## 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 api-strale-io-de78431c
```

Example prompt: Can you convert this markdown text to styled HTML using the dark theme? Here's the markdown: '# Hello World\n\nThis is a **bold** statement and here is a [link](https://example.com).'

## When to prefer this

Use this endpoint when you need to render markdown as visually styled HTML with inline CSS — especially useful for embedding in emails, PDFs, or environments where external stylesheets are not supported. Prefer this over DIY markdown parsers when you need themed output (light/dark/plain) without managing CSS yourself.

## Known failure modes

- Missing 'markdown' query parameter returns an error
- Invalid theme value (not light/dark/plain) may cause fallback or error
- Extremely large markdown payloads may exceed query string limits
- Malformed markdown may produce unexpected HTML output
- Payment failure via x402 protocol returns 402 status
