-## 📡 API Integration
+## 📡 API Integration (Standard Architecture)
 
-### Creating API Clients
+The project follows a strict **Service + Hook** pattern for API integration to ensure separation of concerns, type safety, and efficient caching.
 
-```tsx
-// src/lib/api/auth/login/queries.ts
-import { createApiClient } from "../create-api-client";
+**🏆 Golden Standard Reference:** [`src/lib/api/example`](src/lib/api/example)
 
-const api = createApiClient("/api/backend/auth");
+### 🏗️ Architecture Pattern
 
-export const loginUser = async (data: LoginDto) => {
-  const response = await api.post("/login", data);
-  return response.data;
+For every domain (e.g., `auth`, `users`), we strictly follow this 4-layer structure:
+
+| Layer | File | Purpose |
+|-------|------|---------|
+| **1. Types** | `types.ts` | **Contract:** pure TypeScript interfaces/DTOs matching Backend. |
+| **2. Service** | `service.ts` | **Logic:** Pure functions calling `apiRequest`. Independent of React. |
+| **3. Hooks** | `use-hooks.ts` | **State:** React Query wrappers (`useQuery`, `useMutation`) for caching & state. |
+| **4. Barrel** | `index.ts` | **Public API:** Central export point for the module. |
+
+### 📝 Implementation Guide
+
+#### 1. Define Service (`service.ts`)
+Uses `apiRequest` wrapper which handles client selection (`auth`, `core`, etc.), base URLs, and error normalization.
+
+```ts
+// src/lib/api/example/auth/service.ts
+import { apiRequest } from "@/lib/api/api-service";
+import { LoginDto, AuthResponse } from "./types";
+
+const login = (data: LoginDto) => {
+  return apiRequest<ApiResponse<AuthResponse>>({
+    url: "/auth/login",
+    client: "auth", // Selects the correct axios instance from clientMap
+    method: "post",
+    data,
+  });
 };
+
+export const authService = { login };
 ```
 
-### React Query Integration
+#### 2. Create Hook (`use-hooks.ts`)
+Wraps service in TanStack Query for loading states, caching, and invalidation.
+
+```ts
+// src/lib/api/example/auth/use-hooks.ts
+import { useMutation } from "@tanstack/react-query";
+import { authService } from "./service";
+
+export const AuthQueryKeys = {
+  all: ["auth"] as const,
+};
+
+export function useLogin() {
+  return useMutation({
+    mutationFn: (data: LoginDto) => authService.login(data),
+  });
+}
+```
+
+#### 3. Use in Components
+Components only interact with the Hooks, never the Service or Axios directly.
 
 ```tsx
-import { useQuery, useMutation } from "@tanstack/react-query";
+import { useLogin } from "@/lib/api/example"; // Import from barrel
 
-// Query hook
-export const useUsers = () =>
-  useQuery({
-    queryKey: ["users"],
-    queryFn: () => apiClient.get("/users"),
-  });
+export function LoginForm() {
+  const { mutate, isPending } = useLogin();
 
-// Mutation hook
-export const useCreateUser = () =>
-  useMutation({
-    mutationFn: (data: CreateUserDto) => apiClient.post("/users", data),
-  });
+  const handleSubmit = (data) => {
+    mutate(data, {
+      onSuccess: () => console.log("Logged in!"),
+    });
+  };
+}
 ```
