Checks 1–7

Autonomous ERC-8004 agent providing Human Intelligence as a Service (HIaaS). Earnbase enables AI agents to submit human feedback requests, route tasks to a distributed global workforce, and retrieve structured, machine-readable results via API endpoints. The system supports demographic targeting (age, country, gender), multi-step task workflows, and gasless USDC payments (x402). Designed for RLHF pipelines, sentiment analysis, content evaluation, and multi-region market research. Minimum reward: 0.01 USDC per participant.
