Cryptoexchange asynchronous python client
cryptoxlib-aio is a compact Python library providing access to REST and WEBSOCKET API of selected crypto exchanges.
cryptoxlib-aio is designed as an asynchronous library utilizing modern features of Python and those of supporting asynchronous libraries (mainly aiohttp).
Today there are numerous existing libraries targeting similar audience as
cryptoxlib-aio. In order to achieve the broadest coverage of exchanges the supported API is often limited, the most apparent example being lack of websockets.
The mission of
cryptoxlib-aio is to:
- serve as a single entry point for various crypto exchanges
- provide full REST API as well as full implementation of exchange's websockets. For free and without subscription plans.
Full support of websockets is the corner stone of
cryptoxlib-aio which attempts to set
cryptoxlib-aio apart from existing solutions which either do not provide websocket support or do not provide it for free.
You will also find out that our subject of interest are often exchanges not enjoying a seat in the mainstream crypto libraries and this is a way for them to reach developers community.
Disclaimer: By no means we are suggesting that existing libraries are inferior to
cryptoxlib-aio, they just appeal to different endusers.
- access to REST API as well as full support of websockets for selected exchanges (given websockets are provided by the exchange)
- automatic connection management (reconnecting after remote termination, ...)
- bundling of channels
- lean architecture making it straightforward to implement API of a new exchange
- fully asynchronous design aiming for the best performance
For the history of changes see CHANGELOG.
List of supported exchanges
As mentioned earlier, all exchanges listed below include full support for websockets.
Unlike REST API which is rather uniform across crypto exchanges websockets are often very exchange-specific and hence very time consuming to implement (which is the reason why they are not offered so broadly). Therefore
cryptoxlib-aio comes at the cost of the number of exchanges it covers. This is in line with our ideology quality over quantity.
The list of supported exchanges will grow without any specific pattern, usually driven by personal needs. If there is a high demand for a new exchange/feature to be added, there is a high chance for it to happen (but not guranteed).

pip install cryptoxlib-aio
In case you want to install the latest version from the repo, use
pip install git+https://github.com/nardew/cryptoxlib-aio.git@master
bitpanda = CryptoXLib.create_bitpanda_client(api_key) print("Account balance:") await bitpanda.get_account_balances() print("Order book:") await bitpanda.get_order_book(Pair("BTC", "EUR")) print("Create limit order:") await bitpanda.create_limit_order(Pair("BTC", "EUR"), OrderSide.BUY, "10000", "1") # Create first bundle of subscriptions bitpanda.compose_subscriptions([ AccountSubscription(), PricesSubscription([Pair("BTC", "EUR")]), OrderbookSubscription([Pair("BTC", "EUR")], "50", callbacks = [order_book_update]), CandlesticksSubscription([CandlesticksSubscriptionParams(Pair("BTC", "EUR"), TimeUnit.MINUTES, 1)]), MarketTickerSubscription([Pair("BTC", "EUR")]) ]) # Bundle another subscriptions into a separate websocket bitpanda.compose_subscriptions([ OrderbookSubscription([Pair("ETH", "EUR")], "3", callbacks = [order_book_update]), ]) # Execute all websockets asynchronously await bitpanda.start_websockets()
bitforex = CryptoXLib.create_bitforex_client(api_key, sec_key) print("Order book:") await bitforex.get_order_book(pair = Pair('ETH', 'BTC'), depth = "1") print("Create order:") await bitforex.create_order(Pair("ETH", "BTC"), side = enums.OrderSide.SELL, quantity = "1", price = "1") # First bundle of subscriptions bitforex.compose_subscriptions([ OrderBookSubscription(pair = Pair('ETH', 'BTC'), depth = "0", callbacks = [order_book_update]), TradeSubscription(pair = Pair('ETH', 'BTC'), size = "2", callbacks = [trade_update]), ]) # Another bundle of subscriptions bitforex.compose_subscriptions([ TickerSubscription(pair = Pair('BTC', 'USDT'), size = "2", interval = enums.CandelstickInterval.I_1MIN, callbacks = [ticker_update]), Ticker24hSubscription(pair = Pair('BTC', 'USDT'), callbacks = [ticker24_update]) ]) # Execute all websockets asynchronously await bitforex.start_websockets()
