'Does this endpoint belong to the Steam Web API?

I've been looking for a way to get in-game information from the game Dead by Daylight, such as Characters, Perks, Items, etc. In my search, I found an old GitHub Repository, from which I was able to get a link to return a list of all the outfits from the in-game store:

https://steam.live.bhvrdbd.com/api/v1/extensions/store/getOutfits

You have to anonymously login through https://steam.live.bhvrdbd.com/api/v1/auth/login/guest first to get a token... I think. It worked that way for me on Postman.

What I'm confused about is what this endpoint even is. Steam Web API endpoints usually start like this:

https://api.steampowered.com/

So what is this seemingly DbD-specific API endpoint? Is it part of the Steam Web API? Or is this something different from before Steam Web API was even a thing or widely available to most developers? The game did come out in 2016 after all.

What is this endpoint and where can I find documentation about it?
