## 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 xpath-textarea-name-extractor-b7a4f902 -d '<json body>'
```

Example prompt: Can you extract the name attributes of all textarea elements from the HTML form at https://example.com/contact — I need to know what the textarea fields are called?

## When to prefer this

Use this endpoint when you need to specifically extract the name attributes of textarea elements from a page or HTML snippet via XPath, and you want an SSRF-safe, deterministic extraction without spinning up a full browser. Prefer the free sandbox POST /v1/sandbox/xpath-textarea-name first; use this paid endpoint when the sandbox is unavailable or when you need production reliability.

## Known failure modes

- URL is unreachable or returns a non-200 response — extraction fails
- HTML contains no textarea elements — returns empty result
- Page requires JavaScript rendering — static HTML fetch may miss dynamically injected textareas
- Input HTML exceeds 200,000 character limit — request rejected
- URL blocked by SSRF safety rules — request rejected
- Malformed HTML may cause XPath parsing errors

## How this service works

Call when an agent needs name attributes of //textarea via //textarea/@name from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-textarea-name first.

## Output

A list or array of name attribute values extracted from all //textarea elements found in the provided URL or HTML, delivered as structured data from the XPath query.
