## 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-h4-as-csv-9cf0fe2d
```

Example prompt: Can you extract all the H4 headings from this page — https://example.com/docs — and give me the results as a CSV?

## When to prefer this

Choose this endpoint when you specifically need H4-level headings extracted from a webpage in a CSV format ready for pipelines or spreadsheets. It is ideal for lightweight, no-browser scraping tasks focused on a single heading level. Prefer it over general-purpose scrapers when you want clean, structured CSV output with a count, and when H4 is the relevant semantic level for your content audit, competitive analysis, or document structure mapping.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page has no H4 elements — returns empty CSV with a count of zero
- URL points to a non-HTML resource (e.g. PDF, image) — H4 parsing yields no results
- Malformed or invalid URL provided — request fails immediately
- Page requires JavaScript rendering to display H4 elements — server-side fetch misses dynamic content
- Payment not included or insufficient — returns 402 Payment Required

## How this service works

Extract the page's h4 as csv: fetches the URL, pulls every h4 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 H4 heading text found on the fetched page is a separate row, along with a count of the total number of H4 elements found. The output is structured for direct use in data pipelines, spreadsheets, or downstream processing without requiring a browser.
