## 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 agentshelf-profile-form-method-extractor-358938e9 -d '<json body>'
```

Example prompt: Can you check what HTTP method the form on https://example.com/profile uses — I need to know if it submits via GET or POST before I automate it.

## When to prefer this

Use this endpoint when you need to programmatically determine the HTTP method attribute of form elements on a public webpage or from raw HTML, especially in agentic workflows that automate form interactions. The SSRF-safe fetch makes it suitable for passing arbitrary user-supplied URLs without risking internal network exposure. Prefer the unpaid sandbox endpoint (/v1/sandbox/profile-form-method) for testing; use this paid endpoint for production use where reliability matters.

## Known failure modes

- URL unreachable or returns non-200 response — fetch error returned
- URL blocked by SSRF protection (private/internal IP ranges) — rejected with error
- No form elements found in the HTML — empty or null result
- HTML too large (>200,000 characters) — request rejected
- Malformed HTML where form method attribute is absent — empty result
- Invalid or too-short URL (<8 chars) — validation error

## How this service works

Call when an agent needs form method values extracted from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/profile-form-method first.

## Output

Returns the value(s) of the method attribute found in form elements on the given page or HTML — typically 'get', 'post', or other HTTP method strings. If a URL is provided, the service fetches the page (SSRF-safe) and parses it; if raw HTML is provided, it parses that directly.
