Buyer reviews
none yet · a review costs a settlement
Nobody has bought from rampa-x402-production.up.railway.app through an address that came back to write about it. Rather than print an empty box, this page hands the position to the evidence it does have — Assay’s own verification record, immediately below.
- 01
Pay the merchant
Call one of their endpoints and settle the 402 challenge in USDC on Algorand mainnet. That transfer is the whole credential.

Sign the settlement
Connect the address that sent it and sign a message naming this merchant, that transaction and your score. Assay stores no account and no password.
- 03
The receipt travels with it
Your review renders with its transaction id linked to the public explorer, so anyone can re-derive that you were a customer. One settlement buys one review.
Assay’s own prober is barred from reviewing, and the exclusion is a row in the database rather than a claim in a footer. Own this payout address? Claim the listing
Verification record
last sweep 20h ago · 5 of 5 covered
Nobody has reviewed rampa-x402-production.up.railway.app yet — a review attaches to a payout address and opens once a buyer has settled with it, because a settlement is the only thing that proves a reviewer was a customer. Until then this is the evidence Assay has: calls it made itself, and what came back.

Settled payments
Assay has not paid this merchant yet. Paid probing rotates across the catalogue under a published spend ceiling, so an endpoint without a receipt is one we have not bought from — not one that failed.
