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: ChainD - Web3 Services Marketplace (agent 51163 on eip155:8453)

curl -s 'https://api.roundhouseai.io/v0/agents/51163/feedback?chain=eip155%3A8453'
curl -s 'https://api.roundhouseai.io/v0/agents/0x7c655975fed04a1a27a87e4bf85d666a30bc1a30'

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.
