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: 0x121c…d2d3 curl -s 'https://api.roundhouseai.io/v0/agents/0x121cdcca1bb3a5efd79d3c09ffdda3d48b99d2d3' curl -s 'https://api.roundhouseai.io/v0/entities/0x121cdcca1bb3a5efd79d3c09ffdda3d48b99d2d3/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.
