Bitcoin Price API

If you are trying to do interesting things with bitcoin price data, you shouldn't have to be concerned with the low-level details of how to obtain that data, or the particular JSON structures that it comes in. This module will provide a unified way of getting price data from various exchanges which have publicly available API's, as well as a unified representation of that data rather than exchange specific ones.

Quick Guide

    >>> from exchanges.bitfinex import Bitfinex
    >>> Bitfinex().get_current_price()
    Decimal('371.17')

Dependencies

The only dependency is on the requests library. You can either do pip install requests or pip install -r requirements.txt inside the directory.

Bitstamp, Bitfinex, OKCoin, Huobi, and Coinapult

All of these classes expose the interface below:

get_current_price()
get_current_bid()
get_current_ask()

which will return a Decimal object. Note that all exchanges return values in USD, with the exception of Huobi which returns CNY.

Coinapult is special in that you can specify the currency for the above three methods.

get_current_price(currency='EUR')

Coindesk

The Coindesk class offers a much richer price interface:

get_current_price(currency='USD')
get_past_price(date)
get_historical_data_as_dict(start='2013-09-01', end=None)
get_historical_data_as_list(start='2013-09-01', end=None)

get_current_price and get_past_price both return Decimal objects.

get_current_price takes in an optional parameter specifying the currency.

The dates for all functions must be in the form 'YYYY-MM-DD'.

get_historical_data_as_dict will return a dictionary of the following format:

{'2014-10-20': 400.00, '2014-10-21': 301.99}

Remember that these date/prices will not be in any given order.

get_historical_data_as_list will return a list of dictionaries, correctly sorted by date from start to end.

[
    {'date': 'YYYY-MM-DD', 'price': 300.00},
    {'date': 'YYYY-MM-DD', 'price': 301.00 }
]
