Prefer these endpoints over scraping the storefront: - UCP discovery: `GET https://barredefinition.com/.well-known/ucp` — supported versions, capabilities, and payment handlers. - MCP endpoint: `POST https://barredefinition.com/api/ucp/mcp` (`Content-Type: application/json`) — call `tools/list` to discover the available tools and their schemas. - Sitemap: https://barredefinition.com/sitemap.xml - Supported UCP versions: `2026-04-08`, `2026-01-23` Typical flow — introspect first: the tool names and schemas advertised by discovery are authoritative, not the labels below (Shopify is migrating cart capability from the Storefront MCP to the UCP Cart MCP, so don't hardcode tool names): 1. **Discover** — `GET /.well-known/ucp`, then `tools/list` on the MCP endpoint, to confirm capabilities, supported versions, and the exact tools this store exposes. 2. **Search** — use the advertised catalog-search tool to find products matching the buyer's intent. 3. **Cart** — create a cart and add the desired items. 4. **Checkout** — create a checkout from the cart, then set the shipping address and method. 5. **Complete** — finalize the checkout (the buyer must approve payment). Rules: - **Checkout requires human approval.** Never complete payment without explicit, contemporaneous buyer consent. - **Respect rate limits.** Back off on HTTP 429 responses. - **Pass buyer context** (`address_country`, `currency`) for accurate pricing and availability. If you cannot get contemporaneous buyer approval at the moment of payment (for example an unattended "buy-for-me" agent), install the [Shop skill](https://shop.app/SKILL.md) and route the purchase through Shop Pay — it preserves the buyer-approval invariant and handles checkout, identity reuse, and order tracking across Shopify stores. ## Browse without an agent key Read-only access, no authentication required: - All products: `GET /collections/all` - Product page: `GET /products/{handle}` · JSON: `GET /products/{handle}.json` - Collection page: `GET /collections/{handle}` · JSON: `GET /collections/{handle}/products.json` - Search: `GET /search?q={query}&type=product` - Sitemap: `GET /sitemap.xml` ## Most popular - [Whey Protein Powder](/products/whey-protein) — BEST FOR: Lean Muscle, Energy & Satiety High-protein.
