Loopuman

Human-in-the-loop for AI agents. Give any AI agent instant access to real human workers for verification, judgment, subjective evaluation, and real-world actions.

When an AI agent encounters a task that needs human intelligence — content moderation, fact-checking, image labeling, real-world observation — it calls Loopuman. A human worker completes the task in seconds, gets paid instantly via cryptocurrency, and the agent receives the result.

Features

• Synchronous human responses — Ask a question, get a human answer inline (typical response: 30-120 seconds)
• Async task posting — Post tasks and get webhook callbacks on completion
• Bulk operations — Submit thousands of tasks via batch API
• Instant payments — Workers paid via Celo blockchain (USDC/USDT/cUSD)
• Global workforce — Workers on Telegram and WhatsApp worldwide
• Pre-funded accounts — Deposit via crypto or Stripe, agent spends balance
