How the402 decides

What a verdict is

One of four words about an endpoint: verified, degraded, failed, unknown. It is a statement about evidence the402 holds, issued at a time and valid until a time. When the evidence changes, so does the verdict. When the evidence goes quiet, the verdict expires into unknown rather than lingering.

‖ Paused the402 is not publishing the words degraded and failed about a named endpoint yet. Where one applies, a dated factual sentence stands in its place.

What the evidence is

the402's own checks of the endpoint; the results of purchases completed through the402 checkout; tasks solved in the proving ground; attestations signed by buyers who paid the endpoint; and the endpoint's on-chain payment history. Each source is weighted by how much it saw and how independent it is, and no single source can produce verified on its own.

What it is not

Not a review. Not a ranking anyone can buy. the402's own services are labelled first party and never scored. An unknown is a silence, not a failing grade.

Who is speaking

Every verdict is signed by the402's attestor key. The statement, its signature and the evidence root travel together, so anyone can check that the402 said it and that it has not been altered. Anchoring on Base lets anyone check a verdict against a public record.

Check a verdict yourself

Fetch the verdict by id from the trust API. The answer carries the typed data and the signature. Recover the signer and compare it with the attestor address the trust API publishes.

‖ Paused Verdicts are signed today. Anchoring is not switched on yet, so no verdict has been written to a chain.

Corrections

A provider who has claimed an endpoint can contest a verdict or a piece of evidence. A buyer can complain. A person reviews before anything changes, and every dispute and its outcome is public in the dispute register on the explorer.

Members

Paid checks run only for endpoints whose operator has claimed them and opted in, funded by that member or by a buyer verifying a claimed endpoint. the402 pays for no probes.

‖ Paused Paid checks are not switched on yet, and none has been paid for.

The record

Every verdict the402 has issued is kept and can be compared against what happened later. The accuracy page publishes that record as it accrues.

What is deliberately not published

The weights, thresholds and schedules behind a verdict. They change as the402 learns, and publishing them would help gaming more than it would help trust. What is published is enough to verify a statement, to dispute one, and to see how often the402 was right.
