Hello, and thank you so much, these are super helpful! I'm trying to make an !elo command that shows rapid, blitz and bullet ratings. I don't know anything about code, but using your !elo command I was able to almost make it work. This was my input
$(eval const api = $(urlfetch json https://api.chess.com/pub/player/$(query)/stats); "$(query) Rapid: "+ api[chess_rapid][last][rating] )$(eval const api = $(urlfetch json https://api.chess.com/pub/player/$(query)/stats); "$(query) Blitz: "+ api[chess_blitz][last][rating] )$(eval const api = $(urlfetch json https://api.chess.com/pub/player/$(query)/stats); "$(query) Bullet: "+ api[chess_bullet][last][rating] )
and this is the output
hikaru Rapid: 2769hikaru Blitz: 3241hikaru Bullet: 3282
Is there any way to remove the name, or have it only show up once before the ratings?

Tldr remove $(query) before blitz and bullet.

Longer answer $(query) is a variable which contains the input given to the command. In this case a chess.com user name. First, the script creates a new variable $(api). $(api) is filled with some data from chess.com based on the $(query) user id. This is just a simple page which contains a bunch of user data. You could even open it in a browser (https://api.chess.com/pub/player/hikaru/stats).

The script reads the right data from the website and prints it. Currenrly, you fetch the same data 3 times. You could rewrite the command to only get it once and read it 3 times.

Awesome! It works like a charm now. Thank you so much for this!
