World, Sam Altman's identity verification startup, released AgentKit, a beta tool that allows e-commerce websites to verify that real humans are behind AI agents making purchases on their behalf. The system uses World ID derived from iris scans via World's Orb device and integrates with the x402 blockchain payment protocol developed by Coinbase and Cloudflare. Users register their AI shopping agents with their World ID, which then communicates to websites that a verified human approves the agent's purchasing decisions. This addresses growing concerns about fraud and abuse as AI agents increasingly handle online shopping for consumers.
