How do I get sub directory of an web api

I want to create some statistics for the game auto chess and I know it has a API here: https://autochess.varena.com/api/autochess/match/1558139447625_2831/info?t=1558973553569 . This are stats of the result of one match. I would like to find out other links of this api for example the one that has match ids of newly played games but I dont know how to get those. Is there an way to get all sub directorys of an api?

for example I already tryed https://autochess.varena.com/api/autochess returns only an error.
