3.L1 — real purchases

2 of 2 paid attempts settled on-chain, and 0 of those also returned a deliverable 2xx response (delivered: other than 202 Accepted with a non-empty body). Each settled row carries its on-chain transaction hash, and that transaction is the evidence. On this page a receipt means the seller's own settlement receipt (PAYMENT-RESPONSE); a settled row can have none (see “tx from our index”). A settled row reads as nonce-bound when the on-chain re-read matched the one-time value stored for that purchase, so the transaction is the one for this purchase. Stellar is not in this count. The Stellar re-read checks payer, payee, amount and asset. A row reads as amount + payee when the re-read matched payer, payee, amount and asset and did not bind a one-time value. That tier holds rows from before 2026-09-04 and Stellar rows. They keep the settled label rather than being demoted (methodology). settled is the transfer vet402 confirmed on-chain. delivered is a 2xx other than 202 with a non-empty body. A settled row whose paid request answered 5xx counts as settled and not as delivered. definitions.

A row marked tx from our index came back with no settlement receipt from the seller. Our own index of on-chain settlements found the transfer afterwards — our payer, this endpoint's payee, the exact amount, inside the time window — and the row goes through the same on-chain re-read as any other before it reads settled. The seller did not name that transaction; we did (methodology).

Terms in this table

settled (nonce-bound)
vet402 re-read the transfer on-chain in that chain's pinned settlement asset, and the on-chain re-read matched the one-time value stored for that purchase, so the transaction is the one for this purchase. Stellar is not in this count.
L2 not_checked
not checked: the paid request did not answer 200, so there was no response to check against the listing's output schema.
Stage not_delivered
vet402 re-read the payment on the chain. The paid request returned 5xx, or another HTTP status outside 2xx that vet402 does not leave in settled. vet402 counts HTTP 4xx as inconclusive. vet402 leaves 202 Accepted, HTTP 2xx with a body vet402 recorded as empty, and no HTTP status on record in settled. This stage does not say whose side the failure is on. See Whose side.
Whose side
the same words as the seller page: seller's side only after failures on two different days (UTC), marked “attribution under review”; vet402's side; or not sorted (the rules).

Embed this record

Run this endpoint? Show the settle-through record vet402 measured — the badge reads 2/2 settled · 0 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 0 of those also returned a deliverable HTTP 2xx response. settled is the confirmed transfer; delivered is a 2xx other than 202 with a non-empty body. A measurement of what happened when vet402 paid this endpoint, not a recommendation. (modal.mpp.tempo.xyz · measured 2026-10-10)

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

5.Dispute this record

A dispute does not start a purchase. The signed dispute route runs one fresh L0 check, an unpaid request.

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. This listing is not active in the catalog, so a dispute filed on the record form does not put it on the re-probe list. The record stays on this page. The scheduled L0 run is at 10:30 UTC. This listing is not on that run. Send the dispute to support@vet402.com. Published corrections are listed at /corrections. Operators who control the receiving address can also sign a dispute via POST /api/v1/observatory/disputes (API reference). That route runs one fresh L0 check under the normal publication gate. A later purchase comes from the regular schedule.
