## 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-h3-as-csv-b4eceed7
```

Example prompt: Can you extract all the H3 headings from https://example.com/blog and give them to me as a CSV?

## When to prefer this

Use this endpoint when you need only the H3 headings from a page in a structured, CSV-ready format without a full browser. It is ideal for lightweight pipelines and agents that need structured heading data quickly and cheaply ($0.01/page). Prefer this over full-page scrapers when H3 elements are the only content needed, saving cost and complexity.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no H3 elements — returns an empty CSV with a count of zero
- JavaScript-rendered H3 elements may not be captured since no browser is used
- Malformed or extremely large pages may cause incomplete extraction
- Payment not processed — endpoint returns 402 before extraction begins

## How this service works

Extract the page's h3 as csv: fetches the URL, pulls every h3 element and returns them as CSV rows, with a count. Structured, one-element-type extraction for agents and pipelines; no browser needed. $0.01 per page.

## Output

A CSV-formatted response where each row contains one H3 element found on the page, plus a total count of H3 elements extracted. No browser or JavaScript rendering is required.
