Html To Markdown X402 is an MCP server that converts HTML into clean Markdown text, stripping scripts and styles while preserving headings, links, lists, and images. It operates on a pay-per-call model via the x402 protocol (USDC on Base L2), requiring no API key, signup, or rate-limit walls. It is part of the klymax402 marketplace of 100 x402 micropayment APIs for AI agents.
Add the server URL https://html-to-markdown.api.klymax402.com/mcp to your MCP client config (e.g., Claude Desktop, Cursor, ElizaOS). Alternatively, call the HTTP endpoint directly with a POST request—any x402-aware client handles the payment challenge automatically.

The only required parameter is `html` (a string). The server returns a JSON object containing the converted markdown, input length, output length, and a list of stripped elements.
`<script>` and `<style>` elements are stripped. All other content (headings, links, lists, images) is preserved in the markdown output.
This tool is not for converting markdown to HTML (use `text_convert_markdown_to_html`), web scraping with fetching (use `web_scrape_to_markdown`), or PDF generation (use `document_generate_pdf`). It only converts provided HTML.
Add the following to your client’s `mcpServers` config: `"html-to-markdown": { "url": "https://html-to-markdown.api.klymax402.com/mcp" }`. No authentication or additional keys are required.
