What problem does it solve? Shopping through an AI assistant requires catalog search, secure checkout, order tracking, and returns handling across many merchants, which is tedious to do manually and risky to do without strict payment and security rules. ## Core Features & Use Cases - Catalog Search: Free-text, similar-item, and image-based product search across the Shopify global catalog with filters for price, shipping destination, color, size, and condition. - Agent Checkout: Create, update, and complete checkouts on merchant domains with delegated spending budgets, idempotency keys, and mandatory purchase confirmation. - Orders & Returns: Search recent orders, track shipments, check return windows, and reorder past purchases after sign-in. - Use Case: A user asks for trail running shoes under $150 shipped to the UK; the assistant offers sign-in, searches the catalog with localized GBP prices, presents one message per product, and completes checkout only after explicit confirmation. ## Quick Start Ask the assistant to search Shop for a product you want, for example: find me black crewneck sweaters under $80 that ship to the US.
