How this service works
Prüft am Objekt iframe den Befund übertragene Bytemenge.
Output
Returns a performance finding indicating the total number of bytes transferred by the specified iframe element when the target URL is loaded, allowing assessment of network payload weight for that embedded resource.
Example use cases
Audit third-party iframe payload
“Check the transferred byte size of the iframe at https://shop.example.com/product — it's the one matching selector '#partner-widget' — I want to know if it's adding too much network weight.”
Performance baseline for embedded content
“I'm auditing my landing page at https://landing.mybrand.com for performance — can you measure how many bytes the embedded iframe transfers so I can see its impact?”
Monitor iframe weight after vendor update
“Our ad vendor just updated their iframe embed on https://news.example.com — can you re-check the transferred byte size of the iframe using selector '.ad-frame' to see if the payload grew?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/gewicht/iframeWhen to prefer
Use this endpoint when you specifically need to measure the byte transfer size of an iframe element on a web page, such as when auditing third-party embeds, ad widgets, or partner iframes for network performance impact. Prefer this over generic page-weight tools when you want granular iframe-level measurement rather than whole-page metrics.
Side effects
- Target URL is not publicly accessible (returns 4xx/5xx or requires authentication)
- CSS selector matches zero elements on the page, returning an error or empty result
- URL is malformed or exceeds 2048 characters
- Target iframe does not transfer measurable data (e.g., blocked by CORS or browser policy)
- Network timeout when probing the target URL
