Your AI can hire real humans.
When your agent hits a judgment call a model shouldn't make alone, it calls one API. 5arz routes the task to a verified, identity-checked person, returns a signed answer your agent can trust, and settles payment automatically. A human in the loop — on demand, at API speed.
One call out. A verified human answer back.
Your agent posts a task
Send the task and acceptance criteria to the 5arz API — a label, a judgment, a real-world check, anything a model shouldn't decide alone.
We dispatch to verified humans
The task routes to people whose government identity was checked via Stripe Identity and who passed Proof-of-Human. No bots, no duplicates.
A real person completes it
An accountable human does the work to your criteria. Quality controls and consensus run automatically where you need them.
Signed result + auto-settlement
Your agent gets the answer plus a signed verified-human attestation — and payment settles programmatically (agent-pay / x402).
Human judgment your agent can prove.
Every answer comes back with a cryptographic receipt that a real, accountable person produced it.
Verified, accountable human
Each task is done by an identity-verified, unique person — not a model, a bot farm, or a duplicate account.
Signed attestation
Results carry a signature you verify server-side, plus a stable anonymized worker reference and an audit trail.
Agent-native
Built for autonomous workflows: programmatic dispatch, webhooks, and automatic payment settlement — no human in your billing loop.

Questions builders ask.
What does "verified human" mean here? +
Every task is completed by a person whose government identity was checked via Stripe Identity and who passed Proof-of-Human. Each maps to one stable, anonymized reference — a real, unique, accountable human, not a bot or a duplicate.
How does my agent authenticate and call it? +
You create a business account, get API credentials, and POST tasks to the 5arz API. Results return via webhook or polling — designed to be called by autonomous agents, not just dashboards.
How is payment handled? +
Settlement is programmatic, built for the agent-pay era (x402-style). Your agent funds tasks and payment settles automatically when verified work is accepted — no human in your billing loop.
Can I trust the attestation? +
Yes — it's signed. You verify the signature server-side and get a stable worker reference, method, and timestamp. The verified-human + proof-of-work approach is covered by USPTO Provisional Patent 63/979,474.
What kinds of tasks work best? +
Anything a model shouldn't decide alone: preference/eval ratings, content-moderation edge cases, data verification, transcription, and real-world checks.
How fast are results? +
It depends on task type and pool — many tasks return in minutes. Scale plans get priority routing and higher throughput.
