## 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-input-field-form-count-inspector-e0240e30 -d '<json body>'
```

Example prompt: Check https://example.com/signup and tell me how many forms are contained in the input field with the CSS selector '#registration-form input.main' — I want to know the form count finding for that specific element.

## When to prefer this

Choose this endpoint when you specifically need to count the number of forms nested within or associated with an input field element on a webpage. It is distinct from page-level form counts or form method inspection — use it when the scope is explicitly the input field object and the finding is form quantity.

## Known failure modes

- Invalid or unreachable URL returns an error indicating the target could not be fetched
- CSS selector matches no element, returning zero or an error for no matching object
- Target page requires authentication or blocks crawlers, resulting in an access error
- Malformed URL or schema validation failure returns a 400-level error
- Network timeout if the target URL is slow to respond

## How this service works

Prüft am Objekt eingabefeld den Befund Zahl enthaltener Formulare.

## Output

Returns a finding (Befund) indicating the number of forms (Formularzahl) contained within the specified input field element on the target URL. The response provides a count value reflecting how many forms are detected inside the queried input element.
