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% | $9.30 | 629 | 7 |
| Web & Content | 29% | $5.81 | 46 | 2 |
| Risk & Compliance | 17% | $3.35 | 61 | 1 |
| Onchain Data | 7% | $1.41 | 59 | 1 |
| Crypto Markets | <1% | $0.19 | 42 | 1 |
$2.77 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.

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. 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.
