Crypto Facilities is a cryptcurrency derivatives exchange. This package is a Python client for the REST API of the exchange. This is similar to the official client (https://github.com/CryptoFacilities/REST-v2-Python) except that it implements V3 of the API rather than V2.
Disclaimer: I haven't used this too seriously yet "in production", but it does have extensive tests.
from crypto_facilities import APIKey, get_instruments, get_positions
# Unauthenticated access:
print(get_instruments())
# Authenticated methods require a key argument. You can generate one at
# https://www.cryptofacilities.com/derivatives/account#apiTab
key = APIKey('public', 'private')
print(get_positions(key))
API calls are limited to 1 call every 0.1 seconds per IP address. If this is exceeded you will start getting exceptions from the API, so if you are going to use the API heavily you might to implement your own rate limiting to keep below this threshold.
