People & contact data · 2 tools

Find a work email from a name and domain · Platform + BYOK · live-verified · $0.276/success
Search for a person's business email in real time from their name and company domain zerobounce.people.email.find
20 PAYG credits or one subscription query per successful email; undetermined results are free. The account's first 10 successful Finder/Domain Search calls used a promotional allocation and left the PAYG balance unchanged; the next successful Email Finder call reduced the balance by exactly 20 credits.
Verify an email address · Platform + BYOK · live-verified · $0.0138/success
Check mailbox deliverability and risk status in real time zerobounce.people.email.verify
One purchased credit per non-unknown result at the supplied $69 / 5,000-credit replacement rate. Official docs say unknown results consume no credit. Two fresh live validations reduced the balance by exactly one credit each: an invalid mailbox from 5,098 to 5,097 and a valid mailbox from 5,097 to 5,096.

Company data · 1 tools

Find a company's email address patterns · Platform + BYOK · live-verified · $0.276/success
Detect the likely business-email formats used by a company domain, with confidence levels zerobounce.companies.email_pattern
20 PAYG credits or one subscription query per successful format; undetermined results are free. A live successful response used the shared 10-call promotional Finder/Domain Search allocation and left the PAYG balance unchanged. The 20-credit PAYG fallback was subsequently observed on Email Finder, which uses the same upstream route and shared allocation; this Domain Search price remains documented until its own paid result is observed.

Reliability badges come from live traffic through treg.to. Live-verified means a successful provider check; it does not verify every request variant.

Questions

Before you start

Do I need a ZeroBounce account?

No. Eligible tools run on treg.to's key and the call is metered from your team's prepaid balance, priced up front. If your team registers its own ZeroBounce key, that key always wins and those calls are never metered.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.0138/success. 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 ZeroBounce's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add ZeroBounce to Claude Code?

Run: claude mcp add --transport http treg https://treg.to/mcp. One MCP server carries ZeroBounce 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 ZeroBounce MCP server?

No. treg.to serves ZeroBounce'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 ZeroBounce channels are linked above.
