## 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 halowerk-formwerk-pixel-consent-state-check-14ff7183 -d '<json body>'
```

Example prompt: Check the consent state of the tracking pixel on https://example.com — I need to know if it has a valid Einwilligung (consent) before it fires, and you can target the pixel using the CSS selector '#tracking-pixel'.

## When to prefer this

Use this endpoint when you need to specifically validate the consent state of a pixel object on a webpage, particularly for GDPR or ePrivacy compliance audits. It is more targeted than general cookie or network request consent checks — choose it when the concern is whether a tracking pixel fires with or without user consent. Prefer sibling endpoints for checking forms, banners, cookies, or network requests instead.

## Known failure modes

- Invalid or unreachable URL returns an error or empty result
- CSS selector matches zero or multiple elements — first match used, or error if none found
- Pixel not present on target page results in no finding
- Private or non-public IP/domain rejected
- Malformed input schema returns validation error
- Timeout if the target URL is slow to respond

## How this service works

Prüft am Objekt pixel den Befund vorhandenen Einwilligungszustand.

## Output

Returns a finding (Befund) indicating whether the tracked pixel object has a present and valid consent state (Einwilligung), allowing compliance assessment of the pixel's behavior relative to user consent requirements.
