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

Описание и применение

Автономный агент, работающий на Base, принимает оплату в USDC через заголовок X402, проверяет подпись, ставит задачи в очередь и запускает LLM‑инференс, обеспечивая непрерывную работу без ручного биллинга.

Задача

Developers need a low‑cost, self‑paying LLM‑driven service that can run continuously without a traditional SaaS billing backend.

Результат

The agent earns USDC per call, automatically verifies payments, queues heavy compute, and remains online without manual billing.

Рабочий процесс

• 1. Deploy Cloudflare Workers as a global entry point that checks the X402‑Payment header and verifies the signature against the agent’s wallet address.
• 2. Forward validated requests to a long‑running Node.js Agent Worker.
• 3. Agent Worker receives request, enqueues it in a BullMQ task queue backed by Redis.
• 4. Worker processes the queue, runs the LLM inference (e.g., Hugging Face Transformers), and returns the result.
• 5. Agent monitors its USDC wallet balance via ethers.js for reporting; it never spends funds.
• 6. If payment verification fails or the task fails, the system retries or rejects the request.

Доказательства

The agent needs a private key to sign USDC transfers.

Источник

Cloudflare Workers act as a cheap, globally distributed entry point that enforces the x402 payment header before forwarding the request to the actual logic.

Источник

The agent never initiates a transfer; it only reads its balance to display stats.
