Build an AI chess player that takes input from a website

I would like to make a program that would be able to take input from chess.com and chess24.com and be able to play at different speeds and levels for example i could set the AI to play at a 3200 rating and play very fast like blitz chess which usually takes around 2-5 sec per move. or i could adjust the bot to play at a 1300 rating but very slow and vice versa.

Main Features
AI Rating/Skill adjuster
Speed Adjuster

Optional Features
possibility to make Human like errors
log in to accounts and keep a list of accounts to be able to login easier
ratings for each account
