RFC 9110: The New Semantic Internet

You do not need a new wrapper protocol to make the web readable to AI agents. RFC 9110 Section 12 (HTTP Semantics: Content Negotiation) already defines how a single canonical URI serves visual HTML to a human browser and clean, token-efficient Markdown (Accept: text/markdown) to an autonomous agent.

Test proactive content negotiation against this very origin right now:

curl -sI -H "Accept: text/markdown" https://rfc9110.org

Inspect the reference harness installer with less (scroll with j and k, quit with q):

curl -fsSL https://rfc9110.org | less

When you are ready to run the local RFC 9110 verification lab in ~/rfc9110:

curl -fsSL https://rfc9110.org | bash
