## 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-css-input-type-extractor-bf1d0520 -d '<json body>'
```

Example prompt: Can you extract all the input[type] values from the forms on https://example.com/signup — I want to know what types of fields they use, like text, email, password, etc.

## When to prefer this

Use this endpoint when you need to programmatically extract input[type] values from a live public URL or raw HTML and want SSRF protection built in. Prefer the free POST /v1/sandbox/css-input-type endpoint first if available. Choose this over general-purpose HTML scrapers when you specifically need input element type enumeration without running your own browser or parser.

## Known failure modes

- URL is private/internal (SSRF-blocked) — returns error rejecting non-public addresses
- URL is unreachable or returns non-200 — fetch failure error
- HTML exceeds 200,000 character limit — payload too large error
- URL string shorter than 8 characters — validation error
- No input elements found — returns empty list
- Malformed HTML — parser may return partial or empty results

## How this service works

Call when an agent needs input types via input[type] from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/css-input-type first.

## Output

A list of distinct or all input[type] attribute values found in the page or HTML, such as 'text', 'email', 'password', 'hidden', 'checkbox', 'radio', 'submit', etc., parsed from input elements via CSS selector matching.
