World launches AgentKit to verify human users behind AI agents

World, the iris-scanning identity project co-founded by Sam Altman, has launched a developer toolkit called AgentKit, CoinDesk reported. The toolkit allows AI agents to carry cryptographic proofs verifying they are operated by a real user via World's World ID system. The launch addresses growing concerns about identity verification as AI agents are increasingly used for online transactions and shopping. AgentKit aims to solve this by linking multiple agents to a single, verified human. The system integrates with x402, a protocol developed by Coinbase and Cloudflare. The x402 protocol enables agent-to-agent payments by applying stablecoin micropayments to the internet's communication layer, allowing AI agents and software to transact without human intervention. By implementing x402, World aims to establish AI agents as verifiable economic participants rather than just suspicious automated traffic.
