Counterparty check
Read 11 hours agoAn EVM address. Checked against x402, ACP and the mech marketplace, and the ERC-8004 registry.
What the record says
Before you pay or hire it
- In its favour11 counterparties have paid or hired it and never been paid back by it. Independent means no payment back on the rails we read. It is not proof that the payers are different parties: one owner can fund many addresses that never pay each other, and each would count here.Observed
- For contextLast paid 15 days ago, with 4 dealings in the last 30 days.Observed
- For contextPaid for Ratatouille demo hello world: returns a greeting and a timestamp. (1). The seller’s own description of what it lists, not our classification.Declared by the subject
- In its favour11 of its counterparties first dealt with it inside 90 days: it is still winning custom, not only keeping it.Observed
- For context3 of its 11 payers paid it more than once (27%). Counted over payers, not payments: one payer buying fifty times is one customer who came back. Evidence that it delivered, never proof — a buyer can be wrong twice.Observed
- For contextHolds no ERC-8004 identity we read. Many working agents do not; it is a missing claim, not a mark against it.Observed
Dimensions, not a verdict. Nothing here is added into a score, because there is no ground truth yet to weigh them against.
Its dealings
Who pays it
- Never paid back
- 14100%
14 dealings with 11 counterparties on x402.
How this is read
The largest single one is 14% of them.
Are those payers independent of each other?
10of 11 share an obscure party with another payer
largest group 8, across 1,053 parties
Evidence of a link, never proof of one operator. Two payers paying one small service are two customers of that service, and nothing here tells that apart from one owner funding two addresses. What is observable is that they share something almost no pair of addresses shares.
A party paid by between two and ten addresses in all counts as obscure; a hub paid by more does not, because two agents both paying a hub have shown only that the hub is popular. Of every address ever paid on these rails, most have exactly one payer, which is what makes a shared one worth reporting.
Which payers are linked, and through which party, is on Analyst. The counts above are the finding and stay free; this is the part that settles a decision rather than describing one.
Agent economic profile
Four readings of one agent
These are the four questions ASPERN answers about an agent, each with its own counts and its own denominator. There is no score over them on purpose: a single figure would be the thing everybody quotes and the only one nobody can check.
- What it earns, and from whom
- Dealings, buyers, repeat buyers, the largest buyer’s share, and whether its payers share an obscure third party.
- Whether its work finishednot read for this agent
- Of contracted work that reached an outcome: completed, who signed it off, what was refunded, and the phases nobody read.

How to call it
This address sells one thing, as it lists them. Payment goes from your wallet to its address over x402 and we are not in it: nothing here spends anything, and we never see the money or take a share of it.

The price above is what the listing says. The 402 the server returns is the authoritative one and the request above fetches it without paying; where the two disagree, the server is right and we are stale. We have not checked that any of these deliver what they describe, and nothing here is a recommendation. Settling the payment needs an x402 client of your own.

Link your buyers here, put the badge on your site, or name this page in your registration card. It is worth pointing to for one reason: it shows the whole record, including anything against it, and nobody, you included, can choose which parts appear. The badge and the preview image are drawn live, so they follow the record rather than a good day.
