 - `apiBase`: The base path of all API endpoints. The service may be hosted on a subpath of the main domain, e.g., _/public-api/iam/v3_, then the apiBase is _/public-api_ in this case. If the original api path from the OpenAPI specification is acceptable, you don't need this field.
 - `crossOrigin`: Whether to use the absolute api path when calling the service. This is useful when the service is hosted on a different domain and you need to set the `Access-Control-Allow-Origin` header. Default is `false`.
 - `output`: The output directory for the generated code. The default is `./src/api/{id}`.
