Identity startup World has released a beta version of Agent Kit, allowing users to link their iris-scan verified World ID to AI agents. The tool aims to help websites distinguish requests from human-directed agents amid rising concerns over AI agent swarms. It builds on iris-scanning technology originally tied to the Worldcoin cryptocurrency.
World, the company behind the Sam Altman-founded Worldcoin launched in 2023, announced the beta of Agent Kit on March 17, 2026. The kit enables users who have verified their identity via iris scans on one of nearly 1,000 physical orbs to attach a cryptographically unique World ID token to their AI agents. Nearly 18 million unique humans have completed this verification process worldwide, with about 18,000 new users in the past week alone. Worldcoin, which offered free tokens for iris scans, continues to exist though its value has fallen below early 2024 peaks, as World pivots focus to World ID tokens stored on phones for secure online identity proofing. Tools like OpenClaw have demonstrated how users can deploy swarms of AI agents for tasks, creating Sybil attack-style overloads akin to DDoS for online services. Agent Kit addresses this by letting websites require AI agents to present a World ID token, confirming a real human directs them. This could limit access to resources such as restaurant reservations, ticket sales, free trials, or bandwidth, while preventing automated abuse in forums and polls. The system relies on the x402 protocol, developed with support from Cloudflare and Coinbase. While some sites use x402 for micropayments to rate-limit agents, World argues that unique World ID tokens cannot be faked by attackers, unlike payments which can be funded in bulk. Adoption remains a hurdle, as widespread use depends on more people undergoing biometric verification amid a chicken-and-egg challenge for online human identity assignment.
