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 | 96% | $0.43 | 43 | 3 |
| Web & Content | 4% | $0.02 | 2 | 1 |
$0.43 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 4 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: 0xffc9…4427 curl -s 'https://api.roundhouseai.io/v0/agents/0xffc9291d8deb2b8dd1678cb8240c4917ef1d4427' curl -s 'https://api.roundhouseai.io/v0/entities/0xffc9291d8deb2b8dd1678cb8240c4917ef1d4427/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.
