Sweeping the chain

We hold no settlements for this wallet. That is not the same as it having none, so we are looking: Queued. A worker will pick this up in a few seconds.

Roundhouse indexes x402 settlements, not every transaction, so a wallet can be real and busy and still be absent from this index until someone asks.

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: 0xfe90787f976f145059a8fce71d99a006a209fc48

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
