This library provides Python bindings to the API offered by cryptsy.com.

Note: use at your own risk. This project is in alpha status and is not affiliated with cryptsy.com.

The only dependency is the very convenient Python library requests. To install:

pip install requests

git clone https://github.com/hsharrison/python-cryptsy.git
cd python-cryptsy
python setup.py install

Three APIs are offered. For the first two (public and private), functions/methods have the same names and signatures as described in the cryptsy API specs.

To access the public API methods:

import cryptsy.public

The public methods are implemented as module-level functions in cryptsy.public. Besides those in the API spec, there is one additional helper function:

id_to_pair, pair_to_id = cryptsy.public.get_market_ids()

This returns a mapping from pair strings to ids and vice-versa, allowing for easy conversion back and forth.

Note: As of the time of this writing, cryptsy's public API methods appear to be unreliable. The private methods can duplicate all their functions, so it is recommended to use those instead.

To access the private APIs:

from cryptsy.private import AuthenticatedSession

api = AuthenticatedSession('keyfile.txt')

where keyfile.txt has two lines: the first line containing your API key and the second your API secret. There is also an implementation of get_market_ids as a method of AuthenticatedSession.

Finally, I have implemented an API that mirrors as closely as possible the API of bter-api and by extension the original btce-api. It is nearly a drop-in replacement (but again, use at your own risk):

import cryptsy.bterapi as bterapi

api = bterapi.TradeAPI('keyfile.txt')

bterapi code is not prefectly compatible. Be aware of the following differences:

• Authenticate TradeAPI by passing the name of a key file instead of a KeyHandler instance.
• Currency pairs are split by / instead of _. That is, use LTC/BTC instead of LTC_BTC.
• bterapi.all_pairs is now api.all_pairs, where api is a TradeAPI instance.
• bterapi.fees could not be duplicated in the same way as the original, because cryptsy has different fees for buys and sells. Instead use api.calculatefees(order_type, quantity, price) to determine fees.
• Not all functions and methods have been duplicated. If one is missing, feel free to contribute!

Note: I recommend using this module only as a temporary measure. It would be beneficial to port your code to cryptsy.private as a long-term solution.

One final usage comment: any keyword arguments passed to any of the public methods, or used in the creation of an AuthenticatedSession will be passed onto the corresponding call to requests. Use a keyword argument to specify a timeout duration, for example:

api = bterapi.TradeAPI('keyfile.txt', timeout=1)
