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.
