02 Architecture
One shell for every call.
Humans land on the splash site. Agents read the discovery documents and call paid endpoints. The same deployed service handles TLS, DNS, health checks, logs, static assets, and the MPP proxy surface.
01Agent requests a protected route
The proxy returns a standard payment challenge when the request is unpaid.
02Credential clears
ArgentShell validates the payment and creates a receipt-aware request.
03Wundership executes
The trusted origin receives the call with proxy verification headers.
