## 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 html-to-markdown-converter-64be83b4 -d '<json body>'
```

Example prompt: Convert this HTML snippet to markdown using ATX-style headings and dash bullet markers: '<h1>Title</h1><ul><li>Item one</li><li>Item two</li></ul><p>Some paragraph text here.</p>'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call HTML-to-Markdown conversion without API keys or subscriptions. Ideal for one-off conversions, agent pipelines processing scraped HTML, or cases where you want turndown-compatible output with control over heading and bullet styles. Prefer over heavyweight document parsers when the input is already valid HTML and you just need clean Markdown.

## Known failure modes

- Missing or empty html body field returns an error
- Invalid headingStyle value (not setext or atx) may cause unexpected output
- Malformed HTML may produce garbled or incomplete markdown
- Payment failure via x402/USDC returns 402 Payment Required
- Very large HTML documents may time out or hit size limits
