Why treg.to

Why call Coresignal through treg.to

No Coresignal 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

Charged per call. $1.00 free per new team, no card to start.

Your own Coresignal 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 Akta by Wokelo, Apollo.io, Aviato and ~2,600 other tools.

Questions

Before you start

Do I need a Coresignal 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 Coresignal 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 $0.392/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 Coresignal's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Coresignal to Claude Code?

Run: claude mcp add --transport http treg https://treg.to/mcp — one MCP server carries Coresignal 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 Coresignal MCP server?

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