Verified Accuracy certificates

Your customers have seen every accuracy claim. A certificate shows them a number they can check: your product's measured accuracy on real classification decisions, graded exactly by an independent lab, with a public page anyone can open.

How it works

You run the test. Your product classifies 200 real decisions issued in 2026, through our API, exactly as it does for customers (about 10 lines of code). The answer keys stay on our servers, so the test can't be tuned to.
We grade every answer exactly against the code actually issued, at 2, 4, 6, 8 and 10 digits. No AI judge.
You see your results first, privately. Nothing is published unless you agree in writing.
We issue the certificate. It's a dated record with your product name, your scores and their 95% ranges, plus a page at xzar.si/certificate/<id> and a badge for your website.

What the badge shows

The badge always shows the live status. If the certificate expires or is withdrawn, the badge says so, so a customer who clicks it always sees the truth.

Sample only. The numbers are illustrative.

The rules

Fresh cases only: decided in 2026. The answer keys have never left our servers.
Enough cases to mean something: at least 200, all run within 30 days, with a 95% range printed next to every number.
Valid for 90 days: products change, and a certificate is a dated snapshot. Renew with a fresh run.
Your numbers only. No rankings and no comparisons with anyone else.
We can withdraw a certificate if it's misrepresented, for example used for a different product or version.

Launch price: $1,500 per certificate through December 31, 2026. From January 1, 2027 the price is $2,500. It covers the 200-case run, the certificate and the badge, valid for 90 days. Renewal: $1,000. A certificate is included with the full scorecard report. Email hello@xzar.si to start.

What a certificate is not

It reports measured accuracy of the named product on the dated case set shown, graded exactly against the decisions actually issued. It is not a legal guarantee, a compliance or safety certification, or a comparison with any other product. Results on other cases may differ. Terms · Privacy
