Bit is Python’s fastest Bitcoin library and was designed from the beginning to feel intuitive, be effortless to use, and have readable source code. It is heavily inspired by Requests and Keras.

Bit is so easy to use, in fact, you can do this:

>>> from bit import Key
>>>
>>> my_key = Key(...)
>>> my_key.get_balance('usd')
'12.51'
>>>
>>> # Let's donate!
>>> outputs = [
>>>     # Wikileaks
>>>     ('1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v', 0.0035, 'btc'),
>>>     # Internet Archive
>>>     ('1Archive1n2C579dMsAu3iC6tWzuQJz8dN', 190, 'jpy'),
>>>     # The Pirate Bay
>>>     ('129TQVAroeehD9fZpzK51NdZGQT4TqifbG', 3, 'eur'),
>>>     # xkcd
>>>     ('14Tr4HaKkKuC1Lmpr2YMAuYVZRWqAdRTcr', 2.5, 'cad')
>>> ]
>>>
>>> my_key.send(outputs)

Dev Guide

Up ahead is Bit’s API and a few notes about design decisions. Beware the pedantry, or lack thereof.

Well done! There will be more soon, but right now you have nothing left to see. Remember, a watched pot never boils.
