API Call Item Entity - call multiple items at once

Summary:

Is there a way to call multiple items at once or can this only be done one item at a time? We want to use API call below to see if item exist or not in WMS. This will determine if integration sends a Create or Update action code. We are facing integrations issue where records are failing in WMS due to action code Update when the items are not in WMS yet. To prevent performance issues, how can we check multiple items at once?
