AP2 (Agent Payments Protocol) is the open, verifiable standard securing AI-driven commerce transactions with cryptographically signed mandates.

AP2 (Agent Payments Protocol) establishes the secure, open framework for AI agents to transact on a user's behalf. Developed by Google and industry leaders, this non-proprietary protocol extends Agent2Agent (A2A) and Model Context Protocol (MCP) standards. Its core innovation is the use of cryptographically signed mandates: tamper-proof digital contracts that provide verifiable proof of user intent and authorization for every payment. This system ensures clear accountability, prevents ecosystem fragmentation, and supports all payment types, from cards to stablecoins, building essential trust in autonomous commerce.
