+
+// Enhanced methods
+clearRequestTimeouts() { /* cleanup logic */ }
+setLoading(loading) { /* loading state management */ }

+## Authentication
+All API endpoints require authentication unless specified otherwise. Authentication is handled via JWT tokens.
+
+### Authentication Headers
+```http
+Authorization: Bearer <jwt_token>
+Content-Type: application/json

+
+## Base URL
+```
+Development: http://localhost:3000/api
+Production: https://your-domain.com/api
