ZipTax

Zip-Tax.com provides a very simple API for querying sales and use tax rates in most zip codes in the United States. This gem provides a thin wrapper around the API to quickly and easily retrieve sales tax rates by zip code.

Official documentation for the API is hosted by Zip-Tax.

You will need an API key to get started (sadly, no free developer accounts exist)

Installation

Add this line to your application's Gemfile:

gem 'ziptax', require: 'zip_tax'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ziptax

Usage

Try it out in irb:

gem install ziptax
irb -r ziptax
