Amex is Turning Agentic Commerce Into a Trusted Way to Pay
By W.B. King
As AI becomes more predictive, American Express recently offered a recommendation via its new Intent Intelligence framework: Capture and authenticate a customer’s purchase intent before an AI agent completes a transaction.
“American Express’s agent purchase protection and the Intent Intelligence framework it published last week are important steps for agentic commerce,” said Laurence Booth, Group CEO of Trust Payments, a fintech powering innovative customer commerce solutions across the UK and EU.
He posited that “capturing and evidencing” customer intent will be critical as AI agents become a genuine commerce channel. “Giving consumers clarity over what happens when an AI agent makes a purchasing error is a key part of building confidence in this new way of transacting.”
Evolving Capabilities
In April 2026, American Express introduced an “agentic commerce developer kit” known as Amex Agent Purchase Protection. It is billed as an industry-first commitment to extend its backing to card member purchases made by registered AI agents across its network.
“AI agents are beginning to reshape how people discover products and services, plan travel and dining, and make purchases,” noted Luke Gebb, Executive Vice President and Head of Global Innovation at American Express. “As these capabilities evolve, card members and merchants will expect the same level of trust and security that they always relied on from American Express. The ACE Developer Kit enables this in AI-powered commerce.”
The Amex ACE Developer Kit offers five Integrated services:
Developer 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 Context1: to support the sharing of cart details, before or after a transaction, to enhance validation, authorizations and dispute investigations.
Since the platform went live only on October 13, 2026, American Express confirmed the system is not currently active with partner institutions, including credit unions—those announcements are forthcoming. The company noted that it designed the offering as an open, flexible standard for card issuers, payment networks (such as EMVCo), and merchants to handle AI-driven shopping agents in the agentic era.
“As commerce becomes more agent-powered, trust becomes the defining factor. Our goal is to ensure that when an agent acts on a Card Member’s behalf, the identities of both the human and the agent are authenticated and intent is clear—so that every Amex-enabled transaction reflects the backing and seamless experience that define our brand,” said Gebb. “That’s why we’re introducing Amex Agent Purchase Protection, an industry-first commitment to protect card members from registered agent error, as we build the foundation for agentic commerce to scale with transparency, accountability and confidence.”
Developing a Common Industry Approach
Booth, who previously served as Trust Payments Chief Information Officer and Chief Data Officer, said Amex’s offerings are bringing to focus a critical AI question that must be answered: What’s the intent?
“When a shopper asks an agent to buy a specific product at a specific price, it is relatively clear what they wanted. When they ask it to find ‘the best’ option, or something that is ‘good value’, intent becomes much more subjective,” he continued. “Establishing what the customer actually authorized in those circumstances is a challenge for the whole payments ecosystem and it is encouraging to see moves towards a common industry approach.”
In the UK, he explained, existing payments and dispute frameworks largely assume that a person is making and authorizing the purchase. “As agents become a genuine commerce channel, issuers, schemes, acquirers and merchants will need a shared way to capture and evidence what the customer actually asked for.”
Under this new premise, it will become clearer where responsibility stands when something goes wrong. “This will give merchants and acquirers certainty over how agent-led transactions are handled,” he noted. “Getting this right is what will help turn agentic commerce from discovery and research into a trusted way to pay.”
