It is simple chess API for bots, which is based on chess library. It provides small functionality, although it is enough to build your own bot from scratch.

>>> import chessbots
>>> import chessbots.bot
>>> import chessbots.engine
>>> chessbots.bot.BaseBot() # The class which contans basic functions for your bot
>>> chessbots.bot.ExampleBot() # Built-in bot based on minimax algorithm
>>> chessbots.engine.LaunchGame(bot1, bot2) # Function which allows bots to play games against each other
