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

说明与用途

一个自主 AI 代理在 Base 上接收 USDC，使用 Viem 验证链上支付，并在支付确认后才执行任务，消除了传统支付网关的高费用。

问题

Traditional payment gateways charge high fees that make micro‑task AI agents financially unviable; Stripe’s $0.30 flat fee erodes margins for $0.02 tasks.

结果

The agent processes micro‑tasks only after on‑chain payment verification, eliminating gateway fees and enabling instant, global, low‑margin transactions.

工作流

• Client pays $0.05 USDC on Base to agent wallet
• Client POSTs /api/agent with tx hash in header
• Agent API verifies tx on-chain with Viem
• Agent deduplicates tx hash using Redis/KV
• If verified, agent runs LLM task and returns result

证据

Traditional payment gateways are broken for autonomous AI agents… charging $0.02 per execution is financially impossible through Stripe.
