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.
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 the exact price and 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 USDC to enter the queue, 2.90 USDC to unlock the answer.
- 03 If a request whose entry you actually paid fails without an answer, the wallet receives a 0.10 USDC entry credit toward gate 1 of its next request.
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.
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.

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.
A decision you can trace
The request, human outcome, timing, and payments remain connected, so the result never loses its context.
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.
Discovery and the price check
