** Installation

The library is available as a rubygem.

#+BEGIN_SRC sh gem install btce #+END_SRC

** Basic Usage

Populate the file =btce-api-key.yml= along the same lines as the example.

The only thing that 99% of the people using the library will want to do with it:

#+BEGIN_SRC ruby require 'btce' ticker = Btce::Ticker.new “btc_usd” #+END_SRC

This should return something resembling:

#+BEGIN_SRC ruby #<Btce::Ticker:0x00000000d5d9a0 @operation=“ticker”,



You can then acces the fields with the predefined methods of the =Ticker= class.

** =API= Class

This is the parent class for both the =PublicAPI= class and the =TradeAPI= class.


This is the domain of the server, defaulting to the string =btc-e.com=.


This is a list of the short strings for all of the currencies currently supported on [[href=“http://btc-e.com][btc-e.com]”>btc-e.com]].


This is a list of all of the supported currency pairs on [[href=“http://btc-e.com][btc-e.com]”>btc-e.com]].


This indicates how many digits past the decimal place are commonly displayed to humans for a given currency pair.
