LangChain Cookbook Enables Agents to Pay for Tools

LangChain announced a new cookbook with Nevermined AI. It allows agents to make payments for services mid-task without human input. Users delegate a card and set spending limits in advance. Agents can then buy credits, replenish balances on their own, and pay for the tools or access they need. Every transaction stays traceable in LangSmith. The approach targets blocks that stop long-running agents when they lack API access, tokens, or other resources.
