Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-gesamtladezeit-f-r-bild-ecf66c0e -d '<json body>'
```

Example prompt: Can you check the total load time for the hero image on https://example.com/hero.jpg and tell me how long it takes to fully load?

## When to prefer this

Use this endpoint when you specifically need to measure the end-to-end total load time of an image resource at a public URL. It is purpose-built for image objects (as opposed to documents, scripts, fonts, or API responses which are handled by sibling endpoints on the same service). Prefer this over generic web performance tools when you need a lightweight, per-image load time check that integrates directly into an agent workflow.

## Known failure modes

- Non-public or inaccessible image URL returns an error or timeout
- Invalid or malformed URL causes a validation error
- Image resource not found (404) results in a failed check
- CSS selector matches no element if selector is specified
- Rate limiting or payment failure (402) blocks the request

## How this service works

Prüft am Objekt bild den Befund Gesamtladezeit.

## Output

Returns a performance finding (Befund) for the 'Gesamtladezeit' (total load time) of the specified image resource, including the measured total load duration in milliseconds or similar time unit, enabling assessment of image load performance at the given URL.
