Let your AI agent build prospect lists at any company. Search decision-makers by title, domain, or LinkedIn URL, verify business emails, and pull firmographics. Pay per call from your workflow wallet (~$0.005) — only when your agent runs on live data. • 7 tools: people + company search/enrich, email find/verify, premium contact enrich • Under the hood: Apollo, Hunter, Clado • Works in Claude Code, Cursor, Codex, or any MCP client • Free demo mode always-on: every tool returns a cached PII-reduced preview with no upstream payment. Pass `demo: false` and pay via x402 to unlock live data.

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: B2B Contact Intel API (agent 45247 on eip155:8453)

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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.
