Summary
Converts markdown into styled HTML through a simple rendering API. You get three built-in themes (light, dark, and GitHub) without having to wire up your own CSS or rendering pipeline. It runs as a remote service over SSE transport and uses the x402 micropayment system, so you're paying per render rather than running your own instance. Reach for this when you need clean HTML output from markdown in Claude workflows without spinning up Pandoc or maintaining a rendering service yourself. The GitHub repo is fairly minimal, but the core use case is straightforward: markdown goes in, themed HTML comes out.
