+## API Integration
+
+The frontend communicates with two backend services:
+
+- **Auth Service** (default: http://localhost:8001)
+  - `/auth/register` - User registration
+  - `/auth/login` - User login
+  - `/auth/refresh` - Token refresh
+  - `/auth/me` - Get current user
+
+- **API Service** (default: http://localhost:8000)
+  - `/api/v1/accounts` - Account CRUD operations
+  - `/api/v1/accounts/{id}/tasks` - Task management
+  - `/api/v1/accounts/{id}/signin-logs` - Signin logs
+

+
