Is there an API to get the the mappings of user from Active Directory to Okta?

I want to if there is any public API to get the below mapping. This is the mapping of user coming from AD to Okta. The API for this mapping is not available in Okta mapping APIs.
From the mapping APIs, only the expression of the mapping can be obtained. But I need an API to get the value of that expression for a given user.

If you’re mapping the AD attributes to Okta user profile, you can just retrieve the Okta user profile using the Users API.
