## 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 agent402-tools-html-to-markdown-converter-056fa7b4 -d '<json body>'
```

Example prompt: Can you convert this HTML snippet I already have into clean markdown? Here's the HTML: '<h1>Hello World</h1><p>This is a <strong>test</strong> paragraph with a <a href="https://example.com">link</a>.</p>'

## When to prefer this

Use this endpoint when you already have raw HTML in memory and need to convert it to Markdown without fetching any URL. If you need to fetch a live URL and convert it, use the /api/extract endpoint instead. Prefer this over manual regex stripping when clean, structured Markdown output is required.

## Known failure modes

- HTML input exceeds 100KB limit — request rejected
- Malformed or unparseable HTML — may return partial or empty markdown
- Missing 'html' field in request body — validation error
- Payment not included or invalid — 402 payment required response

## How this service works

Convert an HTML fragment or document you already have into clean markdown. (To fetch + convert a live URL, use /api/extract.)

## Output

Returns clean Markdown text converted from the provided HTML input, preserving headings, links, bold/italic formatting, lists, and other structural elements in standard Markdown syntax
