## 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-weiterleitung-anteil-moderner-bildformate-9bd84848 -d '<json body>'
```

Example prompt: Can you check what share of images on https://example.com/gallery are served in modern formats like WebP or AVIF — the URL redirects, so make sure you follow the redirect to the actual destination?

## When to prefer this

Use this endpoint when you specifically need to assess modern image format adoption (WebP, AVIF, etc.) on a resource that is accessed via a redirect. It is distinct from direct-URL image format checks because it follows the redirect chain. Prefer this over generic page speed tools when you want a targeted, programmatic, per-object finding on redirect-resolved destinations, especially for automated auditing pipelines or CI checks.

## Known failure modes

- Target URL is unreachable or returns a non-2xx status — endpoint may return an error or empty finding
- URL does not actually redirect — result may not reflect intended redirect-chain behavior
- CSS selector matches no element — first matching element used or empty result returned
- Target page loads images lazily and they are not captured — modern format share may be underestimated
- Non-public or private IP address provided — rejected due to address restrictions

## How this service works

Prüft am Objekt weiterleitung den Befund Anteil moderner Bildformate.

## Output

Returns an audit finding (Befund) indicating the proportion (Anteil) of images using modern formats (e.g. WebP, AVIF) on the object reached via the specified redirect URL, expressed as a ratio or percentage along with diagnostic metadata.
