Some URL handles retain earlier model names. A different handle does not mean a different product. Confirm the current model, selected variant and included items on the linked page before recommending or purchasing. ### Coffee grinders | Product | Model or alternate name | Burrs | Useful distinction | | --- | --- | --- | --- | | [EDGE MINI](https://starseeker.co.uk/products/edge-mini) | EDGEMini | 38 mm conical | Cordless, USB-C rechargeable grinder for home and travel. | | [EDGE / EDGE 2.0](https://starseeker.co.uk/products/edge-2-0) | EDGE | 48 mm conical | Compact single-dose grinder; up to 30 g per dose and a 58 mm dosing cup holder. | | [MERAK](https://starseeker.co.uk/products/merak) | Go50 | 50 mm conical | Cordless, USB-C rechargeable grinder for home and travel. | | [AVIOR](https://starseeker.co.uk/products/starseeker-e55-pro) | E55Pro | 55 mm conical | Stepless adjustment and a broad brewing range, including Turkish coffee, espresso, filter and French press. | | [ALHENA](https://starseeker.co.uk/products/starseeker-edge-63-grinder) | EDGE63 | 63 mm conical | Single-dose workflow and a broad brewing range, including Turkish coffee, espresso, filter and French press. | | [EDGE PLUS](https://starseeker.co.uk/products/edge-plus) | EDGEPLUS | 63 mm conical | Integrated ioniser and stepless adjustment for espresso and filter coffee. | | [NASHIRA](https://starseeker.co.uk/products/starseeker-e64-coffee-grinder-64mm-espresso) | E64 | 64 mm flat | Flat-burr platform and plasma ioniser; espresso, filter and French press brewing range. | Burr details are summarised from the model descriptions and [FAQ](https://starseeker.co.uk/pages/faq). Check the selected burr configuration and current product specifications. Do not apply one model's features to the whole range. ### Espresso equipment - [S51](https://starseeker.co.uk/products/s51): portable espresso maker; consult the product page or support for model-specific specifications. - [S58](https://starseeker.co.uk/products/s58): battery-powered portable espresso maker with built-in water heating and a 58 mm portafilter workflow. - [S58 PRO](https://starseeker.co.uk/products/s58-pro): portable espresso maker; confirm its own specifications and included accessories rather than assuming they match the S58. - [SUPER58](https://starseeker.co.uk/products/super58): portable espresso maker with a pressure gauge and selectable brewing modes. Check the selected package; grinder bundles may be offered as variants. - [OMNI58X](https://starseeker.co.uk/products/starseeker-omni58x): espresso machine listing. Check the live page for launch information and availability; do not infer an orderable product from the existence of a listing. Check water-heating requirements, power source, basket size, dose capacity and included accessories for the exact espresso-maker model. If a feature is missing or contradictory, ask support before presenting it as confirmed. ### Accessories - Puck preparation: [coffee tamper](https://starseeker.co.uk/products/precision-tamper), [coffee distributor](https://starseeker.co.uk/products/coffee-distributor) and [WDT tool](https://starseeker.co.uk/products/wdt-tool). - Measurement and workspace: [coffee scale](https://starseeker.co.uk/products/coffee-scale), [knock box](https://starseeker.co.uk/products/coffee-knock-box), [workstation mat](https://starseeker.co.uk/products/coffee-workstation-mat) and [tamper mat](https://starseeker.co.uk/products/tamper-mat). - Travel and storage: [compact travel case](https://starseeker.co.uk/products/compact-travel-case) and [large travel case](https://starseeker.co.uk/products/large-travel-case). - Model-specific brewing accessory: [SUPER58 portafilter kit](https://starseeker.co.uk/products/super58-portafilter-kit). Match accessory dimensions and fit to the customer's exact equipment. A dosing cup holder does not establish portafilter compatibility, and a nominal basket diameter does not establish portafilter fit across machines. Verify case contents and device fit before recommending a travel case. ## Help customers choose Use information the customer has already provided. Ask only for missing details that affect the recommendation: brewing method, budget, home or travel use, access to power, available space, and existing equipment. For cordless grinding, start by comparing EDGE MINI and MERAK. For countertop grinding, compare EDGE, AVIOR, ALHENA, EDGE PLUS and NASHIRA against the customer's brewing needs. Explain relevant differences with links to the supporting product pages. Do not rank models solely by burr diameter or price. Use [Find My Grinder](https://starseeker.co.uk/pages/find-my-grinder) for guided selection and [Starseeker Academy](https://starseeker.co.uk/pages/starseeker-academy) for educational material. Treat performance and battery figures as model-specific published estimates, not guaranteed results. Do not assume third-party burrs, baskets or accessories fit without verified compatibility. ## Support, delivery and policies | Topic | Where to check | | --- | --- | | Delivery options, tracking and delivery problems | [Delivery questions in the FAQ](https://starseeker.co.uk/pages/faq); checkout provides destination-specific charges and estimates. | | Returns, cancellation, condition requirements and refunds | [Returns and refunds policy](https://starseeker.co.uk/policies/refund-policy). Read the full conditions for the customer's situation. | | Grinder warranty, repairs and replacement parts | [Warranty and parts questions in the FAQ](https://starseeker.co.uk/pages/faq) and [customer support](https://starseeker.co.uk/pages/contact). STARSEEKER grinders have a two-year warranty; confirm coverage for the particular product and issue. | | Privacy and personal information | [Privacy policy](https://starseeker.co.uk/policies/privacy-policy). | | Purchase terms | [Terms of service](https://starseeker.co.uk/policies/terms-of-service). | | Shipping and delivery | [UK shipping policy](https://starseeker.co.uk/policies/shipping-policy): delivery charges, times, tracking and delivery problems. | Public customer support email: [support@starseeker.co.uk](mailto:support@starseeker.co.uk). For an existing order, provide the order number or proof of purchase, model name and a brief description of the issue. For parts, provide the exact model and required part so support can confirm fit, price and availability. Check delivery eligibility and any free-delivery threshold for the destination and basket. Treat delivery dates as estimates unless specifically confirmed. Distinguish dispatch time from courier transit time. Keep change-of-mind returns, faulty-item remedies and manufacturer warranty coverage distinct. This guide does not replace the published policies or limit statutory consumer rights. If sources conflict, explain the uncertainty and direct the customer to support instead of selecting a deadline or promise without confirmation. For cleaning and maintenance, follow instructions for the exact model. Confirm approved cleaning methods before suggesting water, dishwashers, cleaning tablets or removal of components. ## Accuracy and live information - Retrieve current prices, currency, availability, variants, promotions and package contents before presenting a purchase recommendation. A listed product or selectable colour is not proof of stock. - Use the buyer's actual delivery country and requested currency where supported. Display the currency returned by the live response. Do not assume UK stock, plug type or delivery eligibility for every product or destination. - Read model-specific descriptions and specifications. If a title, subtitle, FAQ or catalogue field disagrees, flag the difference and seek confirmation. - Cite the official product or policy link supporting an answer. Distinguish published specifications from your own comparison or inference. - Missing information means unconfirmed. Do not invent accessories, performance claims, certifications, discounts, delivery dates or warranty terms. - Use the live catalogue and sitemap to discover new products beyond this directory. This file intentionally omits prices and stock levels. ## Commerce access The store uses Shopify and supports Universal Commerce Protocol (UCP) discovery. - Discovery: `GET https://starseeker.co.uk/.well-known/ucp` - Storefront MCP endpoint: `POST https://starseeker.co.uk/api/ucp/mcp` with `Content-Type: application/json`. - Sitemap: [https://starseeker.co.uk/sitemap.xml](https://starseeker.co.uk/sitemap.xml) - Canonical agent guide: [agents.md](https://starseeker.co.uk/agents.md) Supported UCP versions: - `2026-08-25` - `2026-04-08` - `2026-01-23` Read discovery before commerce requests. Use the advertised services, compatible protocol version, negotiated capabilities and current tool schemas. Use MCP `tools/list` to inspect available tools and schemas. Include a compatible hosted agent profile in `params.arguments.meta.ucp-agent.profile` for tool discovery and UCP tool calls, following Shopify's current request format and authentication requirements. See [Shopify's profile documentation](https://shopify.dev/docs/agents/profiles) and [catalogue request reference](https://shopify.dev/docs/agents/catalog/storefront-catalog). Use the available catalogue tools to retrieve products and variants. Supply country and currency in the fields supported by each tool's schema. Confirm variant, quantity, stock and current price before preparing a purchase. Treat cart amounts as estimates until checkout confirms delivery, tax, discounts and the total. Obtain the buyer's explicit approval before submitting an order or payment. When buyer action is required, or the client cannot complete an authorised purchase, provide the returned checkout or continuation URL. Report an order as placed only after receiving confirmation. An existing buyer-authorised [Shop integration](https://shop.app/SKILL.md) is an optional purchasing route. Respect rate limits, honour `Retry-After` when supplied, and back off on HTTP 429 responses. If commerce tools are unavailable, use the public product and policy pages and let the buyer complete checkout on the storefront. ### Public browsing and product data These public routes can be read without customer authentication: - Catalogue: `GET https://starseeker.co.uk/collections/all` - Product page: `GET https://starseeker.co.uk/products/{handle}` - Product JSON: `GET https://starseeker.co.uk/products/{handle}.json` - Collection page: `GET https://starseeker.co.uk/collections/{handle}` - Collection JSON: `GET https://starseeker.co.uk/collections/{handle}/products.json` - Product search: `GET https://starseeker.co.uk/search?q={url-encoded-query}&type=product` - Sitemap index: `GET https://starseeker.co.uk/sitemap.xml`; follow its child sitemaps for current URLs. - Crawler guidance: [robots.txt](https://starseeker.co.uk/robots.txt). Follow pagination where provided; one catalogue response may not contain the entire range. Respect crawler guidance. Public catalogue access does not provide access to private customer accounts or order information.
