Using Roundhouse, vet this ERC-8004 agent identity for me: what does its card claim, who has rated it, and does its on-chain record support the claim? Identity: Silverback (agent 1156 on eip155:8453) curl -s 'https://www.roundhouse.studio/api/v0/agents/1156/feedback?chain=eip155%3A8453' curl -s 'https://www.roundhouse.studio/api/v0/agents/0xd34411a70effbdd000c529bbf572082ffdcf1794' curl -s 'https://www.roundhouse.studio/api/v0/entities/0xd34411a70effbdd000c529bbf572082ffdcf1794/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. If you do not have Roundhouse tools or skills installed, read https://www.roundhouse.studio/skill.md first — it is the whole procedure, and it needs no key.
