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

Описание и применение

Создайте автономного AI‑агента, который зарабатывает USDC, используя HTTP 402 и Base L2, чтобы автоматически принимать и обрабатывать платные запросы.

Задача

Developers want a language‑model‑driven service that can earn micro‑payments automatically without manual top‑ups.

Результат

The agent earns USDC per response, operates unattended, and eliminates ad or subscription models.

Рабочий процесс

• 1. Set up a Node.js Express gateway that checks the X402‑Payment header.
• 2. Validate the USDC transfer on Base using ethers.js (check tx hash, recipient, amount).
• 3. If payment is valid, forward the request to the Flask worker.
• 4. The worker calls an LLM, processes the request, and returns JSON.
• 5. The gateway returns the response to the client.
• 6. The system runs unattended; the gateway keeps the balance to cover gas fees.

Доказательства

Pair it with a stablecoin like USDC on a low‑cost L2 (Base) and you get sub‑cent transaction fees that make micro‑services viable.
