Over the whole indexed history

Paid $0.20 of the $846.70M Roundhouse has indexed across 1,330,126 wallets — less than 0.0001% of it.

Chains (from the recent scan): Base (4)

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
Crypto Markets	100%	$0.20	4	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.

The transfer history behind this wallet was not read (explorer HTTP 403), so where its funds came from is unknown here. The balance above is still measured.

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: 0x51b6…d21d

curl -s 'https://api.roundhouseai.io/v0/agents/0x51b62bdefb4ee0c5ac1d21b1a4376a23b627d21d'
curl -s 'https://api.roundhouseai.io/v0/entities/0x51b62bdefb4ee0c5ac1d21b1a4376a23b627d21d/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.
