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
14 dealings with 1 counterparties on x402. The largest single one is 100% of them.
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 /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.
Declared. ERC-8004 registrations held by this address.
Observed. Our probe asks each declared MCP or A2A endpoint.
Observed on the rails.
This address sells 4 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/0xcde02cb53da623d929fef26d56c1cd9ddc9ca880"}The same record, machine-readable, free and without a key.
https://aspern.org/api/v1/agents/0xcde02cb53da623d929fef26d56c1cd9ddc9ca880/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.
Value is the priced part only, and a dash where nothing was priced. It is never shown as zero.
Steady: one party accounts for about as much as it always has.
curl -i https://signalsfeed.com/api/v1/macrocurl -i https://signalsfeed.com/api/v1/semiconductorThe 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.
