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: 0x3921…a6fb curl -s 'https://api.roundhouseai.io/v0/agents/0x3921d3968634f54702e428399ff4742811dca6fb' curl -s 'https://api.roundhouseai.io/v0/entities/0x3921d3968634f54702e428399ff4742811dca6fb/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.
