Render - Service to Make Free APIs?

Link: https://render.com/pricing

A service I found about during the Hombrew Clug Europe meeting. I am wondering, if their free services could be used to create some simple APIs, that I would be using.

I wonder if GitHub has a API to create new commits. Because then it would be possible to create a sort of interface to create new posts for me. Another example would be for me to do sort of PESOS from AO3 or meetups. It would have to be sort of manual, since AO3 does not really have any place to see the list of all the comments, that I have made. Maybe meetup does have something like that? That way, I would not have to manually add the posts each time.
