Summary
NPCI's Unified Agent Protocol (UAP) is designed as a verification layer on top of existing UPI infrastructure, creating a common interoperable framework for registering, verifying, and authorizing AI agents. This contrasts with Coinbase's x402 protocol (enabling fully autonomous AI-driven commerce without human-in-the-loop), Pine Labs' P3P protocol (open-sourced agentic OAuth framework), and Visa's and OpenAI's proprietary initiatives. UAP preserves UPI's interoperability while adding a trust layer for machine-initiated transactions. The protocol would verify whether an AI agent is authorized to act for a user, define transaction permissions, and establish accountability. RBI approval is required before implementation. Default limits and separate agent PINs are proposed as safeguards.
Key Points
- NPCI UAP: verification layer on existing UPI, interoperable, agent registration/verification
- Coinbase x402: fully autonomous, no human-in-the-loop, permissionless
- Pine Labs P3P: open-sourced agentic OAuth framework (GrantEx on GitHub)
- Visa/OpenAI: proprietary agentic payment protocols under development
- UAP safeguards proposed: separate agent PIN, transaction limits (amount, count, period)
- RBI approval required before implementation
- First use cases: low-value repetitive purchases (groceries, daily essentials)
- UPI June 2026: 22.71B transactions, 28.92 trillion rupees
- MediaNama recommends delegated handles (agent@user@bank) and default limits
