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

说明与用途

构建了一个自主 AI 代理，使用 x402 规范在 Base 上接受 USDC 支付，并在支付确认后自动返回结果，实现 24/7 无需人工干预的运行。

问题

Expose an AI model or data‑processing function as a paid on‑chain service that can operate 24/7 without manual intervention.

结果

The prototype runs continuously, automatically billing clients in USDC on Base and releasing AI results only after payment confirmation, eliminating manual intervention.

工作流

• 1. Client sends HTTP request to API Gateway
• 2. API Gateway validates request, creates x402 invoice, and enqueues job ID in Redis queue
• 3. Payment Verifier watches Base USDC contract for matching paymentRequest and marks job as paid
• 4. Worker Pool pulls job from queue, runs AI inference or computation
• 5. Worker stores result in temporary object store (IPFS/S3)
• 6. Worker returns result to client after payment confirmation

证据

The x402 payment spec (ERC‑4337‑compatible) lets a service generate an invoice, receive USDC on Base, and automatically verify that payment succeeded before releasing the result.

All components are deliberately stateless except the queue and the wallet, which makes horizontal scaling straightforward.
