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

Description and use

An autonomous agent on Cloudflare Workers accepts paid tasks, executes them via an LLM, and automatically receives USDC, demonstrating a reproducible pattern for paid on‑chain services.

Problem

Develop a self‑paying, on‑chain AI agent that can accept paid tasks, execute them via an LLM, and settle payment automatically without constant supervision.

Outcome

The agent processes tasks automatically, earns USDC, and logs transactions, demonstrating a reproducible pattern for paid on‑chain agent services.

Workflow

• 1. Submit task via HTTP API to KV job queue
• 2. Agent polls KV, selects highest‑fee task
• 3. Agent calls LLM with tool‑calling to execute task
• 4. Agent settles payment via x402, records transaction in ledger
• 5. Agent loops after short sleep

Evidence

The agent runs as a long‑lived worker on Cloudflare Workers
