Introducing Markdown for Agents

Cloudflare introduces Markdown for Agents, a feature that automatically converts HTML pages to markdown at the network level for AI crawlers and agents.

• •HTML pages consume 4-5x more tokens than markdown equivalents, making markdown critical for efficient AI processing (e.g., a blog post: 16,180 tokens in HTML vs 3,150 in markdown)
• •Enabled zones can serve markdown via HTTP content negotiation using the Accept: text/markdown header, with Cloudflare converting HTML on the fly before delivery
• •Responses include an x-markdown-tokens header indicating estimated token count, useful for context window sizing and chunking strategies
• •Converted responses carry Content-Signal headers (ai-train=yes, search=yes, ai-input=yes) to communicate content usage permissions
• •
