## 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-field-label-check-04da29b2 -d '<json body>'
```

Example prompt: Check whether the network requests on https://example.com have proper field labels — I need to know if the Feldbeschriftung (field label) finding passes or fails for that page.

## When to prefer this

Use this endpoint when you need to specifically audit whether network request objects on a public webpage carry proper field labels, as part of a web compliance, GDPR, or accessibility workflow. Prefer it over generic crawlers when you need a structured pass/fail finding on label presence for network requests rather than full-page scraping or cookie counting.

## Known failure modes

- Target URL is not publicly accessible or returns a non-200 status
- CSS selector matches zero or more than one element (first match used)
- URL exceeds 2048 characters or is malformed
- Domain or IP is private/non-routable
- Network timeout when fetching the target page
- Ambiguous or missing label finding if page uses dynamic rendering

## How this service works

## Output

Returns an audit finding indicating whether the network request object on the target page has field labels (Feldbeschriftung) present or absent, along with details about the inspected element and its compliance status.
