How this service works
Prüft am Objekt stylesheet den Befund Gesamtladezeit.
Output
Returns a performance finding (Befund) for the stylesheet object at the given URL, specifically the total load time (Gesamtladezeit) — how long the stylesheet takes to fully download from start to finish. Likely includes timing values and possibly a pass/fail or rating assessment.
Example use cases
CSS performance audit before launch
“We're about to launch our new site — can you check the total load time for the stylesheet at https://myshop.com/assets/theme.css and let me know if it's slow?”
Comparing stylesheet speed across environments
“I want to compare our stylesheet load time — check the total load time of https://staging.myapp.com/css/app.css and report back what you find.”
Monitoring third-party stylesheet delivery
“Can you measure how long it takes for the Google Fonts stylesheet at https://fonts.googleapis.com/css2?family=Roboto to fully load?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/gesamtzeit/stylesheetWhen to prefer
Use this endpoint when you specifically need to measure the total download/load time of a stylesheet (CSS) resource on a public web server. It is part of the Halowerk Tempo suite, which specializes in granular per-object web performance checks. Prefer this over generic page speed tools when you need isolated stylesheet timing rather than full-page performance metrics.
Side effects
- Target URL is not publicly accessible or returns a non-2xx response
- URL does not point to a stylesheet resource
- CSS selector matches no element or is malformed
- URL exceeds 2048 character limit
- Request times out if the target server is very slow
- Invalid user_agent pattern causes validation error
