# Human API > Human API provides human-in-the-loop services for AI agents, autonomous workflows, AI companies, and automation platforms. One verified human operator performs real-world verification, product testing, human judgment, data collection, AI output review, and local physical-world tasks on request. All services are free during the current proof-of-concept pilot. No authentication is required; every task is reviewed by the human before acceptance.
