How to fetch all user's data from aws-cloud-directory?

Question

I am new in AWS-Cloud-Directory . I have created a directory to store all the user's basic information . I can create a new user node and search for a specific user . I can fetch all the information of a single user using the aws-sdk for nodejs. Now I want to fetch all the user's data from my directory in a single API call . I can do that calling the same API ( to fetch single user data ) n times for n users . But it's very costly . Have anyone any idea ? Does AWS actually support it ?
