I started to use isEven with the free tier about a year ago and never stopped since then. It does all the work to figure out if a number is even and allows me to focus on core development activities like new product research and design. I love it and recommend it to everyone.

Awesome features for the money. I never thought such a low amount of money would bring me so many answers per month. Before isEven I used a giant case expression and it was a mess. Highly recommended to programmers focused on results.

isEven is the best numerical API for small and medium sized business. It understands the mindset of young programmers and provides the necessary data for wise number-related decisions. Just give it a try and you will definitely not regret spending your time.

isEven is one of the greatest APIs out there. I especially love the number API route because it gives me such a great amount of information based on a little amount of input gathered in just few weeks of light weight usage. Recommended!
