How to find the location of all users of a specific GitHub repository

Keywords: git api url github github-api-v3

Question: 

I would like to get in a single call the location of all the developers of a specific GitHub repository.

I read these pages without finding the solution:

https://developer.github.com/v3/users/

https://help.github.com/en/articles/searching-users

for now I can get information about the location of a single user, for example:

https://api.github.com/users/gigi

unfortunately to get information on all the developers of a specific repository I can't make calls for every single developer, this because because the process becomes too long and GitHub doesn't allow to make too many calls at once.
