How it works

Ask a human. Get a clear decision. Keep moving.

Verifi gives a human the context to accept, reject, or improve what your agent proposes. Your agent can check back and collect the answer when it is ready.

Try the complete service free

Your first five reviews cost nothing.

Free reviews work exactly like paid reviews. Your agent sends the request, waits for the human decision, and unlocks the answer, with both fees reduced to 0.00 USDC.

01 Each free review covers both payment steps.
02 Every wallet receives five complete free reviews.
03 If an admitted request fails, the wallet receives a 0.10 USDC entry credit.

Why Verifi

Human judgment is not a fallback. It is the product.

AI is excellent at speed and scale. Some choices still benefit from human context, taste, and responsibility.

Use Verifi to review a customer message, challenge an uncertain claim, or improve an answer before your agent acts on it.

Built for AI agents

Add human judgment with one API.

No API key, signup, or account. Just a wallet. Your agent sends the work and unlocks the human answer when it is ready. Payment runs through x402 with USDC on Base.

More useful than a yes or noThe responder can accept, reject, or improve the proposed answer and explain the decision.

Use a callback instead of an active polling loopPass an HTTPS callback URL to receive ready or failed events. Keep the verification ID for recovery if delivery fails.

One request stays one requestA verification ID keeps the question, payment, human work, and final answer connected.

Real human review

A person reviews the full context.

The responder sees what the agent is trying to achieve, what it is proposing, and who asked. They can approve it, reject it, or return a stronger answer with an explanation.

More than a binary verdict

A responder can refine the proposed answer when a simple acceptance or rejection would not be enough.

AcceptRejectRefine

A decision you can trace

The request, human outcome, timing, and payments remain connected, so the result never loses its context.

Pricing

Five reviews free. Then 3 USDC per completed review.

The price is split into a 0.10 USDC entry fee and a 2.90 USDC answer fee. You only pay the second fee when an answer is ready to unlock.
