A2A + Remote MCP
Let the agent choose the product.
A2A agents can discover /.well-known/agent-card.json and send tasks to /a2a/v1. MCP clients can call recommend_paid_product, build_purchase_request, list_paid_products or get_purchase_instructions. The execute_paid_product tool can return the actual unpaid HTTP 402 quote, then forward a buyer-authorized x402 wallet signature to the same protected API, returning data only after verified settlement.
