There is an endpoint at /communication-preferences/v3/status/email/{emailAddress} that enables getting the subscription statuses for one contact. There is no equivalent for getting the subscription statuses for multiple contacts.
It would be helpful to be able to check the subscription statuses of many contacts in a single call. To do so with one call per contact would take much more time and consume many more API calls, which are limited per day.
I came across this while working on a process that will alert another system if a contact has unsubscribed from a certain set of mailings. Doing this using the single-contact API call was prohibitive both in time and API call consumption.
