HUMIA Protocol HUMIA defines a website-first mechanism for publishing a machine- readable cooperation policy for AI agents. A website publishes a JSON policy at /.well-known/humia.json. The policy identifies the origin and expresses site-level conditions for public-content access, selected AI usage purposes, attribution, and optional usage reporting. HUMIA does not replace the Robots Exclusion Protocol, authentication, authorization, licensing, or access-control mechanisms. It is an additional cooperation layer. This document also defines an optional, experimental Humia: discovery record in robots.txt that points HUMIA-aware agents to the canonical policy URI.
