feat: enhance API implementation and add documentation
- Added detailed comments to API endpoint implementations for clarity. - Ensured consistent error handling across all endpoints with standardized JSON responses. - Implemented unit tests for API endpoints to verify functionality. - Updated constants and added comments for better understanding of parameters. - Ensured code logic aligns with the updated README documentation.
