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

说明与用途

一个自主 AI 代理，使用 x402 在 Base 上即时收取 USDC 费用，利用简单的 cron 调度器执行微任务。

问题

Create a repeatable, billable micro‑task agent that receives instant USDC payment, stays inexpensive, and runs autonomously.

结果

The agent processes tasks autonomously, pays out in USDC within ~2 seconds, and keeps compute costs well below revenue per call.

工作流

• Set up a scheduler (cron or Cloudflare Workers Cron Trigger) to invoke agent.js every N minutes
• Configure a durable state store (SQLite locally, Cloudflare KV in production) to hold task metadata
• Implement worker plugins that perform the billable service and return a microUSDC amount
• Use @x402/x402-js to sign a payment receipt and submit to the x402 gateway on Base
• Update the task record to 'paid' on success or 'error' on failure, with retry logic

证据

x402 is a lightweight protocol that lets you attach a payment requirement to an HTTP endpoint.

USDC on Base confirms in ~2 seconds; no waiting for batch payouts.

Base transaction cost ≈ $0.0001, far below the $0.01–$0.10 per‑call price I target.
