3.L1 — real purchases

3 of 5 paid attempts settled on-chain, and 3 of those also returned a 2xx response (delivered). 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 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.

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 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).
delivered_no_receipt
the paid request answered 2xx without a settlement receipt.
L2 no_declaration
the listing declares no output schema to check the response against.
L2 mismatch
the response lacked fields the listing's output schema declares.
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).
3/5
Figure 2. Settle-through: one cell per paid attempt. Filled = settled on-chain, crossed = signed, and not settled on-chain.

Embed this record

Run this endpoint? Show the settle-through record vet402 measured — the badge reads 3/5 settled · 3 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: 3 of 5 paid attempts settled with an on-chain receipt, and 3 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. (pro-api.coinmarketcap.com · measured 2026-09-25)

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

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.
