“Agentic payment systems — anchored to verifiable mandates and agent grounding.”
AI agents are beginning to transact autonomously and the industry is converging on mandate-based protocols (Google AP2, Mastercard Agent Pay, Visa Trusted Agent, Stripe ACP). Teams built a safe agent-checkout prototype using signed mandates and a grounding knowledge graph.
The problem AI agents are beginning to transact autonomously, and the industry is converging on mandate-based protocols (Google AP2, Mastercard Agent Pay, Visa Trusted Agent, Stripe ACP). The open problems are trust and grounding: proving an agent acts within real user authority, and preventing hallucinated or out-of-scope purchases. What teams built A safe agent-checkout prototype that represents user intent, cart, and payment as signed mandates, and uses a knowledge graph of catalogs, entitlements, policies, and merchant trust to ground the agent so it only buys what is authorized and in scope. Partner ROI A hands-on view of agentic-commerce readiness, an interoperability test across emerging protocols, and a grounding pattern that reduces agent risk. Skills proven Agent frameworks, verifiable credentials, protocol integration, knowledge-graph grounding, payments and risk fluency.
