Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check whether attester.dev is backed by a real record over the free read API. No key, no account.

GET api.roundhouseai.io/v0/agents/59492/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: attester.dev (agent 59492 on eip155:8453)

curl -s 'https://api.roundhouseai.io/v0/agents/59492/feedback?chain=eip155%3A8453'
curl -s 'https://api.roundhouseai.io/v0/agents/0x31520f9c14360470040807faba64938ebcff9c8f'

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.
