AI agents comparing prices, booking tables, and making payments on your behalf — McKinsey projects this market could reach $3 to $5 trillion by 2030. But there's a problem: nobody can verify whether there's a real person behind these agents or not.
What Is This?
World (formerly Worldcoin), the identity project co-founded by Sam Altman, just launched AgentKit. In short, it's a developer toolkit that gives AI agents cryptographic proof there's a real person behind them.
Here's how it works: you scan your iris with the Orb device to create a unique World ID. Link that ID to your AI agent, and when the agent accesses a website, it can prove "I'm an agent sent by a verified, unique human". It uses zero-knowledge proofs, so no personal information is ever exposed.
AgentKit integrates with the x402 protocol developed by Coinbase and Cloudflare — a layer that enables AI agents to make micropayments. AgentKit adds "proof of human" on top. As Erik Reppel, head of engineering at Coinbase Developer Platform, put it: "Payments are the 'how' of agentic commerce, but identity is the 'who'".
Key Concept
KYC (Know Your Customer) → KYA (Know Your Agent) → Know Your Human. Identity verification for agentic commerce is evolving through three stages.
The World network currently has approximately 18 million verified users across 160+ countries. Bain estimates AI agents could account for up to 25% of all U.S. e-commerce by 2030.
What Changes?
Until now, websites just blocked all automated traffic — legitimate agents and malicious bots alike. AgentKit changes the rules of the game.
| Current Approach | With AgentKit | |
|---|---|---|
| Bot handling | Block all automated traffic | Allow human-backed agents only |
| Fraud prevention | Micropayments as rate limiter | Limit agents per unique human |
| Reservations | CAPTCHA, phone verification | 1 unique human = 1 booking guaranteed |
| Privacy | Payment trail tracks everything | Zero-knowledge proofs preserve anonymity |
| Free trials | Unlimited email account abuse | N trials per unique human |
For example, if a popular restaurant platform adopts AgentKit, AI agents can still make reservations — but one person running 100 agents to hoard seats becomes impossible. Same goes for concert ticket scalpers. The bottom line: this isn't about blocking agents, it's infrastructure for distinguishing good agents from bad ones.
According to PYMNTS research, 56.3% of global companies face bot- or agent-related threats, losing an average of 3.1% of annual revenue to digital identity system gaps — $94.9 billion in aggregate.
Getting Started
- Create a World ID
Find your nearest Orb location at world.org and complete the iris scan. - Check the AgentKit docs
Access the developer preview atdocs.world.org/agents/agent-kit. Currently in beta. - Delegate World ID to your agent
After verification, register your agent to carry "proof of human" on x402-enabled sites. - Integrate into your platform (for businesses)
If you already use x402, you can add AgentKit as an additional layer — require micropayments and proof of human together, or choose one. - Set limits
Configure per-human caps: number of agents, daily transactions, free trial uses, etc.
Note
AgentKit is currently in beta with Orb-based biometric verification required. NFC passport/ID verification is planned but not yet available.
