Why treg.to

Why call MillionVerifier through treg.to

No MillionVerifier signup

Eligible tools run on treg.to's key, metered per call from a prepaid balance.

Price before the call

The provider's own rate, $0.000 markup. How billing works.

No subscription, no seats

Platform calls are charged per call. $1.00 free per new team, no card to start.

Your own MillionVerifier key is free

Register it and those calls are never metered. Your key always wins.

Switch by changing a word

Another provider is a different word in the prompt, not a new integration.

One key, the whole catalog

The same token calls BounceBan, ContactOut, Dropleads and 3,279 other tools.

    One credit per verification at the $89 / 50,000-credit pack rate, including invalid results. Credits never expire. Upstream deducts a credit first, then automatically returns it for unknown/catch-all results on eligible accounts; accounts flagged for misuse may still pay. On platform keys, treg settles unknown/catch-all at zero without waiting for the upstream return and absorbs any eligibility exception. Own keys are not metered by treg. Credit returns were observed on the promotional account; the account owner confirmed a $89 purchase of the base 50,000-credit pack. This rate excludes the initial free credits and variable promotional bonuses; it is the documented base-pack rate, not the effective cost after bonuses.

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 MillionVerifier account?

For 1 platform tools, no. The other 1 require your own MillionVerifier key. All 2 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 $0.00178/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 MillionVerifier's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add MillionVerifier to Claude Code?

Run: claude mcp add --transport http treg https://treg.tracea.online/mcp. One MCP server carries MillionVerifier 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 MillionVerifier MCP server?

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