    Doesn&#x27;t work for the <i>other</i> 125 encoded characters that are numerically seven, as defined in the Unicode Character Database:<p><a href="https:&#x2F;&#x2F;www.unicode.org&#x2F;Public&#x2F;17.0.0&#x2F;ucd&#x2F;extracted&#x2F;DerivedNumericValues.txt#:~:text=DIGIT%20SEVEN" rel="nofollow">https:&#x2F;&#x2F;www.unicode.org&#x2F;Public&#x2F;17.0.0&#x2F;ucd&#x2F;extracted&#x2F;DerivedN...</a><p>(Viewable &#x2F; copy-able version: <a href="https:&#x2F;&#x2F;pastebin.com&#x2F;fNRv3wD6" rel="nofollow">https:&#x2F;&#x2F;pastebin.com&#x2F;fNRv3wD6</a>)

      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!<p>Although, making an HTTP request manually is quite inconvenient, so I&#x27;m waiting for Python SDK.

    Vulnerable to a distillation attack, unfortunately not much of a moat.
  • OsrsNeedsf2P6 hours ago
    I misread this as &quot;is even&quot; and was shocked that 46 returned false
    • 8n4vidtmkvmk4 hours ago
      I think that&#x27;s part of the joke. iseven is a real, non-joke package.
      • ollybee3 hours ago
        With 250k weekly downloads. That is no joke.

    7.0000000000000001 evaluates to true.
    • silisili8 hours ago
      As does 6.9999999999999999.
      • geor9e7 hours ago
        true: 0x7, 007, 0b111<p>kinda: seven<p>false: siete, 111, VII
    • dudeinjapan5 hours ago
      It&#x27;s an inclusive app.
  • evanb6 hours ago
    Bug report: I tried 6.999999̅ and got false. So there&#x27;s some nonstandard model of the reals being leveraged here.

    &gt; 77.7% uptime SLA<p>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&#x27;t make clear which one is associated with the request. It doesn&#x27;t even describe the individual request fields, nor does it provide any response codes or a list of error codes&#x2F;messages. How am I supposed to develop with this?<p>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.
    • 8n4vidtmkvmk4 hours ago
      Seven figures is indeed more than five figures. Too bad they&#x27;re all 7s.

    Bug report: I entered 3 + 4 and did not get a kinda or true.<p>This app is ngmi
    • wincy5 hours 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.
    • kmoser7 hours ago
      I would have expected something other than false for &quot;se7en&quot;.
    • golem148 hours ago
      Similar report here:<p>70&#x2F;10, 7.1-0.1 and srqt(49) also do not return true.<p>Is there a published SLA for the free version?
    • fosco5 hours ago
      00000111 also came back false
    • downboots8 hours ago
      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 &quot;2&quot; finds the expression &quot;1 + x&quot; in the code: <a href="https:&#x2F;&#x2F;semgrep.dev&#x2F;playground&#x2F;s&#x2F;5rKgj" rel="nofollow">https:&#x2F;&#x2F;semgrep.dev&#x2F;playground&#x2F;s&#x2F;5rKgj</a>

    complaint: someone entered &quot;seven&quot; and it crashed my entire infrastructure because the output returned a non standard &#x27;kinda&#x27;.

      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?
    • timcobb6 hours ago
      &gt; 77.7% uptime SLA<p>looks like one 7

        Seven Sigma is not all it&#x27;s cut out to be.
      • NooneAtAll36 hours ago
        that&#x27;s at least 3

    Needs an Agent skill! Gotta be more modern :)
  • dustimpact6 hours ago
    Apparently “seven” is only kinda seven. I would argue that seven is seven!
    • simeonmiteff6 hours ago
      Got to love that &quot;kinda&quot; is now a JSON bool value!
  • bombcar7 hours ago
    I can use this as a random number generator; at least it&#x27;s not nine.
    • rnoorda5 hours ago
      It&#x27;s just as random as any other number!
  • layer86 hours ago
    It hallucinates 6.9999999999999996 to be seven.
  • 0xblinq5 hours ago
    I wanted to subscribe and I can&#x27;t! How do you expect to make any money if that doesn&#x27;t work?!!1
  • iamgopal6 hours ago
    No other numbers were harmed in the making of this API.<p>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?
  • seanhunter2 hours ago
    We wanted to subscribe to the enterprise plan, but unfortunately:<p>- No Soc-2 compliance<p>- No sso support.<p>We asked if we could host on-prem or even byoc but that seems an impossible dream.<p>Smh

    TIL 6+1 is not seven.

    I like how you spent $10 for the domain for this. :)
    • amarant7 hours ago
      10? That seems about $3 too much!

    Eh, more better than Prolog.
