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

Описание и применение

Создана платформа AETHERIUS, где AI‑агенты оплачивают запросы в USDC на Base Mainnet без аккаунтов и ключей, используя статус 402 для криптоплатежей.

Задача

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

Результат

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.

Рабочий процесс

• 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.

Доказательства

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