That can occasionally happen. It will likely work after the next endpoint refresh.

The API is a super cool feature of chess.com and it's even more amazing that you guys make it free, so I know we really cannot complain, but I've been retrying the same endpoints for weeks. It has been in bugfix-mode for 8 months already x.x
Maybe an async pgn request system could be put in place, if momentarily? Lots of unnecessary requests are currently being made to the already crowded, traffic-intense website that is chess.com. I feel guilty for retrying so much
Sorry if this is the wrong place - I am trying to access an API and it is referring me to post about it here:
API GET: https://api.chess.com/pub/player/donotquestionauthority/games/2025/02
Result:
{"code":0,"message":"An internal error has occurred. Please contact Chess.com Developer's Forum for further help https://www.chess.com/club/chess-com-developer-community ."}
Other months work fine so far (2025/03, 04, etc), but I am trying to use automation to analyze my games and am concerned that they could break as well.
