Ruby wrapper for currencylayer of apilayer. See currencylayer.com/ and apilayer.com for more details.
Introduction¶ ↑
This gem is extracted from the previous version of apilayer gem.
While the currency_layer gem focuses on the functionalities offered by currencylayer, it depends on the apilayer gem to configure and create connections to apilayer.net
Installation¶ ↑
Using Bundler¶ ↑
Add apilayer in your Gemfile
:
gem "currency_layer"
Run the following in your console:
$ bundle install
Usage¶ ↑
Add to your application¶ ↑
require "currency_layer"
Set up currency_layer¶ ↑
Once you have signed up for currencylayer.com, you will receive an access_key. Then configure your Apilayer::Currency module like this:
Apilayer::Currency.configure do |configs| configs.access_key = "my_access_key_123" configs.https = true end
Please note that the https configuration is optional and only available to paid-accounts. If unset, these configuration-values are just nil.
You can always review you configurations with:
Apilayer::Currency.configs
Once your configurations are set, you are ready to go

After setting the access_key for currencylayer, you can use Apilayer::Currency to call currencylayer’s API
Apilayer::Currency.list Apilayer::Currency.live Apilayer::Currency.live(:currencies => %w[GBP, CHF]) Apilayer::Currency.live(:source => "EUR") # source-currency is USD by default Apilayer::Currency.live(:source => "EUR", :currencies => %w[GBP, CHF]) Apilayer::Currency.historical("2016-01-01") Apilayer::Currency.historical("2016-01-01", :currencies => %w[GBP CHF]) Apilayer::Currency.historical(:source => "EUR") # source-currency is USD by default Apilayer::Currency.historical("2016-01-01", :currencies => %w[GBP CHF], :source => "EUR") Apilayer::Currency.convert("EUR", "CHF", 100) # convert 100 EUR to CHF Apilayer::Currency.convert("EUR", "CHF", 100, "2015-06-01") # based on specific date Apilayer::Currency.timeframe("2016-01-01", "2016-06-01") Apilayer::Currency.timeframe("2016-01-01", "2016-06-01", :currencies => %w[GBP CHF]) Apilayer::Currency.timeframe("2016-01-01", "2016-06-01", :source => "EUR") Apilayer::Currency.timeframe("2016-01-01", "2016-06-01", :currencies => %w[GBP CHF], :source => "EUR") Apilayer::Currency.change Apilayer::Currency.change("2016-01-01", "2016-03-01") Apilayer::Currency.change("2016-01-01", "2016-03-01", :source => "EUR") Apilayer::Currency.change("2016-01-01", "2016-03-01", :currencies => %w[GBP CHF]) Apilayer::Currency.change("2016-01-01", "2016-03-01", :source => "EUR", :currencies => %w[GBP CHF]) Apilayer::Currency.change(nil, nil, {:source => "EUR"}) Apilayer::Currency.change(nil, nil, {:currencies => %w[GBP CHF]}) Apilayer::Currency.change(nil, nil, {:source => "EUR", :currencies => %w[GBP CHF]})

If you happened to have forgotten to set or entered an incorrect value, you can re-configure your Apilayer module by:
# Example: reconfigure https Apilayer::Currency.configure do |configs| configs.https = true end
