# Service Implementation (SDK) If you want to have **full control over the layout** and design the Fashion Hub components the way that best fits your application — or even implement the solution inside **native mobile apps** — you can use our official SDK. The SDK allows you to directly interact with all Fashion Hub services, including product data handling, size recommendations, and tracking events, while giving you complete freedom on how to render and structure your UI. For more details and examples of usage, check the package documentation on npm:\ --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.sizebay.com/fashion-hub/service-implementation-sdk.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
