World launched AgentKit to link AI agents with verified human identities.
Coinbase integrated its x402 protocol to enable stablecoin micropayments for AI agents.
World ID uses zero-knowledge proofs to confirm human identity without sharing personal data.
Developers can connect multiple AI agents to one verified human account.
The system allows platforms to enforce limits based on a single verified person.

Sam Altman-backed World has launched a new developer toolkit to verify humans behind AI transactions. The company introduced AgentKit to link AI agents with verified human identities. World built the product to work with Coinbase’s x402 protocol for agentic payments.

World and Coinbase Launch AgentKit for Human-Verified AI Payments

World released AgentKit in beta to help developers link AI agents to verified humans. The toolkit integrates with x402, a protocol created by Coinbase and Cloudflare. The system embeds stablecoin micropayments into internet communication layers for automated transactions.

Coinbase Developer Platform head Erik Reppel described the development as a step forward for agentic commerce. He said, “Payments are the ‘how’ of agentic commerce, but identity is the ‘who.’” He added that the system allows agents to operate as legitimate economic participants.

World stated that AI agents now handle bookings and online shopping tasks. The company estimates agentic commerce could reach $3 trillion to $5 trillion by 2030. It also projects that agents could account for up to 25% of U.S. e-commerce activity.

Coinbase founder Brian Armstrong said AI agents will soon outnumber humans in transactions. Binance founder Changpeng Zhao predicted agents will make one million times more payments than people. He stated that agents will use crypto for those transactions.

Very soon there are going to be more AI agents than humans making transactions.

They can’t open a bank account, but they can own a crypto wallet. Think about it.

Identity Layer Targets Agentic Commerce Growth

World designed AgentKit to connect multiple AI agents to one verified human. DC Builder, a research engineer at the World Foundation, explained the identity gap. He said, “Proof of Human addresses this gap.”

A World spokesperson said AgentKit allows developers to link several agents to one person. The spokesperson stated that platforms can enforce limits based on the verified individual. This structure enables controls such as one free trial per person.

Platforms often block automated traffic to prevent abuse and fraud. However, legitimate AI agents face similar restrictions under current systems. AgentKit allows users to delegate their World ID to agents acting on their behalf.

World said the system uses zero-knowledge proofs to protect personal data. Platforms can verify that an agent represents a real person without storing identity details. The company described World ID as a proof-of-human layer that complements other systems.

AgentKit currently relies on Orb-based biometric verification for identity confirmation. World confirmed plans to expand verification methods beyond Orb devices. Future updates will include NFC-enabled passports and IDs through World ID Credentials.

The company reported 17,912,203 verified humans on its real-time meter at publication. World stated that its network ranks among the largest proof-of-personhood systems globally. AgentKit remains in beta as the company develops the next generation of the World ID protocol.
