Create several requests at once in Postman - api

Question

I am trying to test GitHub API and explore it's different endpoints. I have the different possibilities which are returned by let's say the initial get request on https://api.github.com.
The returned list is:
{
"current_user_url": "https://api.github.com/user",
"current_user_authorizations_html_url": "https://github.com/settings/connectio ns/applications{/client_id}",

}
Is there a way into Postman, or follow up facilitators to generate a collection from these?. Some scripting will be necessary for sure to follow Postman Json Collection format.
If there is a solution other than Postman completely that fits in this issue, I am all ears.
What I did:
I tried to search for some GitHub API as a Postman Collection, I
didn't find any.
I tried to understand Postman Json Collection format, which is not so easy for me to write some script to create one. Maybe someone did?
I can "find and replace : "([a-z_])*": with curl -H "Authorization: token ####". Is there a way to integrate the whole to Postman?
I can't help it unless I consume a lot of effort. But also, I may be stuck other times as I'm exploring advanced API capabilities, techniques, and choices not only for GitHub API. So this won't be the last.
