Europeana API
Ruby client library for the search and retrieval of records from the Europeana REST APIs.

gem 'europeana-api'
And then execute:
bundle
Or install it yourself as:
gem install europeana-api
Usage
Authentication
Authentication by API key is required for all requests to the Europeana API.
Sign up for an API key at: https://pro.europeana.eu/get-api

end
