Summary
Converts markdown to HTML through a simple remote API, handling headings, lists, and code blocks. Operates on the x402 micropayment network, so you'll need to handle those payment flows if you're building something that needs on-demand rendering. The server runs at markdown-to-html.api.klymax402.com and connects via SSE transport. Reach for this when you need markdown conversion without bundling a parser locally, though the GitHub repo is sparse on implementation details. The x402 payment requirement means this is geared toward metered usage rather than one-off conversions.
