## 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-pixel-form-method-check-a764c700 -d '<json body>'
```

Example prompt: Can you check what HTTP form method the tracking pixel on https://example.com/landing uses? Use the CSS selector '#tracking-pixel' if you need to isolate it.

## When to prefer this

Use this endpoint when you specifically need to audit or validate the HTTP form submission method used by a pixel element on a webpage, as opposed to checking the overall page's forms or other element types. It is distinct from the sibling endpoint that checks form methods at the page level — use this when your target is a pixel object specifically.

## Known failure modes

- Invalid or unreachable URL returns an error indicating the target could not be fetched
- CSS selector matches no element or multiple elements — first match used or error returned
- Non-public/private IP addresses rejected
- URL exceeds maximum length of 2048 characters
- Target page does not contain a detectable pixel form element, resulting in empty or null finding

## How this service works

Prüft am Objekt pixel den Befund verwendete Formularmethode.

## Output

Returns a structured finding (Befund) indicating the HTTP form method (e.g. GET, POST) used by the identified pixel element on the target URL, along with details about the inspected object.
