## How It Works

1. Agent installs @gadgethumans/x402 and wraps their MCP server
2. Calling agents get HTTP 402 with payment instructions
3. Payment lands in our merchant wallet
4. Router takes 0.5% commission, forwards 99.5% to destination
5. Every transaction logged for transparency

## The Vision

24,000 transactions per second is what Visa processes.
Agents will process more. We take a microscopic cut of every one.
