DEPRECATED: Amazon Web Services Pricing Ruby Gem


This project is no longer being maintained and will be deprecated in the future. Issues and pull requests will no longer be accepted. If you have scripts that utilize this project, consider using alternate libraries.

Amazon has updated the method it uses to provide pricing information to be an API; as such the methods contained within this Gem are no longer useful for obtaining pricing information.

Updates to the gem will be few and far between; please contact [email protected] with any questions.

Information on Amazon's pricing api is available here:

About amazon-pricing

Amazon Web Services offers cloud-based on demand compute, storage and application services. Due to the number of services, and the number of pricing variables in each service, the pricing model is very complex. In addition, this pricing changes periodically. The amazon-pricing Ruby Gem is an interface library that simplifies the real-time retrieval of pricing information from Amazon.

This gem follows the standard conventions for installation on any system with Ruby and RubyGems installed and uses Bundler for gem installation and build management.

Using amazon-pricing

The library exposes one main interface class AwsPricing::PriceList that allows you to retrieve pricing information from Amazon. The information is retrieved using undocumented json APIs - so has the potential to undergo change from time to time.
