Riley Brown gives a Grok-based agent its own inbox, connects incoming mail to a webhook and configures a routine that reads purchase requests. This lets a normal email become a structured trigger for an agent workflow.
Brown then connects Stripe Link so the agent can request a virtual payment card for a specific transaction. After human approval, the agent searches Amazon, chooses a product and completes the checkout while reporting its progress.
The demonstration shows how email, browser control and narrowly authorized payments can turn an assistant into an operational agent. Brown also highlights the need for spending limits, explicit approval and tightly scoped credentials before such workflows are trusted with real purchases.
