To add a human-in-the-loop mechanism to your FastAPI-hosted agent, you can consider implementing checkpoints where human approval is required before proceeding with certain actions. LangChain provides guidance on this by suggesting the use of HumanApprovalCallbackHandler and AsyncHumanApprovalCallbackHandler for manually validating values. These handlers can prompt for human approval of inputs, and if the input is not approved, a HumanRejectedException is raised, effectively integrating human intervention into the workflow ^[1].

Additionally, you can incorporate error handling and logging mechanisms to trigger human intervention when necessary. For example, logging inputs and outputs, especially when exceptions occur, can allow humans to review and correct errors, which can then be used to improve the model's performance ^[2][3].

These approaches can be adapted to your specific use case within the FastAPI application by integrating them into the existing endpoints or creating new ones that facilitate human oversight.
