## 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-cookie-transmission-before-consent-check-7430374c -d '<json body>'
```

Example prompt: Can you check whether https://example.com is transmitting any cookies before the user gives consent — I need to know if we have a pre-consent cookie issue for our GDPR audit.

## When to prefer this

Choose this endpoint when you need to specifically verify whether cookies are transmitted before user consent as part of a GDPR, ePrivacy, or cookie compliance audit. It is specialized for the pre-consent cookie transmission check rather than general cookie counting or label checking, making it the right choice when the legal question is about the timing of cookie transmission relative to user consent.

## Known failure modes

- Invalid or unreachable target URL returns an error or empty finding
- Non-public or internal IP addresses are rejected
- CSS selector matches no element, falling back to first matching object
- Malformed input (URL exceeding 2048 characters) returns a validation error
- Timeout if the target page takes too long to respond

## How this service works

Prüft am Objekt cookie den Befund Übermittlung vor Einwilligung.

## Output

Returns a structured finding indicating whether cookies are transmitted on the target page before the user has provided consent, including details about the object inspected (cookie) and the specific compliance finding detected.
