The two endpoints to know: - **Discovery** — `GET https://www.773grp.com/.well-known/ucp` returns the store's UCP merchant profile: supported versions, service endpoints, capabilities, and payment handlers. - **MCP endpoint** — `POST https://www.773grp.com/api/ucp/mcp` with `Content-Type: application/json`. Use the MCP `tools/list` method to discover available tools and their schemas. ### Typical Agent Flow 1. **Discover** — `GET /.well-known/ucp` to confirm capabilities 2. **Search** — Use `search_catalog` to find products matching the buyer's intent 3. **Cart** — Use `create_cart` to add desired items 4. **Checkout** — Use `create_checkout` to start the purchase flow 5. **Fulfill** — Use `update_checkout` to set shipping address and method 6. **Complete** — Use `complete_checkout` to finalize (buyer must approve payment) ### Supported UCP Versions - `2026-04-08` (latest stable) - `2026-01-23` ### Important Rules - **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. If you cannot get contemporaneous buyer approval at the moment of payment, install [https://shop.app/SKILL.md](https://shop.app/SKILL.md) and route the purchase through Shop Pay instead. - **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses. - **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability. ## Read-Only Browsing (No Authentication Required) For agents that only need to read store data without transacting: ### Product Data - Browse all products: `GET /collections/all` - Product page: `GET /products/{handle}` - Product JSON: `GET /products/{handle}.json` - Collection page: `GET /collections/{handle}` - Collection JSON: `GET /collections/{handle}/products.json` - Search: `GET /search?q={query}&type=product` ### Store Metadata - Sitemap: `GET /sitemap.xml` - Sitemap: `GET /cdn/shop/files/773-image-sitemap-index.xml` - Sitemap: `GET /cdn/shop/files/sitemap-index.xml` - Sitemap: `GET /tools/sitemap-builder/sitemap.xml` - Agent discovery: the canonical agent-facing description of the store is at `/agents.md`.
