Bulk Exporting Subscription Status via API

Our current CRM is on premise and not directly integrated with Eloqua. We have been through an Eloqua program deleting records that are globally unsubscribed on a weekly basis. We would like to update our CRM with the subscription status of these records.

Is it possible through the API to reference email addresses in our CRM database against Eloqua and return their subscription status even if the record has been deleted from the Eloqua database? I know that the subscription status is saved even if the record is deleted in case they are re uploaded to the system.

Thank you
