Basic attempt at using Best Buy's API.

best-buy.rb

require 'faraday'
require 'json'

class BestBuy
  API_KEY = 'APIKEYHERE' # get one at developer.bestbuy.com
  
  # initializes faraday and adds API key to options hash
  def initialize
    @options = { apiKey: API_KEY }
    
    @conn = Faraday.new(url: 'http://api.remix.bestbuy.com') do |f|
      f.request :url_encoded
      f.response :logger
      f.adapter :excon
    end
  end
  
  # returns response (as a hash) of product listing
  def product(sku)
    response = @conn.get "/v1/products/#{sku}.json", @options
    JSON.parse response.body
  end
end
