## 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 uos-genesis-html-to-markdown-converter-0d8944b0 -d '<json body>'
```

Example prompt: Take this HTML I grabbed from the page — `<h1>Welcome</h1><p>This is a <strong>test</strong> paragraph.</p>` — and convert it to clean Markdown for me.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call HTML-to-Markdown conversion without setting up a local library or managing infrastructure. Ideal for agent pipelines that scrape web content and need to normalize it into Markdown for LLM consumption, note-taking, or documentation. Prefer it over general-purpose text strippers when you want to preserve semantic structure (headings, lists, links, emphasis) rather than just extracting plain text.

## Known failure modes

- Malformed or unparseable HTML may produce garbled or incomplete Markdown output
- Deeply nested or non-standard HTML structures may not convert cleanly
- Very large HTML documents may time out or be rejected
- Missing or empty request body returns an error
- Unsupported HTML elements may be silently dropped or passed through as raw text
