Installation

The library is available as a rubygem.

gem install btce

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:

require 'btce'
ticker = Btce::Ticker.new "btc_usd"

This should return something resembling:

#<Btce::Ticker:0x00000000d5d9a0 @operation="ticker",
                                @pair="btc_usd",
                                @json={"ticker"=>{"high"=>127,
                                                  "low"=>87.301,
                                                  "avg"=>107.1505,
                                                  "vol"=>4240695.81634,
                                                  "vol_cur"=>39298.55663,
                                                  "last"=>115,
                                                  "buy"=>115,
                                                  "sell"=>114.499,
                                                  "server_time"=>1366406293}}>

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