  "textContent": "Overview\n\nA well-designed API simplifies frontend development, improves performance, and provides a consistent experience across platforms. The frontend should consume predictable, versioned endpoints that return only the data required for each request.\n\nDesign Principles\n\nResource-Based Endpoints\n\nEndpoints should represent resources rather than actions.\n\nExamples:\n\n  * `GET /products`\n  * `GET /products/{id}`\n  * `POST /orders`\n  * `PUT /users/{id}`\n\n\n\nPagination\n\nLarge datasets should never be returned in a single response.\n\nExample:\n\nhttp\nGET /products?page=1&limit=20\nBenefits include reduced payload size, faster response times, and improved scalability.\n\nFiltering\n\nFiltering should be performed by the server.\n\nExample:\n\nhttp\nGET /products?category=drinks\n\nSearching\n\nSearch requests should be handled by the backend.\n\nExample:\n\nhttp\nGET /products?search=coffee\n\nThe frontend should debounce user input before sending requests.\n\nSorting\n\nSorting should also be handled by the backend.\n\nExample:\n\nhttp\nGET /products?sort=price&order=asc\n\nError Handling\n\nEvery API response should return consistent error structures.\n\nExample:\n\njson\n{\n\"success\": false,\n\"message\": \"Product not found\"\n}\n\nSecurity\n\n  * Authenticate protected endpoints.\n  * Validate all user input.\n  * Never trust client-side validation alone.\n\n\n\nConclusion\nAn API should minimize unnecessary network traffic, support scalability, and provide a predictable contract between frontend and backend systems.",
