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 |
|---|---|---|---|---|
| Onchain Data | 98% | $4.92 | 985 | 1 |
| Web & Content | 2% | $0.08 | 15 | 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 2 of 2 the amount paid narrows the list to the ones listed at that price.

Folded from this wallet's 1,000 most recent settlements of 2,046 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.

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: 0xb9dd…c3f9 curl -s 'https://api.roundhouseai.io/v0/agents/0xb9dd952f14b61197701dd7353a7767d8d6e8c3f9' curl -s 'https://api.roundhouseai.io/v0/entities/0xb9dd952f14b61197701dd7353a7767d8d6e8c3f9/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.
