## 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 extract-h5-as-json-899be8bf
```

Example prompt: Can you pull all the H5 headings from this page — https://example.com/article — and give them to me as a JSON list?

## When to prefer this

Use this endpoint when you need to specifically extract H5-level headings from a web page in a structured JSON format without spinning up a browser. It is ideal for content auditing pipelines, heading hierarchy analysis, and agent workflows that need a targeted, single-element-type extraction at low cost ($0.01/page). Prefer this over full-page scraping tools when only H5 elements are needed, to keep costs and payload size minimal.

## Known failure modes

- URL is unreachable or returns a non-200 status — empty array or error response returned
- Page has no H5 elements — returns array with count of 0
- Invalid or malformed URL provided — request fails with validation error
- Page is JavaScript-rendered (SPA) — H5 elements injected by JS may not be captured since no browser is used
- Rate limiting or firewall on target site blocks the fetch — returns fetch error

## How this service works

Extract the page's h5 as json: fetches the URL, pulls every h5 element and returns them as a JSON array, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.

## Output

A JSON object containing an array of all H5 element text strings found on the fetched page, along with a count of how many H5 elements were discovered. No browser rendering is required; the response is structured and machine-readable.
