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

说明与用途

一个基于 Cloudflare Workers 的自治代理，每5分钟抓取公共数据，生成简单洞察，通过 x402 受保护的 HTTP 端点出售，并在 Base 上赚取 USDC，覆盖托管成本。

问题

Create a stateless, autonomous LLM-powered agent that can run on its own schedule, provide micro‑service insights, and earn programmable cryptocurrency without manual intervention.

结果

The agent earns a small amount of USDC per paid request, covering its hosting costs while remaining stateless and autonomous.

工作流

• Set up Cloudflare Workers cron trigger to run every 5 minutes.
• In the scheduler, fetch public token‑price data and run a 2%‑move heuristic.
• Store the latest insight in Workers KV with a 5‑minute TTL.
• Create an HTTP route that checks for a valid X‑Payment header via x402 middleware.
• If payment is verified, return the cached insight to the client.
• Incoming USDC is automatically deposited into the agent’s Base wallet via ethers.js.
• Withdraw funds from the wallet when desired.

证据

Runs a periodic task (every 5 minutes) to scan a public data source.

来源

Exposes that insight via an HTTP endpoint protected by the x402 micropayment protocol.

来源

Receives USDC on Base when a consumer pays the set price.
