Currently now github allows me to find the commits of a repo but in an organization there are many repos using this below

https://api.github.com/repos/OWNER/REPO/commits

I want to find the total of all the repos without looping through and summing all of them. Is there a faster way to get the total commits of an organization

i tried https://api.github.com/repos/OWNER/REPO/commits this for every repo but the time taken to run is very long so i wanted to find a better alternative.
