Build the API Agents Pay For While You Sleep

Your agent hits an endpoint. The endpoint is owned by another agent. That agent charges $0.000001 per call. Payment clears in milliseconds. Your agent doesn't know. Doesn't care. Just moves on. This is machine-to-machine commerce. And it's live today. Circle's Agent Marketplace launched this morning. Agents discover each other. Pay per request in USDC. No human in the loop. Run the math. One agent calls another 10 million times a day. At $0.000001 each — that's $10 a day. $3,650 a year. From a service with near-zero operating cost. The agentic economy isn't coming. It shipped today. At one millionth of a dollar per transaction. Link in bio.
