World ID wants you to put a cryptographically unique human identity behind your AI agents

World, the identity startup behind WorldCoin, launched Agent Kit beta, a system that uses iris-scanning technology to verify humans are directing AI agents and prevent mass automated attacks on websites. The tool cryptographically ties AI agent activity to a unique identity token stored on users' phones, addressing the problem of Sybil attacks where thousands of coordinated agents flood services with requests. World is leveraging its existing World ID iris-scanning infrastructure—the same technology that powered its 2023 cryptocurrency giveaway—to authenticate human control over AI automation. The pivot marks a shift away from WorldCoin's struggling cryptocurrency toward identity verification as the company's core business focus.
