Paid $9.55 of the $834.10M Roundhouse has indexed across 1,300,498 wallets — less than 0.0001% of it.

Chains (from the recent scan): Base (200)

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.

GroupShareSpentCallsSellers
Web & Content65%$6.18654
Not in any catalogue35%$3.301125
Crypto Markets<1%$0.0572
Location & Weather<1%$0.00841

$1.51 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.

One merchant publishes more endpoints than a single catalogue read returns; its list is partial.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check what 0x4b02…d9ef has actually paid for over the free read API. No key, no account.

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: 0x4b02…d9ef

curl -s 'https://api.roundhouseai.io/v0/agents/0x4b02f8b83afbe346ce47a1bc8cb40a1e2bacd9ef'
curl -s 'https://api.roundhouseai.io/v0/entities/0x4b02f8b83afbe346ce47a1bc8cb40a1e2bacd9ef/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.
