Amex wants a proof of intent before an AI agent can buy anything
American Express published an Intent Intelligence Framework on 13 October 2026 that asks a cardholder to approve an agent's shopping instructions before a payment credential is issued. The control sits in the network and the credential, unlike the agent-side budget cap in our earlier piece on Google's enterprise agent. No live deployment was found, and the Create Intent API's public status is unconfirmed.
