# Markdown to HTML API

[![MCP Server](https://img.shields.io/badge/MCP-server-blue)](https://markdown-to-html.api.klymax402.com/mcp)

Convert Markdown to clean HTML -- headings, lists, code blocks, tables, links, images. Optional full document wrap. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

## Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

```json
{
  "mcpServers": {
    "markdown-to-html": {
      "url": "https://markdown-to-html.api.klymax402.com/mcp"
    }
  }
}
```

## Quickstart -- HTTP (x402)

```bash
curl -X POST "https://markdown-to-html.api.klymax402.com/api/convert" \
  -H "Content-Type: application/json" \
  -d '{"markdown":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```

Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.

## Tools

| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `text_convert_markdown_to_html` | POST | `/api/convert` | $0.003 | Convert markdown text to HTML |

{"html":"<h1>Hello World</h1>\n<p>This is <strong>bold</strong> and <em>italic</em>.</p>","inputLength":42,"outputLength":68}
```
