Which is the right UUID in the 観戦 (Kansen) mode that I should crawl if I cannot use Amazon S3?

[FYNIXqwq]

I'm trying to write a simpler (in mechanism) UUID sniffer as it is tricky to register and use Amazon S3 in the place I live. None of them is the right ID in this link above, therefore how to get the UUID by just clicking Kansen games?

Another question is that in order to get large amount of data, simply clicking into a Kansen page, get requests and open another by Selenium is inefficient (plus there are only a few game records available in the Kansen lists that you have to refresh over time). Is there a better way to get data locally in a more efficient way?

My point is to crawl locally in a simpler way, thx if reply.
