American Express Is Building the Trust Layer for Agentic Commerce

American Express announced on April 14 the launch of its Agentic Commerce Experiences (ACE) Developer Kit, a framework that gives developers the technical specifications to bring American Express-issued cards and membership value into AI-powered transactions across its network.

The announcement positions the company as one of the first major payment networks to build dedicated infrastructure for agentic commerce, a category in which AI agents execute purchases, bookings, and other transactions on behalf of users without requiring manual confirmation at each step, according to the press release.

The ACE Developer Kit provides select developers with access to five integrated services. Agent Registration verifies AI agents so only trusted agents are authorised to transact on the American Express network.

Account Enablement allows card members to register their cards for agentic transactions and enable personalised membership experiences.
