Over the whole indexed history

Paid $0.02 of the $260.90M Roundhouse has indexed across 716,705 wallets — less than 0.0001% of it.

Chains (from the recent scan): Base (2)

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%	$0.02	2	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 1 of 1 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: 0xfff8…509c

curl -s 'https://api.roundhouseai.io/v0/agents/0xfff84441a3e8562cfff331f0078e457e25ac509c'

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.
