## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tempo-halowerk-com-document-loaded-resources-count-check-248a70e6 -d '<json body>'
```

Example prompt: Can you check how many resources are loaded by the document at https://example.com and tell me the total resource count?

## When to prefer this

Use this endpoint when you specifically need to measure the number of HTTP resources loaded by a document/HTML page, as opposed to checking time-based metrics (TTFB, render start) or other resource types (video, image, script). It is distinct from sibling endpoints that check scripts or iframes — this targets the document object specifically. Prefer this when auditing overall page request bloat or comparing resource counts before and after optimization.

## Known failure modes

- Target URL is not publicly accessible — returns an error or unreachable status
- Invalid or non-matching CSS selector — falls back to first matching element or returns an error
- URL exceeds maximum length of 2048 characters — validation error
- Target page requires authentication and is not publicly reachable — audit cannot complete
- Network timeout reaching the target URL — returns a timeout error
- Malformed URL format — returns a validation error

## How this service works

Prüft am Objekt dokument den Befund Zahl geladener Ressourcen.

## Output

Returns a performance finding object indicating the count of resources loaded by the target document, enabling assessment of whether the page over-fetches assets. The result reflects the 'Zahl geladener Ressourcen' (number of loaded resources) metric for the specified document object.
