Know who did it.
Verifying that a real human did something is free, forever — unlimited, self-serve, no card. You pay for the dashboard, the history, and the alerts. Start with an API key in one call, or let your AI agent sign itself up through MCP.

Most of what reaches you isn’t a person.
In 2025 automated traffic passed human traffic for the first time in a decade. Every system you run that assumes a person is on the other end is running on an assumption that stopped being true.
Detection is losing. Any filter that guesses whether something is human is grading a target that improves faster than the filter does. The only thing that holds is the opposite move — have a real person sign for it at the moment it happens, and let anyone check that signature afterwards.
Real people, verified on the phones they already own.
About thirty seconds to verify. No orb, no appointment, no hardware — and nothing about their face ever leaves the device.
Illustrative photography.
Three things ship on day one.
No pilot, no integration project, no sales call. An API key, a credential format, and a page anyone can check.
Drop it on a dataset, a profile, an article, or an ad slot. It links to a public page where anyone can verify the signature without an account.
History, monitoring and alerts on your own fingerprints. The free tier returns the same data as raw JSON — you only pay when you want to look at it here.
What do you need to verify?
Every answer below is free to start — unlimited verification, no card, no sales call.
An ID card can’t tell an AI lab whether the label in row 3,417 came from a person. A seal can.
“Are my users real people?”
Confirm a live human is behind a signup, a login, a review, or a payment approval — without collecting their identity.
Verify humans →“Was this training data made by humans?”
Labels, images and text with a signed mark on every row. Provenance you can hand an auditor.
Ground-truth data →“Did a person actually make this content?”
Seal photos, video, audio and text at the moment of creation. Anyone can check it later, offline.
Content authenticity →“Is my ad traffic human?”
Roughly one in five impressions carries invalid-traffic signals. Buy verified human attention instead.
Human traffic →“Is a real person behind this agent?”
Payment rails prove the agent paid. We prove a human authorised it — the missing half of agentic commerce.
Agent transactions →“I need real people to do work.”
Hand off a task, get clean results back, with proof a verified human did each one.
Get tasks done →Not sure which? Start free — one key covers all of it.

Proving a real human did something costs you nothing, at any volume, forever. Subscriptions buy the dashboard, the history, the monitoring, and the scale.

Questions buyers ask first.
What exactly is 5arz for Business? +
A marketplace for verified human work. Companies and AI agents buy ground-truth data, completed tasks, identity verification, human traffic, and brand research from an identity-verified workforce — with proof on every output. Pick the service you need above for the full breakdown.
How do I know a real human did the work? +
Every contributor is verified through Stripe Identity, and each output carries a proof-of-work record — contributor reference, timestamp, dwell time, anti-fraud signals — plus a signed attestation you can export and audit. The verification approach is covered by USPTO Provisional Patent 63/979,474.
How does billing work? +
Verifying humans is free at any volume, forever. Subscriptions ($0 / $99 / $499 / $2,499 per month) buy the hosted dashboard, retention, monitoring, and scale. Marketplace work is still funded with Stripe and billed on accepted output. Document-grade identity checks are metered at close to our vendor cost.
Can my AI agent hire humans directly? +
Yes. Your agent calls our API, 5arz dispatches the task to verified humans, and the result is returned with a signed verified-human attestation — payment settles automatically. See the AI hires humans page.
How fast can I start? +
Create a business account and post your first task in under five minutes. Self-serve flows need no sales call; API access and enterprise onboarding are available for higher volumes.
