How this service works
Prüft am Objekt iframe den Befund Zeit bis zum ersten Byte.
Output
Returns the measured Time to First Byte (TTFB) for the specified iframe element at the target URL, indicating how long the browser waited before receiving the first byte of the iframe's response. May include timing metrics and pass/fail assessment relative to performance thresholds.
Example use cases
Diagnose slow iframe embed
“The embedded widget on our product page at https://shop.example.com/product seems sluggish — can you measure its TTFB to see if the iframe is the bottleneck?”
Performance audit before launch
“We're about to go live with the site at https://staging.mysite.com — can you check the TTFB on the iframe element with the CSS selector '#partner-widget' to make sure it's within acceptable limits?”
Monitor third-party embed performance
“I need to know how fast the third-party iframe at https://dashboard.example.org/embed is responding — can you run a TTFB check on it for me?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/ttfb/iframeWhen to prefer
Use this endpoint when you specifically need to measure TTFB for an iframe element on a webpage, particularly for diagnosing latency in embedded third-party content, widget loading, or any sub-resource delivered via iframe. Prefer this over generic page-level TTFB checks when the iframe is the suspected performance bottleneck.
Side effects
- Target URL is unreachable or returns a non-200 status — probe cannot be performed
- URL points to a private or non-public IP address — blocked by policy
- CSS selector matches no iframe element on the page — returns error or first-match fallback
- Target site blocks automated requests or requires authentication — measurement fails
- Malformed or too-long URL input — validation error returned
