How this service works
Prüft am Objekt schrift den Befund übertragene Bytemenge.
Output
Returns a performance finding (Befund) indicating the transferred byte size (Bytemenge/Gewicht) of the specified font resource, enabling assessment of whether the font payload is appropriately sized for web performance.
Example use cases
Font weight audit for performance report
“I'm putting together a web performance report — can you check the transferred byte size of the font file at https://myshop.com/assets/fonts/brand.woff2 and tell me how heavy it is?”
Monitoring font size after compression update
“I just applied Brotli compression to our fonts — can you measure the transferred byte size of https://myblog.com/fonts/heading.woff2 to verify it's actually smaller now?”
Diagnosing slow font load on a page
“My page feels slow and I suspect the fonts are too large. Can you check the transferred size of the font loaded via the first @font-face on https://portfolio.example.com and tell me how big it is?”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/gewicht/schriftWhen to prefer
Use this endpoint when you specifically need to measure the transferred byte size of a font resource (woff, woff2, ttf, etc.) at a public URL. It is purpose-built for font payload weight checks as part of a web performance audit, distinct from sibling endpoints that measure connection time or TTFB for fonts, or that analyze images and scripts. Prefer this when diagnosing whether a font file is too large or verifying compression has reduced font payload size.
Side effects
- URL is not publicly accessible — returns error or no result
- Target resource is not a font file — finding may be invalid or empty
- CSS selector matches no element or multiple elements — first match used or error returned
- DNS resolution failure for the provided domain
- Request timeout if the remote server is slow to respond
- Invalid URL format exceeding maxLength of 2048 characters
