Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check whether Barker Yield Agent is backed by a real record over the free read API. No key, no account.
GET api.roundhouseai.io/v0/agents/52838/feedback?chain=eip155%3A8453
Resolved from Base registry 0x8004…a432. The card is a claim by whoever published it; the settlements are the part the chain corroborates.

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: Barker Yield Agent (agent 52838 on eip155:8453) curl -s 'https://api.roundhouseai.io/v0/agents/52838/feedback?chain=eip155%3A8453' curl -s 'https://api.roundhouseai.io/v0/agents/0xcd15d6c9af7639c7e5417d16bb12df2774ba7c09' curl -s 'https://api.roundhouseai.io/v0/entities/0xcd15d6c9af7639c7e5417d16bb12df2774ba7c09/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. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
