Email Addresses using V8 API

Good Moring,
we need to retrieve for all accounts, retrieve all email addresses associated to account using V8 API.

I can retrieve them using first follow API

 V8/module/Accounts/{{account_id}}/relationships/email_addresses 

and then, foreach entry, call:

V8/module/EmailAddresses/{{email_address_id}}

I think that this is a heavy operation.

Is there a better solution?

Thank you so much

B.
