3.L1 — real purchases

1 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).

1 of those paid attempts are held as inconclusive rather than counted against this seller (1 settled and answered 4xx, 0 answered 4xx with no settlement receipt, 0 answered 402 or 5xx while our own payer wallet was out of USDC, 2026-09-13 00:00 to 2026-09-15 23:49 UTC). A 4xx says the request was not one the server would accept, and we cannot rule out that the request was ours to get wrong: vet402 buys with no API key of the seller's, and sends a POST body only when the seller declares one. This is the same principle the methodology already applied to path_template URLs, applied to the body and the authentication header as well. The rows are not deleted and not hidden — they are below, with their status and HTTP code, and they are out of the denominator for delivered (corrections).

Terms in this table

settle_failed
vet402 signed a payment and got no settlement receipt back.
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.
settled_4xx
held_reason in the export: the payment settled, then the paid request got a 4xx.
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 signed
vet402 signed a paid request. vet402 has not settled it on chain yet, or settlement failed, or the seller returned goods without a receipt.
Stage inconclusive
vet402 holds the row because the paid HTTP response was 4xx, or vet402's payer wallet was unfunded in a recorded window. vet402 keeps the row public in its own stage, apart from delivered and not_delivered.
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).

Run this endpoint? Show the settle-through record vet402 measured — the badge reads 1/2 settled · 0 delivered · 1 inconclusive 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: 1 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. 1 paid attempt is held as inconclusive rather than counted against the seller: a paid request that answered 4xx, settled or not, can be our own request being malformed, because vet402 buys with no API key and sends a request body only when the seller declares one; and a 402 or 5xx from 2026-09-13 to 2026-09-15 came while vet402's own payer wallet was out of USDC. A measurement of what happened when vet402 paid this endpoint, not a recommendation. (api.loyalspark.online · measured 2026-10-27)

4.Catalog listing events

No listing changes observed.

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. A dispute filed on the record form puts an active listing on a priority list. L0 runs probe that list before their ordinary queue, one run at a time. A listing whose URL has an unfilled path parameter is not put on that list. One run measures up to 50 priority listings, at most 5 from one site. Published fails whose catalog declaration changed, or that rest on probes recorded under earlier rules, take places first, and disputes fill the places left. A listing probed in the past 60 minutes waits for a later run. A dispute that no run reaches within 7 days leaves the list. The scheduled L0 run is at 10:30 UTC, and an L0 run at another time can measure the listing first. The record stays on this page. When a run measures the listing, the new probe is added to its history. 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.
