A visual thesis for composable intelligence
Four agents.
141 services underneath.
Nanocodex, Codex, Claude Code, and Pi can discover a service, call its ordinary HTTP API, receive a 402, and settle it. Direct providers and integration gateways make the paid surface much larger than any one vendor graph.

What the graph actually says
Discovery is open. Settlement is local.
mpp.dev publishes discovery metadata; the target service’s runtime 402 Challenge remains authoritative. Orthogonal and Pay With Locus each expose 42 cataloged routes, while first-party and Tempo-hosted endpoints offer another integration path.
