WorldAEO — Agent-Readable Surface
The web is built for humans. An agent that wants to read a site or a piece of media today must render it, scroll, wait, screenshot and run a vision model on pixels — minutes of work, thousands of image tokens and a guess at the end. No agent should be required to screenshot to access, review or form a conclusion on a site or its media. Every site publishes, once, a compiled and sealed machine-native surface; an agent discovers it in one HEAD, verifies the seal offline and answers from evidenced claims in milliseconds.
How it works
One request to any page or media URL returns Agent-Surface, Agent-Discovery and WorldAuth-Seal headers.
/.well-known/worldaeo.json lists every artifact with hash and bytes, the seal (both legs and public keys) and the score.
The agent rebuilds the seal body from the artifact hashes and checks Ed25519 and ML-DSA-65 offline. Any mismatch fails closed.
Questions are answered from answers.json, facts and page sections — grounded, with ids — never from pixels.
