## 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-submission-target-domain-check-130998d7 -d '<json body>'
```

Example prompt: Check the cookies on https://example.com/signup to find out which domain the form on that page is actually submitting data to.

## When to prefer this

Use this endpoint when you need to specifically determine the submission target domain as observed through cookies on a web page, particularly for privacy audits, GDPR compliance checks, or security reviews. Prefer this over sibling endpoints (banner, iframe, script, network request) when cookie-based form submission tracking is the focus, and over the 'number of forms' or 'form method' cookie endpoints when the domain destination is the key concern.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint returns an error or empty finding
- No cookies found on the target page — result may be empty or indicate absence of cookie-based submission data
- CSS selector matches zero elements — first matching element used or error returned
- Target domain is private or non-public IP — rejected per input validation
- URL exceeds 2048 character limit — input validation error

## How this service works

Prüft am Objekt cookie den Befund Zieldomain der Übermittlung.

## Output

Returns an analysis of the cookie object on the target page, identifying the domain to which the form submission is directed. The result includes details about the submission target domain as detected through cookie inspection.
