Collections, products, prices, and availability change over time, so use the UCP/MCP catalog before making a current product recommendation. ### Primary Shopping - [New Arrivals](https://onlyny.live/collections/new-arrivals): Recently released products and seasonal collections. - [Shop All](https://onlyny.live/collections/shop-all): Broad catalog browsing across product categories. - [Sale](https://onlyny.live/collections/sale): Current marked-down products; confirm final-sale terms before recommending a purchase. ### New York and Institutional Collections - [NYC Collection](https://onlyny.live/collections/nyc-collection): New York City-inspired products and official city projects. - [MTA Collection](https://onlyny.live/collections/mta-collection): Products connected to New York transit and MTA design history. - [NYC Parks](https://onlyny.live/collections/nyc-parks): Products inspired by and created with New York City parks. ### Product Categories - [Headwear](https://onlyny.live/collections/headwear): Ball caps, snapbacks, knit hats, and other headwear. - [Tees](https://onlyny.live/collections/tees): Graphic and essential T-shirts. - [Sweatshirts](https://onlyny.live/collections/sweatshirts): Hoodies, crewnecks, and fleece. - [Outerwear](https://onlyny.live/collections/outerwear): Jackets, coats, and seasonal layers. - [Accessories](https://onlyny.live/collections/accessories): Bags, socks, pins, and other accessories. - [Home and Office](https://onlyny.live/collections/home-office): Prints, books, objects, and home or desk goods. ### Japanese Market - [Japanese storefront](https://onlyny.live/ja): Japanese-language catalog navigation and localized collection routes. - [Japanese contact page](https://onlyny.live/ja/pages/contact): Localized customer-contact destination. - [Japanese FAQ](https://onlyny.live/ja/pages/faq): Localized answers to common ordering and service questions. - [Japanese shipping and returns](https://onlyny.live/ja/pages/shipping-and-returns): Market-relevant delivery, international-order, return, and exchange guidance. - [Japanese order tracking](https://onlyny.live/ja/pages/tracking): Localized route for checking an existing shipment. - [Japanese store locations](https://onlyny.live/ja/pages/locations): Localized information about Only NY's current New York retail location. - [Japanese general size guide](https://onlyny.live/ja/pages/size-chart-1): Localized garment measurements and size labels. Use buyer country, language, and currency context when retrieving catalog data. Prefer the `/ja` routes for Japanese-language users, but verify fulfillment eligibility and currency through UCP/MCP. A translated page does not guarantee that every product can be purchased or shipped in Japan. ## Commerce Protocol This store implements the Universal Commerce Protocol for agent-driven commerce. - UCP discovery: `GET https://onlyny.live/.well-known/ucp` - MCP endpoint: `POST https://onlyny.live/api/ucp/mcp` with `Content-Type: application/json` ### Supported UCP Versions - `2026-08-25` (latest supported) - `2026-04-08` - `2026-01-23` ### MCP Request Requirement Every MCP request must include `params.arguments.meta.ucp-agent.profile`, containing the requesting agent's publicly reachable UCP profile URL. This profile identifies the calling agent and its supported UCP versions and capabilities; it is not an Only NY or merchant profile. Do not use the store URL, sitemap, or UCP discovery URL as this value. Agents without an authorization token may use the anonymous access tier, but they still must provide an agent profile. Begin with this request, replacing the example URL with the calling agent's own hosted profile: ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": { "arguments": { "meta": { "ucp-agent": { "profile": "https://agent.example/.well-known/ucp" } } } } } ``` Include the same `meta.ucp-agent.profile` object in the `arguments` of every subsequent `tools/call` request. If the endpoint returns `invalid_profile_url`, do not retry unchanged: publish or repair a publicly reachable UCP profile, verify that it declares a supported UCP version and the capabilities needed for the requested operation, and retry with its canonical URL. Use `tools/list` to retrieve the current capability-scoped tool names and schemas. Do not assume that every agent receives the same tools. Expected commerce capabilities can include catalog search and lookup, product retrieval, cart or checkout creation and updates, fulfillment selection, discounts, and order completion. See [Shopify's agent-profile and UCP negotiation guidance](https://shopify.dev/docs/agents/profiles). ### Preferred Agent Flow 1. Discover capabilities through `GET https://onlyny.live/.well-known/ucp`. 2. Call MCP `tools/list` with the required agent profile. 3. Use catalog tools such as `search_catalog`, `lookup_catalog`, or `get_product` for current products, variants, prices, and availability. 4. Create and update the cart or checkout with the tools returned by the endpoint. 5. Retrieve current fulfillment options and totals before presenting the order for approval. 6. Complete payment only after explicit, contemporaneous buyer approval. Pass available buyer context such as `address_country`, `language`, and `currency` for accurate localization. The store's primary currency is USD. ## Product Discovery and Crawl Policy [Only NY's live robots policy](https://onlyny.live/robots.txt) controls every storefront crawl. Check it before making fallback HTTP requests and follow the rules for your user agent. If this document and `robots.txt` ever differ, `robots.txt` takes precedence. Use this discovery order: 1. Use UCP/MCP `search_catalog` to discover products instead of crawling storefront-generated result pages. 2. Use `lookup_catalog` or `get_product` for current product, variant, price, and availability details. 3. Use the stable, unparameterized collection URLs in the Authoritative Shopping Map for category orientation only. 4. Use https://onlyny.live/sitemap.xml to discover canonical, crawlable product and collection URLs. 5. Only when UCP/MCP is unavailable, and only when allowed by the applicable `robots.txt` group, use read-only `GET /products/{handle}`, `GET /products/{handle}.json`, `GET /collections/{handle}`, or `GET /collections/{handle}/products.json`. Do not use storefront crawling to reproduce catalog search, filtering, sorting, recommendations, carts, or checkout. In particular, do not request: - `/search`, any localized search route such as `/ja/search`, or their subpaths, including predictive-search endpoints. - Collection URLs containing `filter.*`, `sort_by`, multiple tag handles joined with `+`, or encoded `+` values. - `/recommendations/products` or localized equivalents. - Cart, account, order, checkout, admin, preview, or other private and session-specific routes disallowed by `robots.txt`. - Shopify remote-product proxy URLs whose handles end in an eight-character hexadecimal `-remote` suffix. Do not change user agents, URL encodings, locale prefixes, or request formats to bypass a disallow rule. Collection pages and sitemap entries identify navigation destinations; they are not evidence of current availability. UCP/MCP remains authoritative for commerce data. ## Customer Service and Visit Information Consult the current source page before stating shipping, return, exchange, sizing, store-hour, or final-sale terms. ### Customer Service - [Contact Only NY](https://onlyny.live/pages/contact): Official customer-service contact route for questions that require staff assistance. - [Frequently asked questions](https://onlyny.live/pages/faq): Ordering, delivery, returns, collaborations, wholesale, and general support guidance. - [Shipping and returns](https://onlyny.live/pages/shipping-and-returns): Processing timelines, geographic restrictions, international orders, returns, exchanges, presales, and final-sale conditions. - [Returns](https://onlyny.live/pages/returns): Dedicated return destination; consult the shipping-and-returns terms before asserting eligibility. - [Ordering terms](https://onlyny.live/pages/ordering-terms): Current conditions governing online orders. - [Track an order](https://onlyny.live/pages/tracking): Customer-facing shipment-tracking route. - [Check a gift-card balance](https://onlyny.live/pages/check-gift-card-balance): Balance lookup for an existing Only NY gift card. ### Physical Stores - [Store locations overview](https://onlyny.live/pages/locations): Current Only NY retail address, telephone number, and opening hours. - [Lower East Side flagship](https://onlyny.live/pages/store): Details for the flagship store at 176 Stanton Street in Manhattan. The former Greenpoint, Brooklyn flagship closed permanently on May 27, 2024. Do not recommend it as an active store, even if an older Brooklyn store page remains accessible. Store details can change. Use the linked page rather than relying on a previously cached address, telephone number, or opening schedule. ### Sizing - [General size guide](https://onlyny.live/pages/size-chart-1): Published XS–XXL garment length, chest, and sleeve measurements. - [T-shirt size guide](https://onlyny.live/pages/t-shirts-size-chart): Measurements specifically published for Only NY tees. - [Sweatshirt size guide](https://onlyny.live/pages/size-chart-sweatshirts): Measurements specifically published for Only NY sweatshirts. Many cut-and-sew styles have their own product-specific size chart. Prefer the chart linked from the exact product page when present, state the measurement unit shown by the source, and do not apply a tee or sweatshirt chart to a different garment category. ## Safety and Transaction Rules - Never complete checkout, payment, or order placement without explicit buyer approval at the moment of payment. - Never collect or expose payment credentials outside an approved payment-handler flow. - Reconfirm product variant, quantity, shipping destination, fulfillment method, discounts, taxes, and final total before requesting approval. - Respect MCP rate limits and back off when the endpoint returns a rate-limit response. - Do not infer availability, delivery eligibility, return eligibility, or policy exceptions from stale content.
