# FinzData skill for Claude

Source: https://finzdata.com/skills/

Install the FinzData skill in Claude.ai or Claude Code: point-in-time market data, GEX, futures, COT and macro for backtests.

A ready-made [SKILL.md](https://finzdata.com/skills/finzdata/SKILL.md) that teaches Claude (Claude.ai, Claude Code and the Agent SDK) when and how to use FinzData: which tool answers which question, how to avoid look-ahead bias with `as_of`, and what the free tier covers.

## Install

- **Claude.ai:** download [finzdata.zip](https://finzdata.com/skills/finzdata.zip) and upload it under Skills in Claude.ai settings.

- **Claude Code:** `mkdir -p ~/.claude/skills/finzdata && curl -s https://finzdata.com/skills/finzdata/SKILL.md -o ~/.claude/skills/finzdata/SKILL.md`

- **Connector:** `claude mcp add --transport http finzdata https://api.finzdata.com/mcp` (or add it from [finzdata.com/mcp](https://finzdata.com/mcp))

Then ask: "Using FinzData, what is the SPX gamma flip today?" or "Backtest a 12-month momentum strategy on survivorship-free S&P 500 data."
