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

说明与用途

一个在 Cloudflare Workers 上运行的自治代理，自动执行任务，生成 x402 支付请求，并将结果返回给使用 Base 上的 USDC 支付的调用者，消除了托管风险。

问题

Building an autonomous agent that can perform tasks, receive micropayments, and operate safely without custodial risk.

结果

The agent autonomously performs tasks (e.g., summarizing RSS feeds), signs payment requests, and returns results to callers who pay in USDC, eliminating custodial risk and enabling continuous revenue generation.

工作流

• Set up Cloudflare Cron Trigger to wake agent every 5‑15 minutes
• Implement Durable Object (Agent Loop) that loads state, selects a task, executes skill, builds x402 payment request
• Expose skill endpoints that return 402 Payment Required with payment payload if no valid Payment header
• Caller pays USDC via x402 relayer, receives signed payment request, and retrieves result
• Agent never holds funds, only signs payment requests, ensuring operational safety

证据

The agent never holds funds; it only signs a payment request that the caller must fulfill.

x402 protocol (HTTP 402 Payment Required) gives us a lightweight way to attach a payment request to any HTTP endpoint.
