It seems patchy because I found this one that still works...
https://api.chess.com/pub/club/levice/members
but most others look broken?
These look ok...
- https://api.chess.com/pub/club/team-kyrgyzstan2/members
- https://api.chess.com/pub/club/the-gmbit-plyers/members
- https://api.chess.com/pub/club/ural/members
- https://api.chess.com/pub/club/ajedrez-de-las-espanas/members
but many others fail. There's no pattern I can see.
This API endpoint returns an error for most of the clubs I've tested:
{"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 ."}
Examples:
Actually so far I only got it working for this very club.
