3.L1 — real purchases

2 of 2 paid attempts settled with a receipt, and 2 of those also returned a 2xx response (delivered). Each settled row carries its on-chain transaction hash — the receipt is the evidence. A settled row reads as nonce-bound when the on-chain re-read also matched the one-time signature nonce we generated for that purchase, and amount + payee when it matched amount, payee, asset and chain with no nonce on record — the binding shipped on 2026-09-04, so earlier rows carry the weaker evidence and keep their label rather than being demoted (methodology). settled is the transfer we confirmed on-chain; delivered is the response arriving. A settled row whose paid request answered 5xx counts as settled and not as delivered — definitions.

Terms in this table

settled (nonce-bound)
vet402 confirmed the USDC transfer on-chain, and the on-chain re-read also matched the one-time nonce vet402 signed for that purchase.
settled (amount + payee)
vet402 confirmed the USDC transfer on-chain; the on-chain re-read matched amount, payee, asset and chain; no nonce was on record (rows before 2026-09-04).
L2 no_declaration
the listing declares no output schema to check the response against.
Whose side
the same words as the seller page: seller's side only after failures on two different days (UTC), marked “under re-check”; vet402's side; or not sorted (the rules).
2/2
Figure 2. Settle-through: one cell per paid attempt. Filled = settled with an on-chain receipt, crossed = paid but no receipt.

Embed this record

Run this endpoint? Show the settle-through record vet402 measured — the badge reads 2/2 settled · 2 delivered and updates as the record grows. It carries the host it is about and the date it was last measured, so a saved copy cannot pass itself off as current. It states a measurement, not a rating.

vet402: 2 of 2 paid attempts settled with an on-chain receipt, and 2 of those also returned a 2xx response. settled is the confirmed transfer; delivered is the response arriving. A measurement of what happened when vet402 paid this endpoint, not a recommendation. (402.com.tr · measured 2026-09-10)

unverified is not a failure; a fail is published only after two consecutive failing probes. Definitions: methodology.

5.Dispute this record

Think a measurement above is wrong? Say which probe or purchase and what you observed instead. One person reads it and replies. The record is never deleted on dispute: if it was wrong, the correction is published with the same weight; if it was right, it stands. Operators who control the receiving address can also sign a dispute via POST /api/v1/observatory/disputes (API reference), which re-measures through the normal publication gate.
