World launches AgentKit with Coinbase integration to enable human-verified AI agents

The new toolkit from Sam Altman's startup lets AI agents prove they are backed by a unique human while interacting with websites, APIs and other online services.

World, the identity network co-founded by OpenAI CEO Sam Altman, has released AgentKit, a developer toolkit that allows AI agents to prove they are linked to a verified, unique human through World ID when interacting with websites and online services.

The system integrates World ID’s proof-of-human identity with the x402 micropayments protocol started by Coinbase and Cloudflare, allowing agents to pay for access to online resources while presenting cryptographic proof that they are linked to a verified human credential.

The x402 protocol allows agents to pay small fees to access websites, APIs and other services. According to an announcement, the ecosystem has processed more than 100 million payments across applications, APIs and AI agents since launching in 2025.
