American Express was building for the next era of commerce. As AI agents reshape how Card Members make everyday transactions, the company is bringing its longstanding tradition of trust, security, and service into AI-powered commerce. American Express is introducing an agentic commerce developer kit and announcing Amex Agent Purchase Protection, an industry-first commitment to extend its backing to Card Member purchases made by registered AI agents across its network.
The Amex Agentic Commerce Experiences (ACE) Developer Kit is a framework that provides technical specifications to bring American Express-issued Cards and Membership value into AI-powered interactions with trust and control. Designed for flexibility and interoperability with existing and emerging protocols, the ACE Developer Kit will enable intent-driven transactions with end-to-end visibility across the commerce lifecycle through Amex?s closed-loop network. The Kit will provide select developers with access to integrated services including: Agent Registration to verify AI agents so only trusted agents are authorized to transact on the Amex network; Account Enablement to allow Card Members to register their Cards for agentic transactions and enable personalized Membership experiences; Intent Intelligence to ensure Card Member purchase intent is accurately captured to support authentication, authorization, and disputes; Payment Credentials to enable verified AI agents to complete payments on behalf of a Card Member leveraging tokenized credentials; Cart Context to support the sharing of cart details, before or after a transaction, to enhance validation, authorizations, and dispute investigations.
American Express? approach to agentic commerce is rooted in its long history of backing customers in every transaction. Building on this foundation, American Express is announcing an industry-first commitment to offer customers protection for registered agent purchases through Amex Agent Purchase Protection.
In the future, if a Card Member authorizes an AI agent to make a purchase and that agent sends American Express the customer?s authenticated purchase intent, American Express will protect eligible customers from charges related to AI agent error. American Express? closed-loop network ?
operating as issuer, network, and acquirer ? provides direct relationships with millions of Card Members and Merchants, as well as an end-to-end view of every transaction. It positions the company well to holistically manage the challenges agentic commerce presents, enabling the delivery of intent-driven authorizations, enhanced fraud protection, efficient dispute resolution, and strong security features to help protect Card Members and Merchants.
With the Kit, American Express believes Merchants will benefit from lower disputes and chargebacks, driven by greater visibility through its closed-loop network. For Card Members, the Kit is designed to enable granular spend controls right from the Amex app and, over time, to embed Membership benefits, rewards, and offers directly into agent-powered interactions, reinforcing the differentiated value American Express delivers to its customers. American Express is already enabling agentic commerce, including completing AI-assisted transactions with AI platform partners, while collaborating with AI companies and industry associations to help define standards and protocols for a secure, seamless agentic payments ecosystem.
As the company advances its work in agentic commerce, it is focused on three priorities. First, embedding its payment capabilities into emerging AI ecosystems, including through the ACE Developer Kit, to help enable trusted, seamless agent-driven transactions. Second, making its Membership assets discoverable and actionable across AI platforms, enabling capabilities such as Resy restaurant booking, and, over time, Amex Offers and American Express Travel.
Third, building proprietary AI-powered experiences across its owned platforms to help Card Members access relevant Membership value within AI-driven journeys.
