How this service works
Prüft am Objekt api-antwort den Befund Zahl renderblockierender Ressourcen.
Output
Returns an audit result containing the count of render-blocking resources found when loading the specified public URL (API response object). May include details about which resources are blocking rendering.
Example use cases
Render blocker audit for public API
“Can you check how many render-blocking resources show up when loading the API response at https://shop.example.com/api/products? I want to know what's slowing down the initial render.”
Performance monitoring for staging endpoint
“Run a render-blocking resource check on https://staging.myapp.io/api/v2/feed — I'm trying to verify our staging API response doesn't introduce any new render blockers before we go live.”
CI check for render-blocking regressions
“After our last deploy, check https://myservice.com/api/homepage-data for render-blocking resources. I want to know if the count increased compared to what we expect — we're targeting zero blockers.”
Technical details
Endpoint
POSThttps://tempo.halowerk.com/v1/pruef/tempo/blockierer/api-antwortWhen to prefer
Use this endpoint when you specifically need to audit the number of render-blocking resources (blocking JS/CSS) on a URL that serves as an API response object. Prefer it over general page-speed tools when you need a programmatic, per-call count of render blockers that can be embedded in automated CI/CD pipelines or monitoring workflows. It is distinct from sibling endpoints that check other objects (video, image, iframe, script, font) or other metrics (TTFB, TLS handshake time, FCP).
Side effects
- URL is not publicly accessible — returns error indicating unreachable target
- Invalid or malformed URL — validation error on 'ziel' field
- CSS selector matches no element — fallback to first match or error
- Target returns non-HTML content incompatible with render analysis — audit may return zero or error
- Rate limit exceeded — HTTP 429 response
- Network timeout reaching target URL — timeout error
