Pricing
Five cents a check. That’s the whole price list.
No subscription, no seats, no tiers. Ounie credits are one cent each and are shared across every Ounie app, so the credits you bought for something else work here.

x402 on Base · no account, no key
- POST a domain, get a 402 quoting the terms, sign and retry.
- A malformed domain or a non-public address is refused with a 400 before any price is quoted.
- Payment is verified before the work and settled only after — nothing settles for an empty result.
- There is no refund on chain, which is exactly why the order is that way round.

A non-answer is free.
If not one of the six signals could be observed, the check has told you nothing — and Ounie does not charge for nothing. The reserve returns to the exact credit pools it came from.
5 credits reserved while the check runs.
Note the case that is not free: a check that resolved two or three signals bills normally. It did real work and gave you a real, if partial, answer — the band comes back insufficient so you know exactly how partial.
Questions
The awkward ones first.
Does a low score mean a business is a scam?
No, and the product will never say that. A low score means the public footprint is thin — which is what a business looks like in its first month, and also what a perfectly good local trader who has never bothered with a website looks like. It is equally what a throwaway storefront looks like. Trust Check hands you the six signals and their evidence so you can tell which, on the facts, for the transaction you are about to make.
Is this KYB?
No. Real Know Your Business checks a company against registries, beneficial-ownership records and sanctions lists, under a regulatory obligation, usually with documents. This is KYB-lite: it reads what is publicly observable about a domain in a few seconds, for five cents. Use it as a first-pass filter before a small transaction, not as compliance evidence.
Can a business game the score?
Partly, and the weights say which parts. Adding a privacy page and a footer address is cheap, so those weigh less. An organization-validated certificate means a CA checked a legal entity against a registry, and a five-year-old registration means five years — those cannot be bought this afternoon, so they weigh most. The review signal counts a link, is described that way everywhere, and carries the smallest weight in the model precisely because it is the easiest to fake.
What happens when a signal can't be read?
Its weight leaves the divisor. It is never scored as zero — that would punish a business for our blind spot, and would quietly change what the number means whenever an upstream went down. The response always tells you how many of the six resolved. Below three, no number is published at all: the band is
insufficient and score is null.Does a language model decide the score?
No. There is no model anywhere in the scoring path. Observations go into a pure function with fixed weights, which is unit-tested and published in full at
GET /api/pricing and through the MCP get_scoring_model tool. The same observations always produce the same number, and you can recompute any score we hand you.What does a check cost, and when am I not charged?
5 Ounie credits — five cents — drawn from the same wallet as every other Ounie app. If not one of the six signals could be observed, the check has told you nothing and the full amount is refunded. On the keyless x402 rail the equivalent is stricter: an on-chain settlement cannot be reversed, so nothing is ever settled for an empty result in the first place.
Can I check any URL?
Any public one. Addresses that cannot name a public site — loopback, private ranges, link-local, single-label LAN names — are refused with a 400 before anything is fetched or, on x402, before any price is quoted. A hostname that resolves into private space is refused at the same gate.
Do you store what I check?
Your own checks are kept on your account so you can re-read them for free. Keyless x402 checks are recorded without an owner, because there is no account to attach them to. We do not sell a directory of scored companies, and no business is listed or ranked anywhere on this site.
