UCP Razorpay UPI Payment Handlers: India's Payment Rails Meet Agentic Commerce

What's Being Proposed

On March 27, 2026, Razorpay engineers opened four related PRs that collectively add India's UPI payment ecosystem to UCP:

• PR #316: Hosted checkout payment handler for Razorpay Magic Checkout
• PR #315: UPI Intent payment handler (com.razorpay.upi)
• PR #314: UPI Circle (delegated UPI) payment handler for agentic commerce
• PR #313: UPI Intent payment instrument and credential schemas

The most interesting of these is UPI Circle — Razorpay's delegated payment feature where users pre-authorize trusted contacts (or agents) to make UPI payments on their behalf up to a specified limit. This maps naturally to agentic commerce scenarios.

Why UPI Matters for Agentic Commerce

India's Unified Payments Interface (UPI) is the world's largest real-time payment system by transaction volume. Unlike card-based systems:

• Real-time settlement: Transactions complete in seconds, not days
• Zero/low merchant fees: Dramatically lower than card networks
• Intent-based flows: Users confirm payments via their banking app
• QR and deep-link native: No card numbers to transmit

For AI agents, UPI's intent model presents both opportunities and challenges. An agent can't tap a phone to approve a payment — but UPI Circle's delegation model solves this elegantly.

UPI Circle: Delegation for Agents

The UPI Circle PR is particularly significant. The flow:

1. User setup: Customer creates a UPI Circle delegation in their banking app, authorizing a merchant/agent with a spending limit
2. Agent discovery: UCP's capability discovery reveals com.razorpay.upi.circle as available
3. Agent-initiated payment: The AI agent can initiate payments within the delegated limit without per-transaction user approval
4. Real-time completion: UPI settles immediately; agent receives confirmation

This is agentic commerce done right: explicit user consent and limits, machine-readable capabilities, and real-time settlement.

Technical Architecture

The PRs add several schema components:

// UPI Intent Instrument (PR #313)
{
  "type": "com.razorpay.upi.intent",
  "vpa": "user@upi",  // Virtual Payment Address
  "app_preference": ["gpay", "phonepe", "paytm"]
}

// UPI Circle Credential
{
  "type": "com.razorpay.upi.circle",
  "delegation_id": "del_xxxxx",
  "limit_remaining": 5000,
  "currency": "INR"
}

The hosted checkout handler (PR #316) provides a fallback for cases where delegated payment isn't available — redirecting to Razorpay's Magic Checkout for full payment method selection.

Market Context

This contribution is significant for several reasons:

• First major Indian payment processor: Razorpay processes a substantial portion of India's digital payments. Their UCP participation validates the protocol's global ambitions.
• Real-time payment focus: UCP has been card-centric so far; UPI represents a fundamentally different payment paradigm.
• Delegation as a pattern: UPI Circle's delegation model could inspire similar patterns for other payment methods (pre-authorized ACH, delegated wallets).

Implications for AI Commerce

For AI agent developers building commerce experiences:

• India becomes accessible: A market of 1.4B people with 500M+ smartphone users can now transact via UCP-compliant agents
• Delegation patterns: UPI Circle provides a template for agent-authorized payments elsewhere
• Real-time feedback: UPI's instant settlement means agents know immediately if payments succeeded

For businesses implementing UCP, supporting these handlers means access to India's digital-native consumers who increasingly expect AI-assisted shopping experiences.

Next Steps

These PRs are currently open and under review. Key questions the community is evaluating:

• How should delegation limits be communicated to agents at capability discovery time?
• Should UPI-specific error codes map to UCP's semantic status system?
• How do multi-party UPI flows (like split payments) fit the protocol?

Expect iteration on the schemas before merge, but the direction is clear: UCP is becoming genuinely global.
