Inside AMEX’s agentic commerce stack: How intent contracts and single-use tokens enforce AI transactions

American Express launched an Agentic Commerce Experiences kit for AI-led shopping and payments.

It uses AmEx’s issuer-network to verify transactions with intent matching and single-use payment credentials.

The company is also aligning with broader efforts like Google’s AP2, but some validation details remain unclear.

That opacity raises questions about transparency, auditability, and fraud risk even as AmEx aims to make agentic payments safer.
