How Automated Agents Pay Each Other: x402 Protocol Explained

Описание и применение

Автоматизированные агенты теперь могут оплачивать запросы к API без ручного вмешательства, используя протокол x402 и USDC на Base.

Задача

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

Результат

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

Рабочий процесс

• 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.

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.
