Why treg.to

Why call Valyu through treg.to

No Valyu 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 Valyu 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 Context.dev, CoinGecko, Exa and 3,345 other tools.

Questions

Before you start

Do I need a Valyu account?

For 16 platform tools, no. The other 1 require your own Valyu key. All 17 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 $0.001/call. 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 Valyu's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Valyu to Claude Code?

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

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