Overview
- Sites on Cloudflare that opt in now serve on-the-fly Markdown when clients send Accept: text/markdown, with responses including an x-markdown-tokens estimate.
- Cloudflare cites an example dropping a page from about 16,180 HTML tokens to roughly 3,150 in Markdown, an estimated 80 percent reduction.
- Converted responses carry a Content-Signal header set by default to ai-train=yes, search=yes, ai-input=yes, while robots.txt Content Signals remain voluntary for bots.
- The feature is available today in Beta at no cost for Pro, Business, Enterprise, and SSL for SaaS customers and can be enabled per zone in the dashboard.
- Cloudflare reports coding agents like Claude Code and OpenCode already request Markdown, with new Radar analytics surfacing agent content-type consumption and alternative tools such as Workers AI .toMarkdown() and a Browser Rendering /markdown API offered for other conversion paths.
