Stripe Says Agent Payments Need Deterministic Controls, Not Browser Automation

Stripe’s Steve Kaliski argues that autonomous agents can use probabilistic reasoning to discover products, services and tools, but payments should move through deterministic infrastructure. In his talk, he presents Stripe’s approach to agent commerce: scoped payment credentials, HTTP-based paid tool calls and structured checkout APIs designed to prevent agents from paying the wrong merchant, buying the wrong item, authorizing the wrong amount or exposing the wrong credential.
