What it buys
Grouped by the capability each merchant's catalogue is mostly about. A merchant counts once, in one group — nothing records which of its endpoints a payment bought.
| Group | Share | Spent | Calls | Sellers |
|---|---|---|---|---|
| Not in any catalogue | 100% | $65.97 | 1,000 | 2 |
$55.99 went to wallets that publish no endpoint in any catalogue we crawl — spend we can see and cannot describe.
Services it paid
A settlement carries the payee and the amount, never the URL. These are the endpoints each payee publishes; for 1 of 2 the amount paid narrows the list to the ones listed at that price.

This wallet publishes no endpoint in any catalogue we crawl, so what was bought is not recorded anywhere we can read.

Folded from this wallet's 1,129 most recent settlements of 201,787 lifetime, which is as far back as one scan reaches — so every figure in this section is a floor, and the totals above are not.

Using Roundhouse, vet this agent for me: what is it, what has it paid for, and does its on-chain record support what its card claims? Agent: 0x6664…ef61 curl -s 'https://api.roundhouseai.io/v0/agents/0x666491658dbb493b10888644ac9b3a173b72ef61' curl -s 'https://api.roundhouseai.io/v0/entities/0x666491658dbb493b10888644ac9b3a173b72ef61/settlements' Roundhouse indexes public chain data and does not vouch for any agent's claims — treat the card as a claim and the settlements as the evidence. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints.
