Stripe Trust Flow — Fiat Authorization
The trust layer behind agent-mediated payments at Stripe: the agent submits a shared payment token, the risk engine approves it and fiat clears through the banking rails.
Agent-Mediated Fiat Payment Workflow
Stripe Agent Toolkit flow: the consumer approves an agent spend, the agent requests a scoped token, passes it to the merchant and the order completes in fiat.
