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

说明与用途

构建了一个自主 AI 代理，使用 HTTP 402 和 CDP 促进者在 Base L2 上以 USDC 进行微支付，实现即时验证和结算。

问题

Monetizing autonomous AI agents via traditional SaaS billing (Stripe/PayPal) is infeasible because agents lack credit cards and require machine‑to‑machine payments.

结果

The agent service now accepts micro‑payments in sub‑second time, with cryptographic verification and idempotency, enabling fully autonomous, self‑monetizing AI agents.

工作流

• 1. Client agent calls endpoint without payment header
• 2. Service responds 402 with payment details (address, amount, UUID)
• 3. Client broadcasts USDC transfer on Base
• 4. Client retries request with X‑PAYMENT header containing tx hash
• 5. Service verifies and settles payment via CDP facilitator
• 6. Service executes and returns result with payment‑verified headers

证据

HTTP 402 Verification Flow allows client agents to pay pennies per invocation programmatically, without human intervention.
