## 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-network-request-third-party-domain-count-check-392ecffd -d '<json body>'
```

Example prompt: Can you check how many third-party domains are contacted when loading https://example-shop.com — I want to know if they're reaching out to a lot of external trackers during a network request?

## When to prefer this

Use this endpoint when you need a specific numeric count of third-party (foreign) domains contacted during a network request to a given URL, as part of web privacy audits, GDPR compliance checks, or tracking exposure assessments. It is distinct from full cookie or script analysis endpoints on the same platform and focuses specifically on outbound network-level domain contact count.

## Known failure modes

- Target URL is unreachable or returns an error — request fails or returns zero results
- Non-public or private IP addresses rejected — input validation error
- CSS selector matches no element — falls back to first match or returns empty result
- Target URL exceeds 2048 character limit — input validation error
- Timeout if target site is slow or unresponsive — may return incomplete count

## How this service works

## Output

Returns the count (Zahl) of third-party (foreign) domains contacted during a network request made to the specified target URL or domain. The response reflects how many distinct external domains were reached as part of loading or processing the given resource.
