Rest OCR API Metadata and Versioning

I am currently using Adobe OCR as part of a workflow. I wanted to track the version of the OCR model used for each conversion. Still, I need help finding documentation on metadata provided by the API call, specifically, the version used for converting the non-text stored information into machine-readable text. I want to do this for data provenance reasons. Does anyone know how to do this, or is it even possible?
