How I Built an Autonomous AI Agent That Earns USDC While I Sleep

Описание и применение

Создана статeless‑сервис на FastAPI, который принимает запросы на суммирование текста, проверяет микроплатежи через x402 и автоматически зарабатывает USDC на сети Base.

Задача

Developers want to monetize a stateless AI service via micropayments without complex invoicing.

Результат

A fully functional, stateless AI summarization service that earns USDC automatically, with minimal code and no manual invoicing.

Рабочий процесс

• 1. Set up FastAPI app with x402 header validation.
• 2. Load AI summarization model at startup.
• 3. Verify x402 payload, signature, and nonce for each request.
• 4. Run summarization and return result if payment verified.
• 5. Use a lightweight script or The Graph to poll USDC contract for earnings.
• 6. Optionally schedule background tasks for model warm‑up or cache priming.

Доказательства

Run a stateless HTTP endpoint that performs a useful AI task and charge callers a tiny USDC fee via the x402 protocol; the agent simply watches its balance grow.
