Python library that aims to provide a uniform access layer for cryptocurrency exchanges. Currently, the library supports access to Cryptsy and to BTC-e.
pip install git+https://github.com/coink/cryptex.git
All methods are performed by first initializing an Exchange with your API key
and secret.
>>> from cryptex.exchange import Cryptsy
>>> exchange = Cryptsy('API_KEY_HERE', 'API_SECRET_HERE')Currently, the only exchanges are cryptex.exchange.Cryptsy and
cryptex.exchange.BTCE.
>>> exchange.get_markets()

in UTC. Prices and amounts are represented as decimal.Decimals, never
floats. Trade.trade_type must be either Trade.BUY or Trade.SELL.

>>> exchange.buy(market, amount, price)

>>> exchange.sell(market, amount, price)
13424The buy and sell methods both return the order_id of the created order.
