Implement Markdown Content Negotiation

Support Accept: text/markdown content negotiation so agents can request markdown versions of your pages. See llmstxt.org and Markdown for Agents.

Requirements

  • When a request includes Accept: text/markdown, return a markdown representation of the page
  • Set Content-Type: text/markdown on the response
  • HTML remains the default for requests without the markdown accept header
  • Include an x-markdown-tokens header with the token count if available

Markdown for Agents enables this automatically for Cloudflare zones — no application code changes needed.
