All 4 Filtrat tools

People & contact data · 4 tools

Find a work email from a name and domain · Platform + BYOK · live-verified · $0.005/success
Find a person's work email from their name and company domain, verified against the mail server. filtrat.people.email.find
credits_used settles the call. A found address reduced the balance by exactly twenty credits; a deliberate miss (a person who doesn't exist) answered not_found in 3.7 s and reduced it by nothing.
Find a work email and resolve a catch-all domain · Platform + BYOK · live-verified · $0.00625/success
Find a person's work email; on a catch-all domain the address is resolved to a confirmed one. filtrat.people.email.find.resolve_catchall
credits_used settles the call. A find that needed catch-all resolution reduced the balance by 25 credits; the same person found again without needing it reduced it by 20. Misses are free.
Verify an email address · Platform + BYOK · live-verified · $0.00025/success
Check whether an email address is deliverable, with the domain's mail setup and catch-all detection. filtrat.people.email.verify
credits_used settles the call. A verified and an invalid address each reduced the balance by exactly one credit; catchall, risky and unknown answers report 0.
Verify an email address and resolve a catch-all domain · Platform + BYOK · live-verified · $0.00125/success
Verify an address and, on a catch-all domain, resolve it to deliverable or bounce. filtrat.people.email.verify.resolve_catchall
credits_used settles the call. A catch-all address resolved to verified reduced the balance by exactly five credits (catchall_resolved: true).

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 Filtrat 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 Filtrat 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 $0.00025/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 Filtrat's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Filtrat to Claude Code?

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

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