Human judgment for AI agents

Give your AI agent access to real human judgment.

Send a question, claim, or draft to a human responder. Get back a clear verdict or a stronger answer your agent can use. A review costs 0.10 EUR to ask, then 2.90 EUR if a human answers within 60 minutes or 1.45 EUR within 24 hours. Reading the price and testing the connection cost nothing.

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.

01Send the requestThe 0.10 EUR admission confirms the request and places it in the human queue. Every later price is known before you pay it.

Test before you pay

Read the price without paying.

The documentation, MCP discovery, and the 402 Payment Required response are free. Your agent can send an unpaid request, receive a 402 with every price and the x402 requirements, and test the connection before it ever signs a payment.

01 Discovery and the price check cost nothing.
02 Every review is paid: 0.10 EUR to enter the queue, then 2.90 EUR or 1.45 EUR to unlock the answer, depending on when the human answered.
03 If no human answers within 24 hours, the request fails and the wallet's next admission is free, in the same asset.

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 EURC or 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.

# Send a request. An unpaid request returns a 402 with every price and the payment to sign.

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

A fast answer costs more. A slow one unlocks for half.

Every review has three gates, priced in euros: a 0.10 EUR admission, then one unlock. The unlock price is fixed by when the human answered, never by when your agent collects the answer.

Free to try

0 EUR to read every price

Discovery and the price check

The docs, MCP discovery, the status endpoint, and the 402 response are free.
An unpaid request returns a 402 with every price of the review and the x402 requirements.
Test the connection and read the price before you sign a payment.

Pay as you go

0.10 EUR admission, gate 1

Gate 2, answered within 60 minutes2.90 EUR

Gate 3, answered within 24 hours1.45 EUR

Pay in EURC or USDC on Base. EURC pays the euro prices. USDC pays them converted at the ECB euro reference rate, rounded up to the next cent: at 1 EUR = 1.17 USD, 0.12, then 3.40 or 1.70 USDC.
The asset of the admission binds the review. The unlock is paid in the same asset.
There is no cancellation. Paying the admission commits to unlocking at one of the two prices.

If no human answers within 24 hours, the request fails and nothing more is charged. The same wallet's next admission is free, in the same asset. The unlock of that next review is paid as usual.
