Lichess API

Hi. Could anyone be so kind to advise how to get Fide rating from profile and highest/lowest ratings per variant without analysis of all available data?
Maybe i miss smth but i couldnt find them from any available api.
Thanks in advance.

You cannot get FIDE rating from every profile since they are not required. Also, some people put a fake rating(such as 3000) just for laughs. Hope this helps.

@ChesswurmOTB yes i agree. But there might be an optional parameter i guess. Or ask for fide id to prove it, even hidden private one.
BTW, what about peak ratings per variant?

You can use lichess.org/api#operation/apiUser to get FIDE rating, but, as it has been already mentioned, there is no guarantee it is real.
I don't think you can get absolute min/max rating using the API. You can, however, extrapolate min/max using lichess.org/api#operation/apiUserRatingHistory

@bufferunderrun thanks. Will check it

@bufferunderrun apiUser is not getting fide rating neither directly in tree nor in profile subtree, it is not specified there as well.

Regarding extrapolating, yes it is possible. It is possible to get full history and found it. But is it a proper way? I dont think lichess do it each time when user visit someone's variant page. I'd believe there is some field in db which can be easily retrieved
