World Unveils AgentKit to Authenticate Humans Behind AI Shopping Bots

Tools for Humanity, the startup behind Sam Altman's World identity platform, has launched a beta tool called AgentKit that aims to verify real humans are authorizing purchases made by AI shopping agents — a category of software that is rapidly reshaping online commerce.

Announced on Tuesday, AgentKit is a software development kit for commercial websites that links a user's World ID — generated from an iris scan performed by the company's Orb hardware device — to AI agents acting on that user's behalf. The tool integrates with the x402 protocol, a blockchain-based open payment standard developed by Coinbase and Cloudflare that enables automated programs to transact directly online without requiring human intervention at every step. When an AI agent initiates a purchase, AgentKit communicates to the receiving website that a verified, unique human has authorized the transaction.

Tiago Sada, Tools for Humanity's chief product officer, compared the arrangement to granting "power of attorney" to a digital agent. Websites receiving agent-initiated transactions can then decide whether to trust or block specific users based on their verification status. Critically, consumers must possess a verified World ID derived from an in-person Orb iris scan to participate — a requirement that could limit adoption but strengthens the system's anti-fraud credentials.

The timing reflects growing industry urgency. Amazon, Mastercard, and Google have all moved to support agentic commerce capabilities over the past year, enabling consumers to delegate browsing and purchasing to AI programs. While the trend promises convenience, it has also raised alarm about new vectors for fraud, spam, and large-scale automated abuse. Without reliable mechanisms to distinguish legitimate agent activity from malicious bots, the entire model risks undermining consumer and merchant trust.

World is clearly positioning itself as the foundational identity layer for this emerging ecosystem. The irony remains hard to ignore: Altman co-founded World in part to address identity challenges on an AI-saturated internet, while his other company, OpenAI, has been a principal driver of that very saturation. AgentKit is currently available in beta, with Tools for Humanity soliciting developer feedback to refine the product. Any website already running the x402 protocol can enable human verification alongside or in place of micropayments, the company said, suggesting a path toward broad interoperability if adoption gains traction.
