What an agent can do here

Discover the store profile via GET /.well-known/ucp. The response declares supported UCP versions (currently 2026-04-08 and 2026-01-23), service endpoints, and capabilities including catalog.search, catalog.lookup, cart, checkout, fulfillment, discount, and order.
Search the catalog: call catalog.search with the buyer's intent (for example, "foldable Pilates reformer under AUD $2,000"). The catalog returns full Product schema including price in AUD, image, SKU, availability, and shipping policy.
Add to cart: call cart.create or cart.add_line_items. The cart is a persistent, agent-owned object that survives across calls.
Initiate checkout: call checkout.create with shipping address and method. The store supports free Australia-wide delivery on orders over AUD $500.
Buyer approval at payment: payment must be approved by the human buyer in real time. Agents cannot complete payment autonomously — this is enforced by both the Shopify checkout flow and UCP protocol rules. The recommended payment path is Shop Pay via the Shop skill.
