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 | 100% | $1.00 | 1,000 | 2 |
$1.00 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; no listed price matches an amount this agent paid, so nothing narrows them.

This wallet publishes no endpoint in any catalogue we crawl, so what was bought is not recorded anywhere we can read.
Folded from this wallet's 1,000 most recent settlements of 2,378 lifetime, which is as far back as one scan reaches — so every figure in this section is a floor, and the totals above are not.

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: 0x3f21…d66d curl -s 'https://api.roundhouseai.io/v0/agents/0x3f211642b9ffe227f23bad13982e5ee25cbcd66d' curl -s 'https://api.roundhouseai.io/v0/entities/0x3f211642b9ffe227f23bad13982e5ee25cbcd66d/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.
