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
2,461 dealings with 350 counterparties on x402, Virtuals ACP.
The largest single one is 16% of them.
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, 96% 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.
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.
Declared. ERC-8004 registrations held by this address.
Observed. Our probe asks each declared MCP or A2A endpoint.

Otto AI - Trade Execution Agent sells 15 things, 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.

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/0x5bb4b0c766e0d5d791d9403fc275c22064709f68"}The same record, machine-readable, free and without a key.
https://aspern.org/api/v1/agents/0x5bb4b0c766e0d5d791d9403fc275c22064709f68/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.
The four together, as one answer an agent can read, are /v1/agents/{address}/profile and the agent_economic_profile 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.
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
1,668 jobs from 160 clients, 2026-03-20 to 2026-11-02.
A third party signed off 70 of the 515 completions, the buyer 444, and 1 carry no evaluator at all. 32 were refunded.
Steady: one party accounts for about as much as it always has.
| What they are | Parties | Paid | How we know |
|---|---|---|---|
| Named as a provider | 1 | $1.0k | 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 | 0 | — | 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.

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.
Otto AI - Trade Execution Agent 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; online now, last active today, 98.7% of its jobs successful by Virtuals' count.
