Paid $0.00 of the $259.50M Roundhouse has indexed across 714,807 wallets.
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.
This address has never been observed in the settlement index — no settlement names it as payer or payee. Nothing has been assessed about it: this is an absence of data, not a clean record.

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: 0x3921c87c91801c3c56e9f802b736776e87e07fbf curl -s 'https://api.roundhouseai.io/v0/agents/0x3921c87c91801c3c56e9f802b736776e87e07fbf' curl -s 'https://api.roundhouseai.io/v0/entities/0x3921c87c91801c3c56e9f802b736776e87e07fbf/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. 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.
