LangChain's Restock agent shows how to build a payment-capable AI agent
Original titleAgents that can pay: building Restock with Stripe's Link and Managed Deep Agents
AISummary
LangChain built Restock, a sample office-supply agent that runs in Slack on Managed Deep Agents and pays through Stripe's Link wallet. The agent searches products, builds a cart, and pays over the Machine Payments Protocol, with the user approving the purchase in Slack and the payment in Link. The post uses a pens order at $22.18 to show the flow from request to confirmed order.
AIWhy it matters
The post walks through how an agent handles search, budget limits, Slack review, and Link approval, showing where each control sits outside the model.
