Overview

The Validate Emails endpoint checks if email addresses exist in the Minerva database and provides validation status and last seen date information. This endpoint accepts a simple list of email address strings and returns match status, validation status, and last seen timestamps for each email. The endpoint automatically handles email normalization and will attempt to match both the original email and any sanitized versions against the Minerva database.
