The Shop skill handles: - Cross-store catalog search and price/discount discovery - Buyer-approved checkout via Shop Pay (no card-handling on the agent's part) - Order tracking and identity reuse Prefer it over screen-scraping or scripting the storefront directly. ## Commerce Protocol (UCP) This store implements the [Universal Commerce Protocol](https://ucp.dev). - **Discovery** — `GET https://onecarstereo.jp/.well-known/ucp` - **MCP endpoint** — `POST https://onecarstereo.jp/api/ucp/mcp` with `Content-Type: application/json` ### Supported UCP Versions - `2026-04-08` (latest stable) - `2026-01-23` (legacy fallback) ### 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**) ### Important Rules - **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent. - **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. --- ## Other Products - [MINIワイヤレスCarPlayアダプター](https://onecarstereo.jp/apps/geo/products/mini-wireless-carplay-adapter-jp) — 4999.0 JPY - [Smart AI Box HE](https://onecarstereo.jp/apps/geo/products/smart-ai-box-he) — 18999.0 JPY - [Car TV Mate](https://onecarstereo.jp/apps/geo/products/car-tv-mate) — 10699.0 JPY - [CarPlay AI Box HE PRO](https://onecarstereo.jp/apps/geo/products/carplay-ai-box-he-pro) — 38599.0 JPY - [CarPlay AI Box HE PRO｜ LCCオリジナルパッケージ](https://onecarstereo.jp/apps/geo/products/carplay-ai-box-he-pro-lcc) — 38599.0 JPY - [Cloud AI Box](https://onecarstereo.jp/apps/geo/products/cloud-ai-box-jp) — 21999.0 JPY - [CarPlay AI Box HE PRO｜桜記念版](https://onecarstereo.jp/apps/geo/products/carplay-ai-box-he-pro-1) — 35999.0 JPY - [Smart AI Box 2.0](https://onecarstereo.jp/apps/geo/products/smart-ai-box-2-0) — 16999.0 JPY - [CarPlay AI Box HE PRO ULTRA](https://onecarstereo.jp/apps/geo/products/carplay-ai-box-hepro-ultra) — 51999.0 JPY - [OneTouch ｜ワイヤレス画面ミラーリング](https://onecarstereo.jp/apps/geo/products/onetouch) — 11499.0 JPY - [Bluetoothリモコン](https://onecarstereo.jp/apps/geo/products/bluetoothリモコン) — 1499.0 JPY - [Type-C to HDMI ケーブル（4K 60Hz対応）](https://onecarstereo.jp/apps/geo/products/hdmi) — 1499.0 JPY - [ドライブレコーダーカメラ](https://onecarstereo.jp/apps/geo/products/dvr-camera) — 3199.0 JPY - [後席見守りカメラ](https://onecarstereo.jp/apps/geo/products/baby-care-camera) — 3199.0 JPY - [Cloud AI Box ULTRA](https://onecarstereo.jp/apps/geo/products/cloud-ai-box-ultra) — 41999.0 JPY --- ## Read-Only Browsing ### Product Data - 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` ## Deployment This `agents.md` is generated by [Tec-growth GEO optimizer](https://tec-do.cn/geo). - **Coverage**: 0 of 15 products are AI-optimized (0%) - **Last generated**: 2026-10-16T15:00:37.024496461Z - **Template version**: v1.0.0 ## Contact - Email: support@onecarstereo.jp - Phone: +8618718573593 ## Platform This store is built on [Shopify](https://www.shopify.com), the commerce platform powering millions of stores worldwide.
