HumanLayer

HumanLayer is an API and SDK that enables tool-calling AI Agents to contact humans for help, feedback, and approvals.

HumanLayer offers a human-in-the-loop infrastructure for AI agents, enabling them to seek human assistance, feedback, and approvals seamlessly. Through its API and SDK, developers can integrate human oversight into AI workflows, ensuring critical functions like approvals or complex tasks are managed by humans when necessary. The platform supports asynchronous workflows, pre-filled response prompts, and routing to specific individuals or teams, making it ideal for agentic AI systems. With features like learning-based auto-approvals, escalations, and timeouts, HumanLayer enhances reliability while maintaining human control. It’s designed for developers using Python, TypeScript, or custom clients, offering a quick setup and free access for tinkerers. By inverting the flow of control, HumanLayer empowers AI agents to operate more effectively with human guidance.
