• Check whether a number is evenAsk isEven whether one whole number is even or odd, and get a yes or no to branch on, the verdict as a word, and the spoof classified ad isEven attaches to every answer. The free public tier covers 0 to 999,999. No account or API key required.
• Check several numbersAsk isEven about up to 25 whole numbers in one step and get a verdict for each, in the order given, with the even and the odd ones listed and counted. isEven answers one number at a time, so each different number is one request; a repeated number is asked about once.
