How this service works
Prüft am Objekt dokument den Befund Zeit bis zum sichtbaren Renderstart.
Output
Returns a performance measurement indicating the elapsed time (in milliseconds or seconds) from request initiation until the document's first visible render event, along with any relevant metadata about the probe result.
Example use cases
Audit slow-loading document page
“Check the renderstart time for the document at https://mysite.com/whitepaper.html — I want to know how long it takes before anything becomes visible on screen.”
Monitor publishing platform document speed
“Measure the time-to-first-visible-render for the document at https://press.example.com/article — I'm auditing our editorial platform's performance.”
Compare document render speed before and after optimization
“Can you benchmark the renderstart time for https://docs.myapp.com/guide before I push my CSS changes, so I have a baseline to compare against?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/renderstart/dokumentWhen to prefer
Use this endpoint when you need to specifically measure the time-to-first-visible-render (Renderstart) for a document object (e.g. an HTML page, PDF, or published document). Prefer this over generic page-speed endpoints when your target is a document URL rather than a full webpage, video, image, or script, and you need a focused Renderstart metric rather than full-page load or TTFB metrics.
Side effects
- URL is not publicly accessible or returns a non-200 status — probe fails with an unreachable error
- Document is behind authentication or a firewall — connection refused or timeout
- CSS selector provided matches no element — defaults to first match or returns no-selector error
- URL exceeds maxLength of 2048 characters — validation error
- Malformed URL or unsupported protocol — input validation failure
- Rendering engine timeout if document is extremely slow to respond
