Summary
Converts HTML documents into clean markdown while automatically stripping out scripts and styles. The server operates behind an x402 micropayment system at klymax402.com, so you'll need to handle payment flow to use it. Reach for this when you need sanitized markdown from web content without rolling your own parser or dealing with the messy bits of HTML cleanup. The remote transport uses SSE, which means streaming responses over server-sent events. The GitHub repo is fairly minimal without much documentation visible, but the core use case is straightforward: throw HTML at it, get readable markdown back, and let it handle the cruft removal for you.
