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 | 30% | $1.75 | 14 | 5 |
| AI & Media | 29% | $1.64 | 19 | 2 |
| Crypto Markets | 23% | $1.31 | 20 | 2 |
| Web & Content | 8% | $0.45 | 19 | 1 |
| Reference Data | 6% | $0.32 | 9 | 1 |
| Onchain Data | 5% | $0.27 | 5 | 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 12 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: 0x3f52…3a8f curl -s 'https://api.roundhouseai.io/v0/agents/0x3f525572720361e3b750c9a29c9eb22e78eb3a8f' curl -s 'https://api.roundhouseai.io/v0/entities/0x3f525572720361e3b750c9a29c9eb22e78eb3a8f/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.
