## 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-xpath-h5-text-extractor-8efde3d7 -d '<json body>'
```

Example prompt: Can you grab all the h5 heading texts from https://example.com/article — I want to see every level-5 subheading on that page?

## When to prefer this

Use this endpoint when you specifically need to extract <h5> heading text from a public web page or raw HTML, and you want a lightweight, SSRF-safe, deterministic XPath-based extraction without LLM processing. Prefer this over general HTML-to-text or markdown conversion when you only need h5 nodes. Use the free sandbox endpoint /v1/sandbox/xpath-h5 first if available.

## Known failure modes

- No h5 elements found — returns empty list
- URL fetch fails due to SSRF protection blocking private/internal addresses
- URL unreachable or returns non-200 status — fetch error returned
- HTML input exceeds 200,000 character limit — request rejected
- Neither url nor html provided — validation error
- URL longer than 2048 characters — rejected

## How this service works

Call when an agent needs text of //h5 via //h5 from a public page or HTML (SSRF-safe). Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/xpath-h5 first.

## Output

A list of text strings, one per <h5> element found in the page or HTML, extracted via XPath (//h5). Returns the inner text of each matching element. If a URL is supplied, the page is fetched in an SSRF-safe manner before extraction.
