Provides a simple, uniform method for accessing public ticker APIs for various online crypto-currency (e.g. Bitcoin, Litecoin) exchanges (e.g. Bitstamp, BTC-e, etc.).

I don't use this and don't recommend it. 'Twas made when I started learning Ruby, but doesn't offer any significant functionality.

gem install crypto_ticker

The ticker functions (btcusd, ltcusd, etc) return an HTTParty::Response, and this module includes a parser for the body. The parser returns numeric data as BigDecimal values, which can be manipulated however you like. Hash keys differ for each exchange, but :high, :low, and :last should always exist in the response.

require 'crypto_ticker'

# get spot BTC/USD price from BTC-e exchange:
h = CryptoTicker::BTCe.btcusd.parsed_response

puts <<-EOF
BTC/USD stats:

       high: #{h[:high].to_f}
        low: #{h[:low].to_f}
        avg: #{h[:avg].to_f}
        vol: #{h[:vol].to_f}
    vol_cur: #{h[:vol_cur].to_f}
       last: #{h[:last].to_f}
        buy: #{h[:buy].to_f}
       sell: #{h[:sell].to_f}
    updated: #{h[:updated].to_f}
server_time: #{h[:server_time]}
EOF
