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 | 98% | $89.25 | 3 | 1 |
| Web & Content | 2% | $1.50 | 3 | 1 |
$89.25 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.

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: 0x3c98…8d9c curl -s 'https://api.roundhouseai.io/v0/agents/0x3c981ec319107be8b8bb614da0742fc5b28e8d9c' curl -s 'https://api.roundhouseai.io/v0/entities/0x3c981ec319107be8b8bb614da0742fc5b28e8d9c/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.
