Amex ACE lets AI agents shop and pay with intent contracts and single use tokens

Validation is promised but the black box details remain hidden

American Express is rolling out its Agentic Commerce Experiences kit to let AI agents register, receive permission, follow an “intent contract,” and pay using single-use tokens within the Amex network. The system emphasizes control and proof during disputes, but its validation logic is still largely opaque, raising trust and auditability concerns outside Amex’s closed loop.
