What we saw: vet402 signed the payment and the paid request got a 4xx other than 402, with no settlement receipt and no transaction on the row. No money moved, and vet402 cannot rule out that its own request was the problem (held_reason unsettled_4xx), so the row is not counted against the seller. Since 2026-09-16 23:25 UTC vet402 sends the request body the seller's 402 declares (an empty JSON body when it declares none), and since 2026-09-27 23:27 UTC it adds the query parameters the seller's 402 declares on Base.Last result about the seller: none among the attempts shown.

2.How to read this

Each listing shows its latest attempt on Base and up to four earlier ones. A row where vet402 signed a payment and sent the paid request is an L1 result (“Recorded (L1 paid purchase)”); a row where vet402 did not sign is marked “not bought” and is not an L1 result. The listing's record page also shows the L0 state (“Published state”), which checks that an unpaid request gets a valid 402, so a listing can pass L0 and still fail here. Whose side puts a failure on the seller's side when the row shows vet402 was not at fault: it signed on the listing's terms, its wallet held the price, it sent the declared input, and the seller answered explicitly or had its declared time. Even then, one such failure is “not sorted: one failure so far”: a failure goes on the seller's side only when the same listing has one on two different days (UTC), and those rows are marked “under re-check” while we re-check them. A row that cannot show all of that is “not sorted”, and so is a held row (held_reason in the export), a failure where no payment was taken (“no charge”), and a payment that settled before the seller refused an input vet402 had not sent. “Signed payment” and “Answer to the paid request” show what the row recorded, and nothing else: the answer's body and header values are not published. The maxTimeoutSeconds on a row is the listing's value today; a declared price or address on a not-bought row is the value recorded at the time of the attempt. The transaction link opens the settlement on Basescan. Listings removed from the Bazaar, and listings whose catalog network is not Base, are not on this page. The fix-first page groups the same results across sellers (methodology).

3.Think a row is wrong?

Use “Dispute this purchase” on the row: it opens Dispute this record on the listing's record page with the purchase time filled in. Say what you saw instead. The row is not deleted on dispute; a correction is published with the same weight.
