## 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 formwerk-script-label-check-c08837c7 -d '<json body>'
```

Example prompt: Check the script element on https://example.com/contact for a valid field label — use CSS selector '#tracking-script' to target it specifically and tell me whether a label is present.

## When to prefer this

Use this endpoint when you specifically need to verify whether a script element on a public webpage has a field label — particularly in the context of form auditing, accessibility checks, or compliance reviews. It is purpose-built for the 'skript' object type and 'Feldbeschriftung' finding, unlike generic HTML scrapers or broader accessibility scanners.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status
- CSS selector matches no element or matches multiple elements (first match used)
- Script element exists but cannot be parsed or evaluated
- Network timeout when fetching the target URL
- Invalid URL format provided in 'ziel' field
- Target resource blocks crawler user agents

## How this service works

Prüft am Objekt skript den Befund vorhandene Feldbeschriftung.

## Output

Returns a structured finding indicating whether the targeted script object on the given URL has a field label (Feldbeschriftung) present, along with details about the inspected element and any relevant audit metadata.
