The gateway reports a p99 proxy overhead of 0.03ms under 100 concurrent requests, a Cerberus UCB1 router with 5 arms, and 12 active MCP tools, including a2a_delegation at $0.50 USDC per call and deep_stealth_browser at $0.05 USDC per call. The project claims 100% autonomous settlement and a $25.00 DaaS arbitrage profit.", "body_md": "# The Machine Economy \n\nRuns On x402\n\nDeterministic machine-to-machine payment tollbooths, sub-millisecond dynamic routing, and agent-to-agent delegation.
