How this service works
Prüft am Objekt dokument den Befund Zeit bis zum ersten Byte.
Output
Returns a performance finding object containing the measured Time to First Byte (TTFB) for the specified document URL, indicating how quickly the server begins sending a response after a request is made.
Example use cases
Diagnose slow server for a landing page
“My landing page at https://www.mystore.com/sale feels sluggish — can you measure the TTFB so I know if the server response itself is the bottleneck?”
Monitor TTFB for an API documentation page
“Check the time to first byte for https://docs.myapi.com/reference and let me know if the server is responding quickly enough.”
Benchmark a competitor document's response time
“I want to compare how fast my product page loads versus a competitor — can you measure the TTFB of https://competitor.com/product-overview for me?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/ttfb/dokumentWhen to prefer
Use this endpoint when you specifically need to measure Time to First Byte (TTFB) for a document resource (HTML page, PDF, or other document URL) as a focused server-response-time diagnostic. Prefer this over general page-load tools when you need a single, cost-effective TTFB signal rather than a full performance audit, and when the target is a document object type rather than a stylesheet, script, video, or API response.
Side effects
- URL is not publicly accessible or returns a non-2xx status, leading to an error result
- Malformed or missing 'ziel' field causes a validation error
- Target server is unreachable or times out, resulting in no measurement
- Invalid CSS selector causes fallback to first matching element or error
- URL exceeds the 2048 character limit
