- What happened
- LangChain released Restock, a sample agent that purchases office supplies through Slack using Stripe's Link wallet and the Machine Payments Protocol.
- Why it matters
- Engineers building payment-capable agents need patterns for handling credentials safely, enforcing spending limits, and integrating real transactions into agent workflows.
- Watch out
- Restock is a sample supporting only US delivery and USD; the Machine Payments Protocol requires merchant API support, limiting where agents can actually buy.
