Sam Altman’s World has launched AgentKit, a developer toolkit that helps websites verify AI agents are backed by real humans rather than bots. The tool integrates with x402, an open protocol from Coinbase and Cloudflare, allowing AI agents to provide cryptographic proof of human identity during interactions.
The initiative addresses growing concerns in AI commerce as agents take on tasks like booking, shopping, and payments. McKinsey predicts agentic commerce could reach $3 trillion to $5 trillion globally by 2030.
Users can delegate their World ID to an AI agent, enabling it to prove a real person is behind the activity without revealing personal details. This adds a privacy-preserving trust signal alongside payment checks.
Coinbase and Cloudflare introduced x402 last year to enable stablecoin payments directly through web requests, making payment a native part of internet traffic.
World claims its network includes nearly 18 million verified users across 160 countries, offering developers a large base for identity verification without collecting full personal data.
