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 | 47% | $0.19 | 40 | 1 |
| Not in any catalogue | 24% | $0.10 | 50 | 7 |
| Crypto Markets | 21% | $0.08 | 39 | 3 |
| Web & Content | 8% | $0.03 | 1 | 1 |
Every merchant paid publishes at least one catalogued endpoint.
Services it paid
A settlement carries the payee and the amount, never the URL. These are the endpoints each payee publishes; for 12 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: 0x9a8e…cc8e curl -s 'https://api.roundhouseai.io/v0/agents/0x9a8e1d05c1dfe7810f68b5b0206e5868bec8cc8e' curl -s 'https://api.roundhouseai.io/v0/entities/0x9a8e1d05c1dfe7810f68b5b0206e5868bec8cc8e/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.
