    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.

    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.

    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.

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

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

      I think that's part of the joke. iseven is a real, non-joke package.
      • ollybee 3 hours ago
        With 250k weekly downloads. That is no joke.

    7.0000000000000001 evaluates to true.
    • silisili 8 hours ago
      As does 6.9999999999999999.
      • geor9e 7 hours ago
        true: 0x7, 007, 0b111

        kinda: seven

        false: siete, 111, VII

      It's an inclusive app.
  • evanb 6 hours ago
    Bug report: I tried 6.999999̅ and got false. So there's some nonstandard model of the reals being leveraged here.

    > 77.7% uptime SLA

    Giving GitHub a run for its money, I see.

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

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

    This app is ngmi

      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.
    • kmoser 7 hours ago
      I would have expected something other than false for "se7en".
    • golem14 8 hours 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?

    • fosco 5 hours ago
      00000111 also came back false

      no Roman numeral support either

      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
  • himata4113 6 hours ago
    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?

    Enterprise looks promising, but before I take this to upper management: How many sevens of uptime are we talking?
    • timcobb 6 hours ago
      > 77.7% uptime SLA

      looks like one 7

        Seven Sigma is not all it's cut out to be.
      • NooneAtAll3 6 hours ago
        that's at least 3

    Needs an Agent skill! Gotta be more modern :)
  • dustimpact 6 hours ago
    Apparently “seven” is only kinda seven. I would argue that seven is seven!
    • simeonmiteff 6 hours ago
      Got to love that "kinda" is now a JSON bool value!
  • bombcar 7 hours ago
    I can use this as a random number generator; at least it's not nine.
    • rnoorda 5 hours ago
      It's just as random as any other number!

    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
  • iamgopal 5 hours ago
    No other numbers were harmed in the making of this API.

    But their feeling hurts, especially primes.

    This Is Seven as a Service.

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

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

    Is this SOC2 compliant?
  • seanhunter 2 hours 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

    Eh, more better than Prolog.
