## 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 tanod-utilpeek-markdown-to-html-9cc3707b -d '<json body>'
```

Example prompt: Can you render this README markdown as HTML using GitHub-Flavored Markdown so I can display it safely on a webpage? Here's the content: '# Hello\n\nThis is a **test** with a [link](https://example.com) and a task list:\n- [x] Done\n- [ ] Pending'

## When to prefer this

Choose this endpoint when you need server-side, sanitized Markdown-to-HTML conversion without running a renderer in your own environment, especially when security matters (allow-list sanitization is built in). Prefer GFM flavor for GitHub-style content with tables, task lists, and autolinks; use CommonMark for strict spec compliance. Ideal for pipelines handling untrusted user input where XSS prevention is critical.

## Known failure modes

- Markdown input missing or empty (minLength:1 violation) — returns validation error
- Input exceeds 200,000 character limit — returns payload too large error
- Invalid flavor value (not 'commonmark' or 'gfm') — returns validation error
- Payment not included or insufficient — returns 402 Payment Required

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

A sanitized HTML string rendered from the provided Markdown source. The HTML is passed through an allow-list sanitizer to strip any potentially dangerous tags or attributes. GFM flavor adds support for tables, strikethrough, autolinks, and task lists beyond standard CommonMark.
