Paid $1.30 of the $841.93M Roundhouse has indexed across 1,318,789 wallets — less than 0.0001% of it.

Counted from this wallet’s own settlements. The index rollup has no row for it yet, which is normal for an address first seen in the last half hour.

Chains (from the recent scan): Base (26)

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 catalogue100%$1.122412

$1.12 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: 0xfd7a…0181

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.
