live with our new landing page at https://mysite.com/landing, can you check how many render-blocking scripts are on that page? I want to know if we need to defer or async any JS before launch.”
CI/CD performance regression check
“Run a render-blocking script check on https://staging.acme.com so I can see if our latest deploy introduced any new render-blocking JavaScript compared to before.”
Competitor page speed benchmarking
“Check how many render-blocking scripts are on https://competitorsite.com — I want to see how their JS setup compares to ours in terms of render-blocking resources.”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/blockierer/skriptWhen to prefer
Choose this endpoint when you need a precise, automated count of render-blocking script resources on a specific URL or page element, particularly for web performance auditing, CI/CD pipeline checks, or monitoring page speed regressions. It is purpose-built for the render-blocking-scripts metric specifically (as opposed to broader Lighthouse-style full audits), making it ideal for targeted, lightweight script-blocking checks at $0.001 per call.
Side effects
- Invalid or unreachable URL returns an error
- Non-public or localhost URLs are rejected
- CSS selector matches no element or multiple elements (first match used)
- Target page blocks crawling or returns non-200 status
- Malformed input schema causes validation error
- Request timeout if target page is very slow to respond
