From today there is problem with player API. It seems that incorrect players are returned for majority of calls. For example:
https://api.chess.com/pub/player/quokam - returns not quokam, but some player from Greece with name ceptiums
https://api.chess.com/pub/player/borkro - returns player "lepredaror"
etc.
and some works fine as:
https://api.chess.com/pub/player/bothbears
Topic to discuss identified bugs with the APIS.
