AP2 Protocol

What is AP2?

AP2 (Agentic Payments Protocol) is Google’s framework for enabling AI agents to participate in commerce autonomously. It connects AI agents to Google’s vast merchant ecosystem — Google Shopping, Google Pay, and Merchant Center — allowing agents to discover products, compare prices, and complete purchases on behalf of users.

How It Works

1. Agent receives a purchase intent — user or system triggers a buying task
2. Agent discovers merchants — queries Google’s merchant catalog via AP2
3. Agent compares options — evaluates price, availability, shipping, and reviews
4. Agent initiates checkout — creates a purchase request through AP2
5. Google Pay processes payment — handles authentication and settlement
6. Agent confirms order — receives order confirmation and tracking details

Key Technical Details

• Merchant Discovery: Access to Google Shopping’s merchant catalog
• Payment Processing: Google Pay infrastructure for secure settlement
• Agent Authentication: OAuth-based agent identity verification
• User Authorization: Delegated spending permissions with limits
• Integration Points: Google Shopping, Google Wallet, Merchant Center

Use Cases

• Automated Shopping — AI agents find and purchase the best deals
• Price Comparison — real-time comparison across thousands of merchants
• Subscription Management — agents auto-renew and optimize subscriptions
• Enterprise Procurement — autonomous purchasing within approved budgets
• Inventory Restocking — AI-driven supply chain automation

Why It Matters

AP2 brings Google’s massive commerce infrastructure to AI agents. Unlike crypto-native protocols, AP2 works with traditional payment rails (credit cards, bank transfers via Google Pay), making it immediately accessible to enterprises already in the Google ecosystem.
