## 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-h1-as-json-31a6bdc6
```

Example prompt: Can you pull all the H1 headings from https://example.com and give them to me as JSON so I can see what the page's main heading says?

## When to prefer this

Choose this endpoint when you need a fast, structured, server-side extraction of H1 headings from a web page without spinning up a headless browser. It is ideal for SEO audits, content pipelines, and agent workflows that need only the H1 element in clean JSON format at low cost ($0.01/page). Prefer alternatives if you need other HTML elements, full-page content, or JavaScript-rendered pages.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty array
- Page has no H1 elements — returns an empty array with count 0
- JavaScript-rendered pages where H1 is injected client-side may not be captured since no browser is used
- Invalid or malformed URL input — likely results in an error response
- Rate limiting or access restrictions on the target page may prevent fetching

## How this service works

Extract the page's h1 as json: fetches the URL, pulls every h1 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 H1 element text strings found on the page, along with a count of how many H1 elements were found. No browser rendering required — the fetch is server-side.
