  title: Shop ICON Storefront Catalog API
  version: '2026-08-22'
  description: 'Anonymous, read-only JSON access to the Shop ICON storefront at store.iconaircraft.com — the ICON Aircraft merchandise store (A5 apparel, hats, scale models, publishing and flight-training products), built on Shopify.

    ICON Aircraft publishes no developer program and no product API for the A5 aircraft itself. This storefront surface is nonetheless a genuine, documented, machine-readable interface: the store''s own /agents.md and /robots.txt name these endpoints as the supported read path for AI agents, and each one was probed live and returned 200 without credentials on 2026-08-22.

    Ownership is established from the storefront''s own metadata rather than the fetch URL: GET /meta.json returns name "Shop ICON", domain store.iconaircraft.com, myshopify_domain iconaircraft.myshopify.com, and city Vacaville, California — ICON Aircraft''s headquarters. The store also stocks Flight Design branded merchandise, consistent with Flight Design being ICON Aircraft''s sister company under Shang Gong Group.

    Derived by API Evangelist from https://store.iconaircraft.com/agents.md and from live anonymous probes of every operation below. The transactional surface (cart, checkout, order) is NOT described here — Shopify exposes it to agents through the UCP/MCP endpoint instead; see mcp/icon-aircraft-mcp.yml.'

      description: Returns the cart bound to the caller's Shopify session cookie. An anonymous caller with no prior session receives a new empty cart. Agents should prefer the UCP/MCP cart tools over this endpoint — see mcp/icon-aircraft-mcp.yml — because checkout on this storefront requires contemporaneous human approval and cannot be completed through the storefront JSON surface.
