An EVM address. Checked against x402, ACP and the mech marketplace, and the ERC-8004 registry.
Dimensions, not a verdict. Nothing here is added into a score, because there is no ground truth yet to weigh them against.
Its dealings
1,458 dealings with 3 counterparties on Virtuals ACP.
The largest single one is 100% of them.
No pair of its payers pays the same obscure party on the rails we read. That is not proof they are unrelated: one owner funding addresses that never touch each other again leaves nothing for this to find.
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, 96% have exactly one payer, which is what makes a shared one worth reporting.
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.
The four together, as one answer an agent can read, are and the tool in the plugin. What no reading here can reach: revenue that never touched a rail we read, dependencies that are not payments, and whether completed work was any good. We can say who signed it off, not what they received.
Declared. ERC-8004 registrations held by this address.
Observed. Our probe asks each declared MCP or A2A endpoint.
Observed on the rails.
Blockticity Verified Infrastructure sells through the Agent Commerce Protocol: a job is opened and paid through the protocol on Base, not by calling a web address, so there is no endpoint here to knock on, and the inspect, payment-check and rehearse steps of the finder apply to x402 sellers. What it offers, as Virtuals publishes it; offline now, last active 203 days ago, 97.9% of its jobs successful by Virtuals' count.

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.

{"name":"ASPERN record","endpoint":"https://aspern.org/counterparty/0x52239f7acddd345ecdd0ad83d9d2e4ca493e05f0"}The same record, machine-readable, free and without a key.
https://aspern.org/api/v1/agents/0x52239f7acddd345ecdd0ad83d9d2e4ca493e05f0/checkJoined on this address alone: an operator paid on another key is another address here, and loops longer than two parties are not read yet.
Three figures that nest: what settled on-chain to this address, what of that is tied to a named service or order, and what of that carries a recorded delivery. x402 records payments and never deliveries, so those are counted apart. On a plan; see what it includes.
ACP jobs it took
1,458 jobs from 3 clients, 2026-03-20 to 2026-04-23.
A third party signed off 1,424 of the 1,424 completions, the buyer 0, and 0 carry no evaluator at all. 1 were refunded.
Not measurable over both spans yet.
| What they are | Parties | Paid | How we know |
|---|---|---|---|
| Named as a provider | 0 | — | a protocol named them the provider of a job: an ACP job taken, or a Masumi escrow they were the seller of |
| Publishes something for sale | 0 | — | they publish a paid resource in the x402 catalogue and this address paid them; that the payment bought that resource is not proven |
| Paid, nothing more known | 1 | $0.01 | money reached them and nothing we read says they sell anything: a relayer, a bridge, a refund and a salary are indistinguishable here |
Below three suppliers a share could only be a half or a whole, so none is drawn. The count is the finding here. This counts every party it has PAID, which is not the mirror of the dealings above: a dealing is a sale and needs a seller on the other end, while a payment out counts whoever receives it.
