I'm glad to see https://isevenapi.xyz/ made the list.

I love their pricing options include larger ranges of numbers, and enterprise class also includes negative numbers. ha ha.

Best part is that 'sign up' links to https://archive.org/donate/

[darknavi]

I think their ad placement is even better than their pricing.

API Result:

GET https://api.isevenapi.xyz/api/iseven/6/

{"ad":"Buy isEvenCoin, the hottest new cryptocurrency!","iseven":true}

What I really want is isoddapi.xyz.

Just like the npm package, all it should do is call isevenapi.xyz and invert the result.

I'd like to see isfizzbuzz.xyz.

Ideally, before 11:30 AM ET this Friday.

Putting the 'micro' into microservices one bit of logic at-a-time :)

[drexlspivey]

And then isevenapi.xyz should call isoddapi.xyz and invert the result to offload all the work to them.

[Medox]

isprimeapi.xyz would be helpful.

[yakshaving_jgt]

I hope someone sets up isthirteenapi.xyz.

[giarc]

I Seven API vs is Even API. Can't say I saw it the right way at first.

[fragmede]

that makes me want to make an is seven API.

[Lerc]

I feel like one of the categories they are missing is 'APIs that can be done in one line of JavaScript"

I'm not saying these shouldn't exist, I think they're pretty funny, but everything in its place.

[dhosek]

These come in handy in an instructional context—being able to have a simple predictable API that you can point students at so they can learn how to call an API and process its data.

This made my day..

But what do I do if I need to know if a number is odd?

[zamadatix]

Launch a startup!

> If a number isn't even, you can easily tell that it's odd.

[ramon156]

Yeah that's a hole in the market, I'm stealing it

[zenoprax]

It was the first one I searched for. What a silly tool: Parity as a Service.
