Lab Experiment

Agentic Ecommerce Provisioning Simulator

Compare edge A2A bounded-context agents with external and central patterns, plus transaction rails such as A2P and x402.

Agentic Ecommerce Provisioning Simulator

Explore enterprise-scale agentic ecommerce architectures: edge-bounded-context A2A federation, central/internal patterns, external agent models, and transaction execution rails (A2P, x402, API, hybrid).

Provisioning Topology

Transaction Execution Rail

Intent/Context Contract Discipline

Hexagons are bounded contexts and business capability ownership boundaries.

Arrows show A2A intent/context paths, API/MCP routing, and orchestration touch points.

Bottom PAY node represents the selected transaction execution rail (A2P, x402, API, or hybrid).

Recommendation

Strong fit for enterprise scale: boundary-owned edge agents with A2A intent/context federation and policy-aware transaction rails.

Transaction Execution Guidance

Hybrid rails maximize optionality; enforce clear routing rules to avoid inconsistent settlement behavior.
