FAQ

What is pay_for_resource?

It lets the agent autonomously pay for an HTTP 402 (x402) gated API in USDC, within a budget you configure with set_agent_budget. The agent never holds a master key.

Does it support LCEL and LangGraph?

Yes — the tools are standard LangChain BaseTool instances and work anywhere LangChain tools do, including LangGraph nodes.
