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":"a413a840ae59061b-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: 0xb1b1…214a

curl -s 'https://api.roundhouseai.io/v0/agents/0xb1b18d81660a16b75bd04beede8f2019a764214a'

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.
