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

说明与用途

一个每15分钟运行一次的自治代理执行微任务，通过x402开具发票，并在Base上即时收到USDC，消除了人工批准和支付延迟。

问题

Monetizing LLM‑driven bots was hindered by human approval friction, unpredictable API costs, and slow fiat payouts.

结果

The agent autonomously performs micro‑tasks, invoices via x402, and receives USDC instantly on Base, eliminating human friction and cost uncertainty.

工作流

• Schedule cron to trigger agent
• Task runner selects a task from queue
• Run task and get result via LLM API
• Build x402 invoice with task details and amount
• POST invoice to x402 relay
• Relay verifies, escrows USDC, calls LLM if needed, returns signed receipt
• Store receipt and update agent balance

证据

I wanted a system where the agent could: Decide on a useful micro‑task, Execute that task autonomously, Receive payment instantly in a stablecoin (USDC) on a low‑fee L2 (Base).

Scheduler → Task Runner → pick task. Task Runner → LLM (via API) → get result. Task Runner → build x402 invoice. Task Runner → POST invoice to x402 Relay. Relay verifies signature, escrows USDC from its own wallet, calls the LLM, and returns a signed receipt.
