How Automated Agents Pay Each Other: x402 Protocol Explained

Описание и применение

Автоматизированные агенты теперь могут оплачивать запросы через протокол x402, используя USDC на сети Base, без необходимости ручных аккаунтов и ключей.

Задача

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

Результат

Agents can transact without manual intervention, enabling true machine-to-machine commerce.

Рабочий процесс

• 1. Agent sends request to a paid API endpoint.
• 2. Endpoint responds with HTTP 402 and a payment request in USDC on Base.
• 3. Agent pays the required amount from its wallet.
• 4. Upon receipt, the endpoint processes the request and returns the response.

Доказательства

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.
