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 |
|---|---|---|---|---|
| Crypto Markets | 59% | $5.11 | 157 | 5 |
| Web & Content | 40% | $3.43 | 556 | 3 |
| Reference Data | <1% | $0.04 | 2 | 1 |
| AI & Media | <1% | $0.02 | 3 | 1 |
| Not in any catalogue | <1% | $0.02 | 2 | 2 |
$0.02 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 10 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: 0x57b2…577d curl -s 'https://api.roundhouseai.io/v0/agents/0x57b2529984df3c6f66cb7e72e3bcd73bf7ae577d' curl -s 'https://api.roundhouseai.io/v0/entities/0x57b2529984df3c6f66cb7e72e3bcd73bf7ae577d/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.
