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

说明与用途

构建了一个无状态的 FastAPI 摘要服务，验证 x402 微支付并在 Base 上自动赚取 USDC。

问题

Developers want to monetize a stateless AI service via micropayments without complex invoicing.

结果

A fully functional, stateless AI summarization service that earns USDC automatically, with minimal code and no manual invoicing.

工作流

• 1. Set up FastAPI app with x402 header validation.
• 2. Load AI summarization model at startup.
• 3. Verify x402 payload, signature, and nonce for each request.
• 4. Run summarization and return result if payment verified.
• 5. Use a lightweight script or The Graph to poll USDC contract for earnings.
• 6. Optionally schedule background tasks for model warm‑up or cache priming.

证据

Run a stateless HTTP endpoint that performs a useful AI task and charge callers a tiny USDC fee via the x402 protocol; the agent simply watches its balance grow.
