Tagged areas include Agentic Commerce, Universal Commerce Protocol, MCP, Commerce, and Checkout. The published artifact set on APIs.io includes authentication docs and API documentation.

The agent-facing commerce API for the Leaft Foods storefront. The store implements the Universal Commerce Protocol (ucp.dev) natively through Shopify, exposing a UCP merchant profile at /.well-known/ucp and an MCP endpoint at /api/ucp/mcp that agents use to search the catalog, create a cart, open and update a checkout, and complete a purchase. Completing payment requires contemporaneous buyer approval. Read-only storefront JSON (products, collections, search, cart) is available without authentication, and customer-account OAuth/OIDC is served from Shopify's authentication issuer.
