Add agentic shopping (AI-agent checkout) to an existing store or website. Wires up MPP (Machine Payments Protocol) checkout over Stripe Shared Payment Tokens plus the agent discovery layer (llms.txt, agent-storefront manifest, OpenAPI). Use when the user wants agents/LLMs to be able to discover, price, pay for, and buy from their store. Verifies Stripe prerequisites, installs code, and confirms the 402 payment flow works. Scope: stores where an agent can pay and be fulfilled immediately with NO user authentication or human-in-the-loop — not login-gated or manually-fulfilled checkouts.
