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

Well then, I won’t be a paying customer then.

[−] Rendello 40d ago

I should mention that unicode.org has a "Unicode Set" query tool so no one gets swindled by a similar service ;)

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.

[−] OsrsNeedsf2P 41d ago

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

[−] 8n4vidtmkvmk 40d ago

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

[−] ollybee 40d ago

With 250k weekly downloads. That is no joke.

[−] stkdump 40d ago

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

[−] akoboldfrying 41d ago

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

[−] timcobb 41d ago

> 77.7% uptime SLA

looks like one 7

[−] pugworthy 41d ago

Seven Sigma is not all it's cut out to be.

[−] NooneAtAll3 41d ago

that's at least 3

[−] grant0417 41d ago

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

[−] Quot 41d ago

7.0000000000000001 evaluates to true.

[−] dudeinjapan 41d ago

It's an inclusive app.

[−] silisili 41d ago

As does 6.9999999999999999.

[−] geor9e 41d ago

true: 0x7, 007, 0b111

kinda: seven

false: siete, 111, VII

[−] encody 40d ago

> 77.7% uptime SLA

Giving GitHub a run for its money, I see.

[−] evanb 41d ago

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

[−] nvader 41d ago

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

This app is ngmi

[−] wincy 41d ago

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.

[−] akoboldfrying 41d ago

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

[−] kmoser 41d ago

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

[−] golem14 41d ago

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?

[−] addandsubtract 40d ago

I think everyone has moved on to iseight

[−] fosco 41d ago

00000111 also came back false

[−] downboots 41d ago

no Roman numeral support either

[−] charcircuit 41d ago

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

[−] CobrastanJorji 41d ago

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.

[−] 8n4vidtmkvmk 40d ago

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

[−] seanhunter 40d ago

7x7=49 > 45=5*9.

Ldo.

[−] qot 40d ago

Very similar to https://isevenapi.xyz/

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

[−] himata4113 41d ago

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

[−] LatticeAnimal 41d ago

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

[−] forthwall 41d ago

Needs an Agent skill! Gotta be more modern :)

[−] rushabh 41d ago

Reminds me of https://five.js.org/

[−] dustimpact 41d ago

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

[−] simeonmiteff 41d ago

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

[−] bombcar 41d ago

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

[−] rnoorda 41d ago

It's just as random as any other number!

[−] layer8 41d ago

It hallucinates 6.9999999999999996 to be seven.

[−] 0xblinq 41d ago

I wanted to subscribe and I can't! How do you expect to make any money if that doesn't work?!!1

[−] iamgopal 41d ago

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

But their feeling hurts, especially primes.

[−] csmantle 41d ago

This Is Seven as a Service.

[−] layer8 41d ago

No, this is the test harness for Seven as a Service.

[−] verzali 39d ago

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

[−] system2 41d ago

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

[−] amarant 41d ago

10? That seems about $3 too much!

[−] nwhnwh 41d ago

I will vibe code my way out of poverty:

[−] s20n 41d ago

Does this have an MCP server?

[−] darkhorse13 40d ago

Is this SOC2 compliant?

[−] matt3210 41d ago

Does not work for Nw==

[−] mwkaufma 41d ago

TIL 6+1 is not seven.

[−] seanhunter 40d ago

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.

Smh

[−] zetanor 40d ago

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

[−] cyanydeez 40d ago

needs an MCP.

[−] hyperhello 41d ago

Eh, more better than Prolog.
