Doesn't work for the other 125 encoded characters that are numerically seven, as defined in the Unicode Character Database:

I was almost sure that they do it client-side for a joke, but if you check the browser console, you can see that they actually make a request! You can even make the same request with curl and it works!

Although, making an HTTP request manually is quite inconvenient, so I'm waiting for Python SDK.

Heads up OP: I’m trying to get a pro license but your checkout flow is borked. Probably should fix ASAP before missing out on HN front page traffic.

Enterprise looks promising, but before I take this to upper management: How many sevens of uptime are we talking?

by akoboldfrying

4/5/2026 at 3:41:44 AM

> 77.7% uptime SLA

looks like one 7

Vulnerable to a distillation attack, unfortunately not much of a moat.

I misread this as "is even" and was shocked that 46 returned false

by OsrsNeedsf2P

4/5/2026 at 6:33:08 AM

I think that's part of the joke. iseven is a real, non-joke package.

by 8n4vidtmkvmk

4/5/2026 at 7:12:11 AM

With 250k weekly downloads. That is no joke.

With a dependency on is-odd (which in turn has a dependency on is-number)

7.0000000000000001 evaluates to true.

It's an inclusive app.

by silisili

4/5/2026 at 3:00:17 AM

true: 0x7, 007, 0b111

kinda: seven

false: siete, 111, VII

Giving GitHub a run for its money, I see.

by encody

4/5/2026 at 4:01:49 AM

Bug report: I tried 6.999999̅ and got false. So there's some nonstandard model of the reals being leveraged here.

by evanb

4/5/2026 at 2:07:21 AM

Bug report: I entered 3 + 4 and did not get a kinda or true.

This app is ngmi

by nvader

4/5/2026 at 5:02:30 AM

Well the all only has 77.7% uptime maybe it just returns wrong things while it’s down, that’s probably it. Try upgrading to Enterprise that’ll probably fix it.

by wincy

4/5/2026 at 2:22:16 AM

BTW: For a tool that actually legitimately does this, look at Semgrep. Their playground example literally assigns 1 to a variable x, after which searching for "2" finds the expression "1 + x" in the code: https://semgrep.dev/playground/s/5rKgj

by akoboldfrying

4/5/2026 at 3:09:03 AM

I would have expected something other than false for "se7en".

by kmoser

4/5/2026 at 2:18:21 AM

Similar report here:

70/10, 7.1-0.1 and srqt(49) also do not return true.

Is there a published SLA for the free version?

00000111 also came back false

by fosco

4/5/2026 at 2:24:16 AM

no Roman numeral support either

by downboots

4/5/2026 at 3:32:11 PM

Very similar to https://isevenapi.xyz/

Even down to injecting an ad into the response as a joke.

by qot

4/5/2026 at 4:18:28 AM

That documentation is woefully inadequate. It provides only one example request, and then it shows two separate responses, and it doesn't make clear which one is associated with the request. It doesn't even describe the individual request fields, nor does it provide any response codes or a list of error codes/messages. How am I supposed to develop with this?

I do, however, appreciate the seven figure SLA. My service requires at least five nines of uptime, and seven figures is definitely more than five.

by CobrastanJorji

4/5/2026 at 6:35:16 AM

Seven figures is indeed more than five figures. Too bad they're all 7s.

by 8n4vidtmkvmk

4/5/2026 at 8:25:40 AM

7x7=49 > 45=5*9.

Ldo.

This SaaS actually will be replaced with an in house vibecoded solution.

by charcircuit

4/5/2026 at 4:27:16 AM

complaint: someone entered "seven" and it crashed my entire infrastructure because the output returned a non standard 'kinda'.

JSONQ supports quantum-aware booleans. Is there a reason you’re still using classical JSON parsing in 2026?

by LatticeAnimal

4/5/2026 at 2:02:03 AM

Needs an Agent skill! Gotta be more modern :)

by forthwall

4/5/2026 at 3:52:19 AM

Apparently “seven” is only kinda seven. I would argue that seven is seven!

by dustimpact

4/5/2026 at 3:59:48 AM

Got to love that "kinda" is now a JSON bool value!

by simeonmiteff

4/5/2026 at 3:24:37 AM

I can use this as a random number generator; at least it's not nine.

by bombcar

4/5/2026 at 4:57:41 AM

It's just as random as any other number!

by rnoorda

4/6/2026 at 7:19:58 AM

Did not work, did not recognise 'VII' as seven.

by verzali

4/5/2026 at 4:29:10 AM

It hallucinates 6.9999999999999996 to be seven.

No other numbers were harmed in the making of this API.

But their feeling hurts, especially primes.

I like how you spent $10 for the domain for this. :)

by system2

4/5/2026 at 3:01:23 AM

10? That seems about $3 too much!

by amarant

4/5/2026 at 10:01:13 PM

The cheapest domain purchase can be made from CloudFlare. They are selling at ICANN's minimum fee. Which is $10...

by matt3210

4/5/2026 at 8:23:20 AM

We wanted to subscribe to the enterprise plan, but unfortunately:

- No Soc-2 compliance

- No sso support.

We asked if we could host on-prem or even byoc but that seems an impossible dream.

TIL 6+1 is not seven.

Oh, come on people. You don't need a cloud service for this. Just use the is-seven NPM package.
