## 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-cookie-label-checker-a49048b1 -d '<json body>'
```

Example prompt: Can you check whether the cookie consent form on https://example.com has proper field labels present? Use the CSS selector '#cookie-banner' to target just that element.

## When to prefer this

Use this endpoint when you specifically need to audit whether cookie consent banners or cookie-related form objects have proper field labels — distinct from general form label checks or other cookie property audits like submission method or tracking pixel targets.

## Known failure modes

- URL is not publicly accessible or returns non-200 status
- CSS selector matches no elements or is invalid
- Target page blocks automated access (bot protection)
- Cookie object not found on the page
- Network timeout reaching the target URL
- Input URL exceeds maximum length of 2048 characters

## How this service works

Prüft am Objekt cookie den Befund vorhandene Feldbeschriftung.

## Output

Returns a structured finding indicating whether field labels are present on the cookie object at the target URL, including pass/fail status and details about the labeling state of cookie-related form fields.
