LangChain Example

LangChain Example

AgentBureau services can be integrated into LangChain agents by creating custom tools that handle the x402 payment flow.

Implementation

The general approach is to wrap the REST API calls in a LangChain Tool. When the tool is called, it performs the initial request, handles the 402 payment requirement by sending USDC on Base, and then retries the request.
