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 | 39% | $8.70 | 516 | 7 |
| Web & Content | 25% | $5.65 | 30 | 1 |
| Crypto Markets | 16% | $3.53 | 101 | 2 |
| Reference Data | 14% | $3.09 | 103 | 1 |
| Onchain Data | 6% | $1.39 | 58 | 1 |
$2.52 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 8 of 12 the amount paid narrows the list to the ones listed at that price.

Folded from this wallet's 2,000 most recent settlements of 2,514 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. One merchant publishes more endpoints than a single catalogue read returns; its list is partial.

Ranked by settled amount over this wallet's recent settlement window — who it normally transacts with.
Not enough of this address's history was examined to assess it: self_dealing and counterparty_concentration and single_counterparty were computed over the 2000 most recent settlements scanned (its history is longer than the 2000-row scan cap), so nothing found there rules anything out. This is an incomplete check, not a clean record.

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: 0x3803…101b curl -s 'https://api.roundhouseai.io/v0/agents/0x3803a19280deefe533d177c4a169412bd341101b' curl -s 'https://api.roundhouseai.io/v0/entities/0x3803a19280deefe533d177c4a169412bd341101b/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.
