Card Members are now protected from financial losses resulting from AI agent mistakes. This protection is provided through Amex Agent Purchase Protection, an industry-first commitment to cover charges related to AI agent error.
To qualify for this protection, a Card Member must authorize an AI agent to make a purchase and that agent must send American Express the customer’s authenticated purchase intent. This mechanism is enabled by the Agentic Commerce Experiences (ACE) Developer Kit, a framework providing technical specifications for AI agents to transact on the the Amex network.
The Kit includes Agent Registration to verify AI agents and Intent Intelligence to ensure purchase intent is accurately captured for authentication, authorization, and disputes. American Express leverages its closed-loop network to authenticate both the human and the AI agent’s intent. This infrastructure allows the company to protect eligible customers from charges related to AI agent error.
