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 | 42% | $0.16 | 25 | 6 |
| Crypto Markets | 28% | $0.11 | 31 | 3 |
| Web & Content | 19% | $0.07 | 10 | 2 |
| Risk & Compliance | 11% | $0.04 | 7 | 1 |
$0.09 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 9 of 12 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: 0x8a0d…0019 curl -s 'https://api.roundhouseai.io/v0/agents/0x8a0de799c5f8938d134a96694bf12a22b54c0019' curl -s 'https://api.roundhouseai.io/v0/entities/0x8a0de799c5f8938d134a96694bf12a22b54c0019/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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team.
