## 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-netzwerkanfrage-zahl-bermittelter-datenfelder-c6920e06 -d '<json body>'
```

Example prompt: Can you check how many data fields are being transmitted in the network requests on https://example.com — I need an audit of field counts for compliance purposes.

## When to prefer this

Choose this endpoint when you need to specifically count the number of data fields transmitted in network requests originating from a webpage, particularly for GDPR data minimization checks or privacy compliance audits. It is distinct from sibling endpoints that check cookies set, consent state presence, or pre-consent submission behavior — this one focuses exclusively on field count in network requests.

## Known failure modes

- Target URL is unreachable or returns a non-2xx status — audit cannot be completed
- Invalid or non-public URL provided — validation error returned
- CSS selector matches no element or multiple elements — first match used or error if none found
- Network request produces no observable data fields — count of zero returned
- Rate limit exceeded — 429 response
- Malformed input schema — 400 bad request

## How this service works

Prüft am Objekt netzwerkanfrage den Befund Zahl übermittelter Datenfelder.

## Output

Returns a finding indicating the count (number) of data fields transmitted in the network requests observed at the target URL or element. This allows privacy and compliance teams to assess data minimization and detect excessive field transmission.
