Why it is new

What exists today, and what this does differently

Why own your own

Multi-model verification with signed receipts already exists; per-answer micropayments are the remaining twist.

Closest things out there

Synod (ETHGlobal) has multiple models vote and post a signed receipt onchain, MAMV produces vote receipts with onchain anchors, and Hive SiGR sells signed multi-model panel receipts.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The pitch, ready

Pay three independent AIs a few cents to check one answer, and get a signed receipt of agreement.

Problem: Professionals send AI written summaries to clients with their name on them, but one model can be confidently wrong and there is no record of how it was checked.

Solution: A panel of three verifiers from different labs is paid per check over x402, votes are aggregated by the user's rule, and an attestation records the document hash and votes.

Why now: x402 makes paying several models per request trivial, and cheap attestations make a verifiable receipt practical for every document.

Market: Freelance consultants, translators, paralegals and small firms that send AI assisted work to clients.

The ask: Pilot with 50 professionals and three model operators, plus ecosystem grant support.

For hackathons and demo days

Your 2 minute demo

Home: meet Priya, a contracts consultant in Lisbon with two summaries due.
Panel: pick three verifiers from different labs and set 3 of 3 with a cap.
Check: run the supply summary and watch two verifiers catch the renewal clause.
Check: unlock Professional through the USDC checkout and turn on claim mode; all three catch it.
Check: fix the line, recheck, and get the seal and share card.
Receipts: open the receipt with the document hash and the branded page.
Owner Revenue: change the margin and Professional price, and preview the Plans sheet.
Owner Growth and Roadmap: run an operator listing day, then request the verifier marketplace.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

More and more work that goes out under a person's name is drafted by one AI model. One model can be confidently wrong, and the person sending it has no cheap, quick way to get a second look or to show a client it was checked.

What exists and what is new

Multi-model verification with signed receipts already exists: Synod (an ETHGlobal project) has several models vote and posts a signed receipt onchain, MAMV produces vote receipts with onchain anchors, and Hive SiGR sells signed multi-model panel receipts. Research verdict: exists, low novelty. The remaining twist here is per-answer micropayments to independent verifiers over x402, a budget and panel picker for non-technical professionals, and claim by claim checks that must cite the source.

The data it runs on

The hash of the document being checked, the answer or summary under review, each verifier's vote and clause citations, x402 payment receipts and the resulting EAS attestation. Document text is sent only to the chosen verifiers and is never written onchain.

1.The mission

Make it normal and cheap to have AI work checked by independent eyes before it goes out with your name on it.

2.Why people can't resist it

Less than a coffee A three model check costs a few cents, so people run it on everything, not just the scary documents.

A receipt you can show Clients get a link with the seal: this exact file, these verifiers, these votes.

The Friday send-out Nothing leaves the outbox unsealed. A streak of clean Fridays is a quiet point of pride.

3.How it works for real

Upload and split: The app splits the answer into claims and pairs each with the source passages it should match. Text is hashed locally (SHA-256) before anything is sent.

Verifier panel: Three models from different providers via OpenRouter or direct APIs, for example a frontier reasoning model, a mid tier model and a small fast model. Each must cite a clause for every claim it accepts or rejects.

x402 payments: Each verifier endpoint quotes a price with HTTP 402; the app pays in USDC on Base only if the quote is within the user's per check budget, and never retries at a higher price silently.

Aggregation: Votes are combined with the user's rule (2 of 3 or 3 of 3). Disagreements are shown claim by claim with the verifier's reason.

Attestation: An EAS attestation on Base records the document hash, verifier ids, votes, rule and payment references. The schema is public so anyone can check a receipt.

Share page: A receipt page shows the seal and votes. Verifier notes are visible only to people with the link; the document itself is never published.

4.Cost per use and pricing

Per check: model tokens for a 2 page summary against a 10 page contract are roughly 0.5 to 5 cents depending on the models chosen; an EAS attestation on Base is usually well under 1 cent of gas. A user running 100 checks a month spends about 3 to 8 USD on verifiers and gas.

Pay as you go Cost plus 2 cents per check

Pick any three verifiers, pay per check, receipts included.

Professional 12 USD a month

150 checks, claim by claim mode, branded receipt pages and the Friday outbox.

Firm 49 USD a month

Shared panels for a team, custom verifier lists, audit export of every attestation.

5.Growth loop

Every receipt link sent to a client shows how the check was done and invites them to check their own documents. Verifier operators can list their own models and earn per check, which brings new supply and their audiences.

6.Risks and guardrails

False comfort: Three models can share a blind spot. The receipt says what was checked, not that the document is correct, and the app says so on every seal.

Confidentiality: Contracts are sensitive. Send text only to providers with no-training terms, let users pick self hosted verifiers, and keep only hashes onchain.

Correlated verifiers: Models from the same lab or trained on similar data agree too easily. Warn when a panel is not diverse and track each verifier's catch rate.

Price games: A verifier could raise prices mid request. Pay only against the quote, cap per verifier price, and log changes.

Not legal advice: The app checks consistency between a summary and its source. Professionals remain responsible for their own advice.

Now
Freelancers check AI drafted summaries before sending them to clients, for a few cents each.
Next
An open market of verifiers, each with a public track record of what they caught and missed.
Later
Email and document tools show a seal badge next to AI assisted work, and clients ask for it.
The big picture
Checking AI work becomes as cheap and routine as spell check, and trust in what people send each other goes up, not down.

Why own Second Look

People are sending AI written contracts, reports and summaries to clients with their own name on them, and they have no way to show it was checked. Second Look pays three independent AI verifiers a few cents each through x402 and issues a signed attestation of how far they agreed. If you own it, the verifier panel, the pricing margin and every receipt carry your brand, and you earn on each check instead of paying someone else's.

What’s stopping you?

“I can't code. Can I run a multi model verifier?”

Yes. The panel of three models, x402 payments, EAS attestation and receipt page are built. You choose the chain, models and branding, add your API keys and deploy from your wallet with the guide.

“Does three AIs agreeing mean the answer is right?”

No, and say so clearly. Agreement lowers the chance of an obvious error but models can share the same blind spot. Position the receipt as evidence of checking, not a guarantee of truth.

“What does it cost me to run?”

Each check pays the verifier models. Set your price above your cost, for example charge 25 cents for a check that costs you 8. Watch costs weekly and cap daily spend.

“Who would actually pay?”

Freelancers, consultants and small agencies who send AI assisted work to clients. Start with one profession you know, like contract summaries for freelancers.

“What about client confidentiality?”

Documents go to the model providers you choose. Tell users which ones, let them pick providers with suitable data terms, and warn them not to submit anything they are not allowed to share.

The million-dollar ladder

You charge per check (or a monthly bundle) and keep the margin above model costs. Teams pay monthly for a volume of checks plus branded receipts their clients can open.
