ZeroVaR

Build with the R&D API

Personal API keys, live FX endpoints, Google Sheets formulas, and Claude on the staging R&D API.

Get API key 5-minute quickstart

Each setup guide (Quickstart, Sheets, Excel, Claude, Auth) has a Copy for your LLM block for connecting. Project MCP (under Projects) is meant to sit in the chat where you already work — not a blank coach thread.

Get started

Google Sheets

Custom functions for spot, forward, vol, carry, and TCA. Paste Apps Script and go.

Excel

Windows VBA UDFs with the same ZV_* formulas and personal API key as Sheets.

Claude

claude.ai Connectors in a few clicks (no API key): spot, forward, vol, and carry from chat. Includes what Claude’s own usage limits mean vs ZeroVaR.
