Pine Labs, India’s leading merchant commerce platform, announces the Pine Labs Payment Protocol (P3P) — and for the first time in India, an AI agent can complete a UPI payment without human authentication. Pine Labs is India’s first payment company to close this gap. Live in production today.
The Problem
UPI processes over 23 billion transactions a month (NPCI, May 2026) — the most widely adopted real-time payment network in the world. But it was built for humans. Every transaction assumed a person approving at the other end.
In agentic commerce — where AI acts on a user’s behalf — there is no person at that moment. The agent reaches checkout. The authentication screen appears. The transaction fails. No payment company in India had solved this.
How P3P Works
The Pine Labs Payment Protocol (P3P) extends UPI’s existing mandate framework — already proven through UPI One Time Mandates and Reserve Pay — into payments triggered by AI agents. The consumer authorises once, upfront. After that, the agent browses, selects, negotiates, and pays. No human authentication. No interruption. No friction.
P3P provides the payment and settlement rails for autonomous commerce. Grantex provides verifiable identity, delegated authorization, spend controls, and auditability. HTTP 402 — an open web standard for machine-readable payment requests — provides a standardised protocol for discovering and requesting payment. Together, they enable trusted, secure, and auditable agent-to-agent transactions on behalf of merchants without requiring human intervention.
Grantex allows the consumer to be in absolute control — checking agent identity, enforcing pre-approved spending limits, and creating a full audit trail for every payment. The consumer can revoke or update the mandate at any time. Compliance is not an afterthought — it is built into the protocol layer. No guardrails, no payment.
Real Commerce, Live Today
Gullak, India’s leading digital gold savings platform, is live on P3P today. A Gullak user sets a simple rule — “Buy ₹500 of gold if the price drops below ₹16,000 per gram” — and approves a UPI mandate once. Gullak’s AI agent follows to do the rest. The consumer gets a confirmation, not a request for permission.
“Gold is deeply cultural, but timing the market takes attention most people simply don’t have,” says Mr. Manthan Shah, Co-founder, Gullak. “With P3P, we are moving from manual savings to autonomous wealth creation. Pine Labs has built the infrastructure to make this possible.”
Deployments are underway across retail, fintech, travel, and beyond. Further partner announcements will follow.
Vijay Sales — one of India’s most trusted electronics retail chains with over 150 stores nationwide — is in active proof of concept with P3P.
“Electronics buyers in India are highly value-conscious — they are always waiting for the right deal or the right price drop,” says Mr. Karan Gupta, Managing Director, Vijay Sales. “P3P fundamentally alters this dynamic. Instead of a customer constantly checking back for discounts on a smartphone or refrigerator, they can now deploy an AI agent to secure that product the moment it hits their target price. It’s like giving every customer a personal shopper who never misses a deal.”
What It Means for India
India does not follow the global agentic commerce wave. It leads it. The global agentic commerce market is projected to reach $65.47 billion by 2033, growing at a CAGR of 35.7% (Grand View Research, 2025). India — with a rising UPI user base and P3P now live — is positioned at the centre of that growth.
UPI’s Single Block Multiple Debit (SBMD) and One Time Mandate (OTM) frameworks are built for exactly this — letting consumers “block now, debit on event” with near-instant settlement. By anchoring P3P onto this architecture, Pine Labs keeps the consumer in absolute control — authorising a single mandate upfront, with Grantex ensuring the AI stays within its bounds.
“We have always built by asking what existing infrastructure already makes possible — then building the layer that was missing. In India, UPI’s mandate framework was already architected for agentic commerce. P3P is that layer. An agent securing a flash sale the moment it goes live. A down payment locked in before inventory disappears. A savings trigger at the right price. These are new behaviours, native to how India transacts. Pine Labs is building the commerce infrastructure for that world. Not catching up to anyone. Building ahead,” said Mr. Amrish Rau, CEO, Pine Labs.
Built for UPI. Expanding to Every Rail. P3P is live on UPI today. Pine Labs is working with major card networks to extend P3P’s mandate-based authorization to card transactions — making the Pine Labs Payment Protocol the payment foundation for all agentic commerce in India.
