PaapiMini

This is a Gem for easy Amazon product search.
Before using it, you need to pass Amazon Associate review and get ACCESS_KEY etc. as preparation.
Amazon Product Advertising API 5.0　is supported.
This Gem is implemented using only the Ruby standard-attached library, so it does not depend on other Gems.

Ruby versions that have been tested by rbenv

ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-darwin20]
ruby 3.0.0rc1 (2020-12-20 master 8680ae9cbd) [x86_64-darwin20]
ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-darwin21]

We have not tested Ruby for Windows at this time.
Also, since the author's Amazon Associate review is conducted by Amazon.co.jp, we are only able to test from this region.
Therefore, the default behavior of the API is Amazon.co.jp. It is possible to change it with an argument.
We would appreciate it if you could provide us with feedback if you can confirm that it works on the Windows version or in regions other than Amazon.co.jp.
