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 |
|---|---|---|---|---|
| Risk & Compliance | 41% | $0.15 | 28 | 1 |
| Not in any catalogue | 34% | $0.12 | 32 | 7 |
| Web & Content | 14% | $0.05 | 4 | 1 |
| Crypto Markets | 7% | $0.02 | 17 | 2 |
| Onchain Data | 4% | $0.02 | 15 | 1 |
$0.02 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 10 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: 0xa831…09fa curl -s 'https://api.roundhouseai.io/v0/agents/0xa831042b5b4448e7da41ac4c14d4282b606a09fa' curl -s 'https://api.roundhouseai.io/v0/entities/0xa831042b5b4448e7da41ac4c14d4282b606a09fa/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.
