## 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-action-extractor-fbb4d290 -d '<json body>'
```

Example prompt: Can you extract the form action value from this page — https://example.com/profile — so I know where the profile update form submits to?

## When to prefer this

Use this endpoint when an agent needs to programmatically discover where an HTML form submits its data, either from a live public URL or a raw HTML string, and requires SSRF-safe fetching. Prefer the free sandbox endpoint (/v1/sandbox/profile-form-action) for testing. Choose this over a general-purpose web scraper when you specifically need form action values with SSRF protection built in.

## Known failure modes

- URL is internal or private (SSRF blocked) — request rejected for safety
- URL is unreachable or returns non-200 status — extraction fails
- No form or form action attribute found in the HTML — empty or null result
- HTML input exceeds 200,000 character limit — request rejected
- URL string shorter than 8 characters or longer than 2048 characters — validation error
- Both url and html fields omitted — missing required input error

## How this service works

Call when an agent needs form action values extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-form-action first.

## Output

Returns the extracted form action attribute value(s) found in the HTML of the given URL or raw HTML string, indicating where the form(s) submit their data. Useful for understanding form submission targets without manually parsing HTML.
