## 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-syntexa-ch-xpath-select-name-7e56c4a8 -d '<json body>'
```

Example prompt: Can you extract all the 'name' attributes from the select/dropdown elements on https://example.com/contact-form so I know what form fields I'm working with?

## When to prefer this

Use this endpoint when you need specifically the 'name' attributes of <select> elements from a page or HTML blob, and you want a deterministic, SSRF-safe extraction without needing to run your own XPath engine. Prefer this over general scraping tools when you only need form dropdown names and want a guaranteed structured result. Note the description recommends trying the unpaid sandbox endpoint first (POST /v1/sandbox/xpath-select-name) before paying $0.009 USDC.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page contains no <select> elements — returns an empty list
- HTML string exceeds 200,000 character limit — request rejected
- URL blocked due to SSRF safety restrictions — access denied
- Malformed HTML that prevents XPath evaluation — may return empty or partial results
- Input too short (under 8 chars for URL) — validation error

## How this service works

Call when an agent needs name attributes of //select via //select/@name from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/xpath-select-name first.

## Output

A list of name attribute values extracted from all <select> elements found in the provided URL's page source or raw HTML, derived via the XPath expression //select/@name.
