Over the whole indexed history

Paid $43.88 of the $3059.84M Roundhouse has indexed across 1,397,496 wallets — less than 0.0001% of it.

Chains (from the recent scan): Base (232)

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
Not in any catalogue79%$34.78806
Location & Weather21%$9.091511
Web & Content<1%$0.0111

$9.06 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 4 of 8 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: 0x739c…87bb

curl -s 'https://api.roundhouseai.io/v0/agents/0x739c393ccb9a42e0f94a3b433b8b3df9794087bb'
curl -s 'https://api.roundhouseai.io/v0/entities/0x739c393ccb9a42e0f94a3b433b8b3df9794087bb/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.
