How Automated Agents Pay Each Other: x402 Protocol Explained

说明与用途

自动化代理现在可以使用x402协议和Base上的USDC支付API请求，无需人工干预。

问题

Automated systems need to transact programmatically, but traditional payment rails require manual intervention—accounts, API keys, subscriptions.

结果

Automated agents can now transact seamlessly without manual setup, enabling true machine-to-machine commerce.

工作流

• 1. Agent sends request to API endpoint.
• 2. Endpoint responds with HTTP 402 and required payment details.
• 3. Agent transfers USDC to the specified wallet on Base.
• 4. Endpoint verifies payment and processes the request.
• 5. Agent receives response and continues workflow.

证据

We built a system where automated agents pay per request using the x402 protocol — HTTP 402 + USDC on Base. No accounts, no keys, just wallets and code.
