Is it possible to check previous seasons'...

[quote=Ekki]I've noticed op.gg does show previous seasons rankings, and it made me wonder, does the Riot API allow to check previous seasons' standings? Is there another way to check it? I'm asking mostly for award swag (if it is possible, could you retroactively add the proper awards to verified accounts?), but also to know if it's possible to check it somehow.[/quote]

[quote=PsiGuard]I'm sure I could just check the individual's op.gg page to see their final ranks from last season and add the badges manually, but I don't know if it's possible to find out peak rank from a past season.[/quote]

[quote=Ekki]Don't bother yourself with it if the only way to do it is manually though. I was asking in case there was an automated way (my example was via de Riot API but IDK if there is an alternative to it).[/quote]
