Proof a real human did it.
Verification is free.
5arz seals verified human work — a survey answer, a labeled row, a review, an approval — with a signed credential proving a real, ID-verified, live person did that exact thing. Anyone can check it in under a millisecond, offline, against our public keys.
These are the keys every seal is checked against.

Most tools prove a human exists.
We prove a human did it.
That’s the difference between an ID card and a receipt.
An ID card can’t tell an AI lab whether the label in row 3,417 came from a person. A seal can.
Proving a human exists is table stakes.
Proving a human did this is what buyers pay for.
An ID card can’t tell an AI lab whether the label in row 3,417 came from a person. A seal can.
Put proof on anything a person does.
Survey answers, labeled data, reviews, clicks, approvals — if a real person did it, 5arz can seal it, and your customers can check it without ever calling you.
Four steps. No trust required.
5arz is the proof-of-human-work layer. Our core product is the seal — a signed mark that proves a real, ID-verified, live human did a specific thing — a task, a view, an action, a payment approval — and anyone can verify it against our public keys, trusting no one. Think of it as an SSL certificate, but for a real human instead of a website. The app where people earn Stars for verified work is how we source those humans — the supply side, not the whole company.
Verify the human
A partner ID check (Stripe Identity or Didit) plus a liveness check confirm a real, present person on a normal phone. No orb, no hardware — 5arz never receives the selfie or ID image.
Issue a signed credential
5arz stamps that exact action with a signed Proof-of-Human credential — an ES256 token tied to one verified person, one action and one moment.
Anyone can verify it
The credential checks against 5arz's public keys in under a millisecond — offline, no re-scan, no trusting 5arz. Like an SSL padlock, but for a human.
Use it anywhere
Verified-human data for AI, verified human attention for ads, on-chain personhood checks, human-made content, and human proof for agent payments.
Verification is free. Pay only for the dashboard and scale.
Checking a seal is always free, unlimited and offline. Issuing seals uses your plan's monthly allowance — 1,000 a month on Free. And we never charge a person to prove they are a person.

Add it to your device once. From then on, any site, app, or AI agent can confirm a real person is here — without you handing over your name, your face, or your documents.
Add it to your device
About two minutes on the phone you already have. No orb, no appointment, no office to visit, no hardware to buy.
We verify it’s really you
A live check confirms a real person is present — not a bot and not a recording. Your credential is signed and it’s yours to carry.
Your face never reaches us
Your selfie and ID go only to our verification partner. 5arz never receives, stores or sells them — only a signed result travels.
Free at signup, free every time you use it, free forever. Businesses pay for dashboards and data — you never do.
Once you’re verified you can also earn on tasks, seal your own photos and video as human-made, and prove your work is yours. All optional. All free.

You proved the payment.
We prove the human.
Every company runs KYC to know their customer. The AI era needs one more layer: Know Your Human — a reusable credential that a real, ID-verified, live human is behind an action. Verify once, then prove it anywhere: to any site, any payment rail, or any AI agent.
Know Your Human
The reusable complement to KYC. Verify once, then prove you're a real, ID-verified, live human anywhere. Your ID and selfie are checked by our verification partner (Stripe Identity or Didit) — 5arz never receives them, and anyone can check the credential.
Explore Know Your Human →Agentic commerce
Payment networks let AI agents pay. 5arz binds the human, the agent, and the payment into one signed credential — and proves a real human did the work.
See agentic commerce →The moat: verify once
Speed — a sub-millisecond credential check, no re-scan. Privacy — no orb, and 5arz never receives your face. And the part most stop short of: proof the human actually did it.
Why 5arz is different →More than half of web traffic is now automated. Every system you own assumes a person unless something proves otherwise — an assumption that is now wrong more often than it is right. One signed credential fixes it, and anyone can verify it offline without trusting us.

The honest answers.
What does 5arz actually sell? +
A signed credential proving a real, ID-verified, live human performed a specific action — verifiable by anyone, offline, against public keys. Platforms, AI companies and AI agents use it to prove the work they deliver came from a real person.
Is verification really free? +
Yes. Checking a seal is always free, unlimited and offline, with no card. Issuing seals uses your plan's monthly allowance — 1,000 a month on Free, with API + MCP access. Paid plans at $99, $499 and $2,499 a month add the dashboard, history, alerts and scale.
How do I check a seal without trusting you? +
Every seal is an ES256-signed token. Fetch our public keys (JWKS) once and verify with any standard JWT library, offline. Change one character and it fails. You never have to call us.
Does a seal prove someone has only one account? +
No, and we say so plainly. A 5arz credential proves a specific ID-verified person did a specific thing. It does not establish that the person holds only one account. If you need one-person-one-entry, pair us with a uniqueness signal of your own.
I want to earn. How does that work? +
Verify once with Stripe Identity, then do short tasks like rating AI answers or labeling images. Each task earns Stars, logged to your balance with a receipt. Cash-out is paused right now; every Star you earn is recorded and stays yours. There is no income guarantee.
Is my information safe? +
ID and liveness checks run through our verification partners (Stripe Identity or Didit). 5arz never receives your selfie, your ID image or your face geometry — sites that check you get only a signed result. We never sell your personal data.
