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%	$0.001	1	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.

Inflows and outflows

Every token transfer this wallet has made, not just the x402 ones the index holds.

The transfer history behind this wallet was not read (cdp sql 429: {"correlationId":"a4024a0dde1b29be-IAD","errorLink":"https://docs.cdp.coinbase.com/api-reference/v2/errors#rate-limit-exceeded","errorMessage":"Rate limit exceeded. Please try again in a few seconds."), 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: 0xfb5c…3881

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.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
