  • Find email addresses at a company domain, with roles · Platform + BYOK · live-verified · $0.0245/started 10 emails
    People and email addresses Hunter knows at a company, with roles and confidence. DELIVERABILITY WARNING: this is a directory listing, not a verified list — each row's `verification.status` is null unless Hunter has checked that mailbox, and `confidence` below ~50 is a pattern guess. Live 2026-09-08, a team that mailed generic rows (info@, sales@) straight from this endpoint bounced on 73 of 79; a hunter.people.email.verify call per address ($0.012, or leadmagic.people.email.verify at $0.006) would have caught all 73. Verify before outreach, and never invent info@ for a domain this returned nothing for. hunter.companies.emails
    1 SEARCH credit per 10 emails returned (rounded up); a domain with no results is free. OBSERVED 2026-07-31 — a `limit` of 1 on a domain never queried on this key returned 1 email and moved requests.credits.used by exactly 1.000, confirming the per-10 rounding — one email costs the same whole credit as ten, so a limit below 10 buys nothing.

Questions

Before you start

Do I need a Hunter account?

For 12 platform tools, no. The other 23 require your own Hunter key. All 35 accept your own key, and treg never meters BYOK calls.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.0245/started 10 emails. The rate is the provider's own and treg.to adds no markup; it is billed per call from a prepaid balance. It is not Hunter's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Hunter to Claude Code?

Run: claude mcp add --transport http treg https://treg.tracea.online/mcp. One MCP server carries Hunter and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Hunter MCP server?

No. treg.to serves Hunter's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Hunter channels are linked above.
