Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check what 0xef87…5e06 has actually paid for over the free read API. No key, no account.

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: 0xef87…5e06

curl -s 'https://api.roundhouseai.io/v0/agents/0xef879bfd6c4accb8f795136de90246e1ec245e06'
curl -s 'https://api.roundhouseai.io/v0/entities/0xef879bfd6c4accb8f795136de90246e1ec245e06/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.
