Vendor profile, card network
American Express
In short
American Express packages its agent offer as the ACE developer kit, covering agent registration, account enablement, intent checks, tokenised credentials and cart context. Credentials go only to verified agents, and a purchase proceeds only after the Card Member approves the intent. Amex has not yet released its roster of registered agents, and the protection terms are still to come.
