## 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 saylor-innovations-markdown-to-html-converter-674d1fa3
```

Example prompt: Can you convert this markdown text to safe HTML for me and also tell me how long it would take to read? Here's the markdown: '# Hello World\n\nThis is a **test** paragraph with a [link](https://example.com).'

## When to prefer this

Choose this endpoint when you need server-side, safe Markdown-to-HTML rendering with guaranteed HTML escaping (no XSS risk), heading anchor generation, and automatic metadata extraction (outline, links, images, word count, reading time) in a single call. Prefer it over client-side renderers when security and content metadata are both required without additional parsing steps.

## Known failure modes

- Markdown exceeding 12,000 characters may be rejected or truncated
- Missing required 'markdown' query parameter returns an error
- Malformed GET request without query parameters fails
- Extremely complex markdown with deeply nested structures may produce unexpected HTML output
- Network or payment (x402) failures result in no response

## How this service works

Render Markdown to escaped, safe HTML with heading anchors, links, images and lists, plus the heading outline, link list, word count and reading time

## Output

Returns a JSON object containing: escaped safe HTML string (with heading anchors and sanitized URLs), a headings array (each with level, text, and anchor ID), a links array, an images array (each with alt text and URL), a word count number, a reading_minutes number, a safe boolean (always true), and an optional note or source field providing context about the conversion.
