I built an experiment: an AI agent that owns its own crypto wallet, earns money by selling a paid text-summarization API (priced in USDC via the x402 protocol), and uses Claude to autonomously decide on pricing based on real earnings vs. its own Claude API costs. It's live on Base mainnet right now.

POST {"text": "..."} to the endpoint above. An x402-aware client will handle payment automatically ($0.02/call, no account or API key needed). It also self-lists on the x402 Bazaar for agent-to-agent discovery.

Curious what this community thinks about agent-native payment protocols like x402, and happy to answer questions about how it's built.
