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.
