Example use cases
Landing page image format audit
“Audit https://shop.mybrand.com/landing and tell me what percentage of images are using modern formats like WebP or AVIF versus old formats like JPEG or PNG.”

Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/bildformat/seiteWhen to prefer
Use this endpoint when you need to specifically measure the adoption of modern image formats (WebP, AVIF, etc.) on a given web page, as part of a performance or optimization audit. It is purpose-built for page-level image format analysis rather than general performance scoring or full Lighthouse-style audits.
Side effects
- Invalid or unreachable URL returns an error — ensure the target is a publicly accessible HTTPS address
- CSS selector matching zero or multiple elements may fall back to the first match or return an error
- Pages behind authentication or paywalls may not be fully analyzable
- Rate limiting or bot protection on the target page may cause incomplete results
- Malformed input schema (missing required 'ziel' field) returns a validation error
