cryptologic

Python3 wrapper to query cryptocurrency prices (and more) using the CryptoCompare API.

Install

pip install cryptologic

Usage

import cryptologic

API Key

If you have an API key, you can either set it as environment variable CRYPTOCOMPARE_API_KEY or set it manually with:

cryptologic.cryptologic._set_api_key_parameter(KEY_HERE)

Coin List

cryptologic.coin_list(format=False)
# ...
# },
# 'BTC': {
#  'Id': '1182'
#  'Url': '/coins/btc/overview'
#  'ImageUrl': '/media/19633/btc.png'
#  'Name': 'BTC'
#  'CoinName': 'Bitcoin'
#  'FullName': 'Bitcoin (BTC)'
#  'Algorithm': 'SHA256'
#  'ProofType': 'PoW'
#  'FullyPremined': '0'
#  'TotalCoinSupply': '21000000'
#  'PreMinedValue': 'N/A'
#  'TotalCoinsFreeFloat': 'N/A'
#  'SortOrder': '1'
# },
# ...

If format is True, the coin list is returned as Python list, containing only the abbreviations (like BTC).

Price

cryptologic.get_price('BTC')
# or
cryptologic.get_price('BTC', currency='USD', full=True)
# or
cryptologic.get_price(['BTC', 'ETH'], ['EUR', 'GBP'])

# {'BTC': {'EUR': 3709.04, 'GBP': 3354.78},
#  'ETH': {'EUR': 258.1, 'GBP': 241.25}}

Historical Prices

# pass either datetime or time instance
cryptologic.price('XMR', timestamp=datetime.datetime(2017,6,6), exchange='CCCAGG')
# or
cryptologic.price('XMR', 'EUR', datetime.datetime(2017,6,6))

# {'XMR': {'EUR': 43.05}}

Day

cryptologic.price_day('BTC', currency='EUR')
cryptologic.price_day('BTC', currency='EUR', limit=30)
cryptologic.price_day('BTC', 'EUR', limit=24, exchange='CCCAGG', toTs=datetime.datetime(2019,6,6))
# or
cryptologic.price_day('BTC', 'EUR', limit=24, exchange='CCCAGG', toTs=datetime.datetime(1559815200))

Hour

cryptologic.price_hour('BTC', currency='USD')
cryptologic.price_hour('BTC', currency='EUR', limit=24)

cryptologic.price_hour('BTC', 'EUR', limit=24, exchange='CCCAGG', toTs=datetime.datetime(2019,6,6,12))
# or
cryptologic.price_hour('BTC', 'EUR', limit=24, exchange='CCCAGG', toTs=datetime.datetime(1559815200))

Exchanges

cryptologic.get_exchanges()

Pairs

cryptologic.get_pairs()
pairs = cryptologic.get_pairs(exchange='Kraken')

Developing

Tests run assuming you have an API key, otherwise they will error due to rate limiting. Install the dev dependencies and run the tests:

pip3 install -r requirements.txt
python3 -m pytest
