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 |
|---|---|---|---|---|
| Web & Content | 69% | $0.29 | 41 | 1 |
| Not in any catalogue | 18% | $0.08 | 14 | 2 |
| Crypto Markets | 12% | $0.05 | 10 | 1 |
$0.08 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 2 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: 0xb9f5…45a5 curl -s 'https://api.roundhouseai.io/v0/agents/0xb9f5990da28c7d4f5393008d8a8cf52dc0f045a5' curl -s 'https://api.roundhouseai.io/v0/entities/0xb9f5990da28c7d4f5393008d8a8cf52dc0f045a5/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.
