AFAIK there are not any official Blizzard APIs for WC3 Reforged. However, it is my understanding both maps and replays are saved in S3.
I was wondering if opening up the listing to these replay / map folders would be possible?
I have put together a 3rd party API for getting data from WC3 replays so custom game communities can create stat tracking & ranking systems but it suffers greatly from “replay-holes”; games played where nobody uploaded a replay. There has been a fair amount of mapper / developer interest in the API since I started making it a year ago though the replay-hole concern is often cited.
If I don’t misunderstand how S3 is setup, I think this would be very beneficial. Would just need to make the listing public.
Happy to chat,
