Exposing Image OCR and Auto-Tags to External Crawlers via Graph API

I am using an external integration (ServiceNow) that crawls a SharePoint Online library via the Microsoft Graph API.The external crawler only sees basic file metadata. I need it to see the extracted text (OCR) and Auto-Tags that SharePoint generates for images.

Is there a way to force these "hidden" media properties into a standard searchable column (like description) so an external crawler can "see" them as text?

    The available context only documents how SharePoint search exposes content through crawled and managed properties inside SharePoint’s own search index. It does not describe any mechanism to:

    • Surface SharePoint’s image OCR text or Auto-Tags into standard list columns (such as Description), or
    • Expose those search-only properties through Microsoft Graph so that an external crawler (like ServiceNow) can read them as regular metadata.

    From the provided information, only the built-in managed properties and their mappings are described, and these are used by SharePoint’s internal search, not by Graph-based file metadata access. No supported method is documented here to “force” those hidden media/search properties into a normal column that Graph would return.
