Introduction
Agent Payments Protocol (AP2) is Google's new solution for secure AI-driven payments, already supported by over 60 leading companies. This protocol aims to transform how consumers and businesses interact with artificial intelligence in online transactions.
Context
As e-commerce evolves, AI agents are taking center stage: they can order products for users and help merchants connect with buyers. However, payment data security remains a major concern.
Quick Definition
Agent Payments Protocol is an open standard ensuring secure AI transactions between users, agents, and merchants.
The Challenge
The main challenge is trust: AI agents access payment data and can act autonomously. Without a secure system, the risk of fraud and unauthorized actions is high.
Solution / Approach
AP2 addresses these issues through Mandates, cryptographically signed digital contracts certifying user intent. There are two types: Intent Mandate (request to search or buy) and Cart Mandate (final purchase authorization). These tools ensure agents act only within user-defined rules.
Direct Snippet
AP2 uses digital Mandates to authorize and track every AI payment, reducing risks.
How AP2 Works
The protocol supports various payment methods, including credit cards, stablecoins, and instant bank transfers. For real-time purchases, users sign the authorization; for delegated tasks, rules are set upfront and agents act autonomously within those limits.
Impact and Adoption
Over 60 companies, including Mastercard, PayPal, Coinbase, and Salesforce, have adopted AP2. Google provides technical specifications and reference implementations on GitHub, encouraging rapid adoption.
Conclusion
Agent Payments Protocol marks a major step toward secure and transparent AI payments, with the potential to reshape digital commerce. Collaboration between tech and financial firms strengthens trust in the system.
