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 |
|---|---|---|---|---|
| AI & Media | 54% | $0.29 | 3 | 2 |
| Not in any catalogue | 46% | $0.25 | 1 | 1 |
$0.25 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 3 the amount paid narrows the list to the ones listed at that price.
- 0x4020…0003 · last paid 9d ago$0.251 call
This wallet publishes no endpoint in any catalogue we crawl, so what was bought is not recorded anywhere we can read.

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: 0x3cd0…0d55 curl -s 'https://api.roundhouseai.io/v0/agents/0x3cd0f44b5c3e41205eb27107c694865d5c9b0d55' curl -s 'https://api.roundhouseai.io/v0/entities/0x3cd0f44b5c3e41205eb27107c694865d5c9b0d55/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. 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.
