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: 0x8f40…3090 curl -s 'https://api.roundhouseai.io/v0/agents/0x8f4073a2f6a275b7e879a6d4ad6b8196af6c3090' curl -s 'https://api.roundhouseai.io/v0/entities/0x8f4073a2f6a275b7e879a6d4ad6b8196af6c3090/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.
