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 | 46% | $0.07 | 5 | 5 |
| Company & People | 31% | $0.05 | 4 | 1 |
| Web & Content | 14% | $0.02 | 2 | 1 |
| AI & Media | 7% | $0.01 | 1 | 1 |
| Onchain Data | 3% | $0.005 | 2 | 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 8 of 9 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: Lumen Investment Research curl -s 'https://api.roundhouseai.io/v0/agents/0xfdfadd01edcbabe025931e45cdc8532b00218500' curl -s 'https://api.roundhouseai.io/v0/entities/0xfdfadd01edcbabe025931e45cdc8532b00218500/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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
