Over the whole indexed history

Paid $9.00 of the $260.88M Roundhouse has indexed across 716,644 wallets — less than 0.0001% of it.

Chains (from the recent scan): Base (3)

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	100%	$9.00	3	1

$9.00 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; no listed price matches an amount this agent paid, so nothing narrows them.

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: 0x3f55…c339

curl -s 'https://api.roundhouseai.io/v0/agents/0x3f55ad50f67050f8d925795bd4eb1523661ec339'

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,
