Tools for Humanity, the company behind World and co-founded by OpenAI CEO Sam Altman and Alex Blania, launched AgentKit on March 17 as a developer toolkit that lets AI agents cryptographically prove they are acting on behalf of a verified human. The system combines World's iris-based identity credential with Coinbase's x402 payment protocol, targeting a growing problem in agentic commerce: no one can reliably tell whether an autonomous bot is backed by a real person or running unchecked.

The release arrives as AI agents increasingly handle real-world transactions. They book reservations, purchase concert tickets, and access paid APIs with minimal human supervision. Research firm DataDome found that 80% of AI agents do not properly identify themselves online, and the same share of websites do not attempt to verify agent identity. A federal judge in early 2026 blocked Perplexity's browser from making Amazon purchases on behalf of users, illustrating the legal and platform-level friction that unverified autonomous agents are generating.

AgentKit addresses this through a delegation model. A user's World ID, generated from an iris scan at one of World's Orb devices, can be assigned to an AI agent. That agent then carries a cryptographic credential proving human backing when it contacts a website or service. A senior World executive described the arrangement as analogous to granting the agent "power of attorney." Erik Reppel, head of developer platform at Coinbase, said the technology allows platforms to determine "whether the request is coming from a human or an agent, or an agent tied to a human." The identity check can be requested alongside a micropayment, or instead of one, on the x402 stack.

The x402 protocol, which Coinbase first released in May 2025 and for which Coinbase and Cloudflare co-founded the x402 Foundation as a neutral governance body in September 2025, revives a long-dormant HTTP status code numbered 402, originally labeled "Payment Required." The protocol lets servers demand instant stablecoin micropayments from clients before granting resource access. It requires no account, no KYC, and no API keys. Over the past 30 days, x402 has processed roughly 75.4 million transactions worth $24.2 million, with approximately 94,000 active buyers and 22,000 active sellers on the network (per x402.org at time of publication). DC Builder, a research engineer at the World Foundation, pointed to the scale risk that AgentKit is designed to contain: "If you delegate an agent the ability to book tickets, you can spawn like 100,000 tickets" even with sufficient funds available. The AgentKit launch aligns with a broader push from Coinbase into agentic infrastructure: the company introduced an AI agent wallet on its Base network in February 2026, reflecting the two organizations' converging strategies around autonomous commerce.

World reports approximately 18 million verified individuals across more than 160 countries, with its dedicated Ethereum layer-2 network, World Chain (built on the OP Stack), recording more than 33.5 million users. The WLD token traded near $0.39 on March 17, giving it a circulating market cap of approximately $1.14 billion. WLD rose roughly 10% the prior day on momentum from Nvidia's GTC conference. Some background on the token is useful here: World was originally launched as Worldcoin, a project that rewarded users with WLD tokens for submitting to iris scans before rebranding toward a broader proof-of-personhood identity platform. Developers should note that holding WLD is not a requirement for using AgentKit or World ID; the token is a separate rewards layer.

For developers building outside North America and Western Europe, the picture is more complicated. The x402 micropayment layer has clear relevance in markets where credit cards and subscription billing lock out large populations. The "no account, no KYC" design addresses a real infrastructure gap across South Asia and sub-Saharan Africa. However, World's biometric collection model has run into significant regulatory opposition in several of those same markets. India is actively investigating the company for privacy violations tied to its iris scanning practices. Indonesia issued a temporary suspension of World ID operations in May 2025 over data protection licensing questions, with World voluntarily pausing services pending clarification. The Philippines issued a cease-and-desist order that World is currently appealing; the company has expressed alarm at the ban after completing a year of compliance work with government agencies. Kenya ordered the deletion of all biometric data collected from more than 300,000 citizens. Colombia issued an immediate and permanent shutdown order citing data protection failures. Any developer adopting AgentKit as a core trust layer for a product serving these markets will need to account for jurisdictional uncertainty around the underlying biometric infrastructure.

Orb device availability adds a second constraint. World currently operates roughly 1,600 active Orbs globally; the company had set a target of 7,500 deployed Orbs by the end of 2025, and developers should consult World's current rollout figures when assessing coverage projections. Users who cannot reach an Orb cannot obtain a World ID, which limits AgentKit's usefulness as a universal onboarding layer for global applications. The "Know Your Agent" (KYA) and "Know Your Human" (KYH) frameworks being discussed by industry groups, modeled on traditional Know Your Customer compliance, remain emerging standards, and no confirmed regulatory mandates for their adoption have been established. AgentKit is currently in beta, and World is accepting developer feedback during the beta period.
