modelApi property
ModelAPI is whether the plan reaches the World model endpoint and the SSE stream. The free floor is false, and that is what a catalog outage resolves to.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
bool? modelApi;
