Data quality

Not enough of this address's history was examined to assess it: self_dealing and counterparty_concentration and single_counterparty were computed over the 1000 most recent settlements scanned (its history is longer than the 2000-row scan cap), so nothing found there rules anything out. This is an incomplete check, not a clean record.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
