XChange is a Java library providing a simple and consistent API for interacting with over a dozen Bitcoin exchanges providing a consistent interface for trading and accessing market data.
The world of Bitcoin changes quickly and XChange is no exception. The best way to stay updated on important announcements is to follow tweets on Xeiam's Twitter page. For the latest bugfixes and features you should use the [snapshot jars] (https://oss.sonatype.org/content/groups/public/com/xeiam/xchange/) or build yourself from the DEVELOP branch. See below for more details about building with Maven. To report bugs and see what issues people are currently working on see the issues page.
XChange is a library providing a simple and consistent API for interacting with a diverse set of financial security exchanges, including support for Bitcoin.
A complete list of implemented exchanges, data providers and brokers can be found on our Exchange Support page.
Usage is very simple: Create an Exchange instance, get the appropriate service, and request data.
// Use the factory to get the version 2 MtGox exchange API using default settings
Exchange mtGox = ExchangeFactory.INSTANCE.createExchange("com.xeiam.xchange.mtgox.v2.MtGoxExchange");
// Interested in the public polling market data feed (no authentication)
PollingMarketDataService marketDataService = mtGox.getPollingMarketDataService();
// Get the latest ticker data showing BTC to USD
Ticker ticker = marketDataService.getTicker(Currencies.BTC, Currencies.USD);
System.out.println(ticker.toString());
All exchange implementations expose the same API, but you can also directly access the raw data.
Now go ahead and study some more examples, download the thing and provide feedback.
- MIT license
- consistent API across all implemented exchanges
- active development
- very minimal 3rd party dependencies
- modular components
- polling and streaming capability
