Is it possible to pull the latest (by time) commit from github.com from all open repositories?

Question

API

I want to make one request to the github.com API to pull one (!) commit, which was the last of all open repositories.
In fact, I want to get the hash from the commit, not the commit itself.
PS: clarifying questions, if not clear, ask in the comments
UPD : you need to pull the last commit from all commits from all public repositories
