Output
Returns a performance finding indicating the total number of bytes transferred when fetching the specified image resource, helping identify whether the image is within acceptable weight thresholds for web performance.
Example use cases
Image weight audit for landing page
“Check the transferred byte size of the product image at https://shop.example.com/products/main.jpg — I want to see if it's contributing to slow page loads.”
Selecting a specific image on a page
“Measure how many bytes are transferred by the image matching the CSS selector '.banner-img' on https://myblog.example.com — I need to know its transfer weight.”
Monitoring image payload over time
“I want to track the transferred bytes for the image at https://cdn.example.com/assets/logo.png — can you check its current byte weight so I can compare it to last week?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/gewicht/bildWhen to prefer
Choose this endpoint when you specifically need to measure the transferred byte size of an image resource on a webpage, as opposed to measuring total page weight or loading time. It is ideal for targeted image optimization audits where you want to isolate the payload size of a single image asset.
Side effects
- URL is not publicly accessible or returns a non-200 HTTP status
- Provided CSS selector matches no image element or is ambiguous
- Image resource is blocked by authentication or access restrictions
- Request times out if the target server is unreachable
- Invalid or malformed URL input causes a validation error
