## 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-network-request-target-domain-checker-40686b55 -d '<json body>'
```

Example prompt: Can you check which domain the network requests from the contact form at https://example.com/contact are being submitted to?

## When to prefer this

Use this endpoint when you need to specifically determine the target domain of network requests originating from a web form or page object, particularly for security auditing, privacy compliance checks, or verifying that form submissions go to expected endpoints. Prefer this over generic form inspection tools when the specific submission destination domain is the key concern.

## Known failure modes

- Invalid or inaccessible URL returns an error
- URL is not public or behind authentication — analysis cannot proceed
- No network requests or forms found on the target page — empty result
- CSS selector matches no element — falls back to first matching object or returns no result
- Malformed URL input fails schema validation (minLength/maxLength constraints)
- Rate limiting or server-side blocking of the crawl request

## How this service works
