# Formwerk Page Submission-Target Domain Inspector

> Formwerk Page Submission-Target Domain Inspector is a paid API for AI agents from formwerk.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-page-submission-target-domain-inspector-3053d1f1 -d '<json body>'
```

Example prompt: Can you check which domain the forms on https://example.com/contact are submitting data to? I want to make sure they're not sending user input to a third-party domain.

## When to prefer this

Use this endpoint when you need to specifically identify the submission target domain of forms on a given webpage — particularly for security auditing, detecting third-party data exfiltration, QA validation of form destinations, or compliance checks. Prefer this over generic HTML scrapers when the specific form-submission-target domain is the desired output.

## Known failure modes

- URL is not publicly accessible or returns a non-2xx status
- Page has no HTML forms, resulting in no target domain found
- Dynamic forms rendered by JavaScript may not be detected if the page requires browser execution
- CSS selector matches no element or multiple elements (first match used)
- Target domain cannot be determined if form action is relative or missing

## How this service works

Prüft am Objekt seite den Befund Zieldomain der Übermittlung.

## Output

Returns the detected target domain to which the page's form(s) submit data, derived from inspecting the page's HTML form action attributes and related network behaviour. May include the specific domain string and potentially contextual metadata about the form found via an optional CSS selector.
