## 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-main-as-markdown-13f60322
```

Example prompt: Can you grab the main content from https://example.com/article and return it as markdown so I can summarize it?

## When to prefer this

Choose this endpoint when you need to extract only the primary <main> HTML element content from a page in Markdown format, without running a browser. It is ideal for agent pipelines that need clean, structured Markdown output from a single URL at low cost ($0.01/call). Prefer it over full-page scrapers when you specifically want main-section content, and over JSON variants when downstream tools expect Markdown.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty result
- Page has no <main> element — returns an empty list with count of zero
- Page requires JavaScript rendering — content may be missing since no browser is used
- Rate limiting or payment failure — call is not executed and returns payment error
- Malformed URL input — request fails with a validation error

## How this service works

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

## Output

A Markdown-formatted list of all content found within <main> HTML elements on the fetched page, along with a count of how many main elements were found. The response is structured for easy consumption by agents and downstream pipelines.
