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.

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

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

7.0000000000000001 evaluates to true.

> 77.7% uptime SLA

Giving GitHub a run for its money, I see.

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

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

This app is ngmi

Very similar to https://isevenapi.xyz/

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

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.

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

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

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

Needs an Agent skill! Gotta be more modern :)

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

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

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

It hallucinates 6.9999999999999996 to be seven.

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

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

But their feeling hurts, especially primes.

This Is Seven as a Service.

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

Does this have an MCP server?

Is this SOC2 compliant?

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

Does not work for Nw==

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.

I will vibe code my way out of poverty:

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

needs an MCP.

Eh, more better than Prolog.
