How I Built an Autonomous AI Agent That Earns USDC While I Sleep

Описание и применение

Минимальный прототип автономного ИИ‑агента, который принимает микроплатежи через x402, выполняет инференс и автоматически переводит заработанные USDC в резервный кошелёк, устраняя необходимость ручного пополнения.

Задача

Developers need a self‑funding AI agent that can pay for its own compute and data without manual wallet funding.

Результат

The prototype demonstrates a self‑funding AI agent that can accept micropayments via x402, perform inference, and automatically sweep earnings to a reserve wallet, eliminating manual funding bottlenecks.

Рабочий процесс

• Expose a FastAPI endpoint that checks for a valid X‑Payment header (x402).
• Verify the signed payment header against expected price and token.
• Enqueue a job to a Redis queue if payment is valid.
• Worker process pulls job, runs lightweight inference, stores result.
• USDC Sweeper cron task transfers any balance above a dust threshold to a reserve address.
• Log the transaction for audit.
• Repeat the cycle for each incoming payment.

Доказательства

The prototype described here does three things repeatedly: Expose a paid HTTP endpoint, Perform a small unit of work, Sweep the earned USDC to a reserve wallet

Источник

The agent needs an Ethereum-compatible wallet (Base is an EVM L2) to hold USDC and to sign the x402 payment verification message.
