     *   **Sidebar:** (`src/components/Sidebar.astro`) Contains account selection dropdown and a collapsible section for adding new transactions. Includes an account summary section.
     *   **Main Content:** (`src/components/MainContent.astro`) Displays the header with the current account name and the transaction list.
 *   **Components:** Separate Astro components exist for major UI sections (Sidebar, MainContent, TransactionTable, AddTransactionForm, AccountSummary).
-*   **Data Loading:** Currently using empty arrays for accounts and transactions, initialized in `src/pages/index.astro`.
+*   **API Integration:** 
+    *   API routes structure implemented in `src/pages/api/`
+    *   Temporary data store in `src/data/store.ts`
+    *   GET /api/accounts endpoint implemented and integrated with frontend
 *   **Account Switching:** Selecting an account from the dropdown in the sidebar correctly updates the Main Content area (header, transaction table) and the Account Summary section using client-side JavaScript (`<script>` tag in `index.astro`).
 *   **Collapsible Form:** The "Add Transaction" section in the sidebar (`src/components/AddTransactionForm.astro`) can be expanded and collapsed using client-side JavaScript (`<script>` tag in `AddTransactionForm.astro`).
 *   **Basic Formatting:** Utility functions (`src/utils.ts`) exist for formatting currency and dates, used both server-side and client-side (mirrored in `index.astro` script).

 ## Next Steps & TODOs
 
-1.  **Backend API Integration:**
-    *   Define the expected API endpoints (e.g., `GET /api/accounts`, `GET /api/accounts/:id/transactions`, `POST /api/transactions`, `PUT /api/transactions/:id`, `DELETE /api/transactions/:id`).
-    *   Replace static JSON data fetching in `index.astro` with `fetch` calls to the backend API during server-side rendering (or potentially client-side, depending on strategy).
-    *   Update client-side logic to interact with the API for CRUD operations.
+1.  **Complete API Implementation:**
+    *   Implement remaining API endpoints:
+        *   GET /api/accounts/:id
+        *   GET /api/accounts/:id/transactions
+        *   POST /api/transactions
+        *   PUT /api/transactions/:id
+        *   DELETE /api/transactions/:id
+    *   Add error handling and validation
+    *   Prepare for future database integration
 2.  **Implement Create Functionality:**
     *   Add client-side JavaScript to the `AddTransactionForm.astro` component (or enhance the script in `index.astro`) to handle form submission.
     *   Prevent default form submission.
