I Built an API Marketplace Where AI Agents Pay Per Request in USDC — 80 Endpoints in 4 Days, Solo

说明与用途

AETHERIUS 让 AI 代理在 Base 主网使用 USDC 付费调用 API，无需账户或密钥，利用 HTTP 402 进行加密支付。

问题

AI agents need to consume APIs without human sign‑ups, API keys or subscriptions, yet they can transact in crypto.

结果

Built solo in 4 days with $5.80 ETH, 80 live endpoints (60 paid, 20 free), 60/60 passing tests, Python & JavaScript SDKs, real USDC payments flowing on Base Mainnet.

工作流

• 1. Agent sends request to an endpoint. 2. Server responds 402 Payment Required with USDC amount. 3. Agent signs and submits USDC transfer on Base. 4. Server verifies payment via Coinbase CDP. 5. Server returns 200 OK with data.
• 6. Agent can query free x402 Intelligence endpoints for on‑chain analytics without payment.

证据

AETHERIUS solves this: An agent hits an API, gets a 402 Payment Required response with a USDC amount, pays on‑chain, and receives data.
