Refactor parsers for better readability

**Feature request**
It would be great to have serialization for api.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_serialization` with default `false`.

The issue names no files, tests, or entry points. Start by locating the configuration handling for API serialization and trace how API output is produced. Done means defining the enable_serialization option with a default of false and implementing the requested serialization behavior, though the exact format is not specified.
