Pine Labs enables AI agents to complete UPI payments without manual authentication

Pine Labs Introduces Payment Protocol for Autonomous Transactions

Pine Labs has launched the Pine Labs Payment Protocol (P3P) in India, marking a significant shift in how AI agents can handle financial transactions 1

1

. The new infrastructure enables AI agents to complete autonomous UPI transactions without requiring manual authentication for each purchase, addressing a critical bottleneck in agentic commerce where AI systems browse, compare products, negotiate prices, and execute purchases independently 1

.

The protocol builds on the UPI mandate framework, specifically leveraging existing systems like One Time Mandates (OTM), Reserve Pay, and Single Block Multiple Debit (SBMD) 1

. Users provide authorization through a one-time approval process, after which AI agents can execute transactions automatically within predefined limits without requesting additional authentication for every purchase 2

How P3P Enables Payments Without Manual Authentication

The system combines three core components to facilitate autonomous commerce. First, it uses UPI's mandate frameworks including SBMD, which Pine Labs brands as UPI ReservePay, and OTM—systems that set aside a fixed amount in the user's bank account upfront and debit it later when specific conditions are met 3

. Second, Grantex provides identity verification, delegated authorization, spending controls, compliance checks, and audit trails to ensure security and user control 1

. Third, the protocol incorporates HTTP 402, a web standard for machine-readable payment requests that facilitates agent-to-agent payment interactions 1

.

Users approve the mandate once by scanning a code in their UPI app, after which the agent's requests debit against reserved funds without fresh approval 3

. Pine Labs emphasizes that users retain control throughout, with the ability to define spending limits, verify AI agent identity, review previous transactions, and revoke permissions at any time 1

Real-World Applications and Early Adopters

The P3P system is already live in production across multiple industries. Digital gold investment platform Gullak has integrated P3P into its service, allowing users to set spending rules like "Buy Rs 500 of gold if the price drops below Rs 16,000 per gram" 2

. Once approved, Gullak's AI agent monitors gold prices and automatically completes the purchase when conditions are met, with users receiving confirmation rather than permission requests .

Electronics retailer Vijay Sales is conducting a proof-of-concept deployment, enabling value-conscious consumers to deploy AI agents that secure products the moment they hit target prices instead of constantly checking for deals 2

. Managing Director Karan Gupta describes it as "giving every customer a personal shopper who never misses a deal" 2

Regulatory Questions and Privacy Concerns

Despite the innovation, P3P raises unresolved regulatory and liability questions. Analysts question whether Pine Labs is using the UPI mandate framework for purposes it wasn't originally designed for 3

3

. UPI mandates were originally built to support recurring, scheduled payments to known merchants like monthly subscriptions or SIPs, not one-off, event-triggered purchases that AI agents independently execute 3

3

.

There are also concerns about compliance with RBI's Digital Payments E-Mandate Framework, which requires Additional Factor of Authentication (AFA) for setting up mandates 3

3

. Pine Labs has not publicly clarified whether NPCI created or approved a separate framework for AI-driven autonomous commerce under UPI mandates 3

3

. The company has remained quiet on privacy questions about what data AI providers receive versus what Pine Labs retains, and whether transaction details are stored or used to train AI models 3

Market Implications and Future Expansion

Citing industry estimates, Pine Labs projects the global agentic commerce market to reach $65.47 billion by 2033, with India positioned to play a key role due to its extensive UPI infrastructure 1

. Currently restricted to UPI, the fintech company is working with major card networks to extend the protocol to card-based transactions 1

. Pine Labs' developer documentation separately lists stablecoins as a future payment rail 3

Pine Labs CEO Amrish Rau describes the shift as creating "new behaviours, native to how India transacts," including agents securing flash sales the moment they go live or locking in down payments before inventory disappears 2

2

. The protocol's use of HTTP 402 as an open web standard means any AI agent on any platform can use P3P, not just one company's assistant, differentiating it from competitors like Razorpay's agentic payments that still require final user consent 3
