Yahoo Finance

This wraps the yfinance Python library in a clean CLI that pulls stock data from Yahoo Finance without needing API keys. You get price checks, fundamentals, earnings dates, options chains, analyst ratings, and dividend info for US stocks, Indian markets, crypto, and forex. It uses uv for dependency management with PEP 723 inline metadata, so first run takes a few seconds to cache dependencies, then it's instant. The compare command is handy for putting multiple tickers side by side. Good for quick terminal lookups when you don't want to open a browser or deal with API rate limits and tokens.

Yahoo Finance CLI

A Python CLI for fetching comprehensive stock data from Yahoo Finance using yfinance.

Requirements

Python 3.11+
uv (for inline script dependencies)

Installing uv

The script requires uv - an extremely fast Python package manager. Check if it's installed:

uv --version

If not installed, install it using one of these methods:

macOS / Linux

curl -LsSf https://astral.sh/uv/install.sh | sh

macOS (Homebrew)

brew install uv

Windows

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

pip (any platform)

pip install uv

After installation, restart your terminal or run:

source ~/.bashrc  # or ~/.zshrc on macOS

Installation

The yf script uses PEP 723 inline script metadata - dependencies are auto-installed on first run.

# Make executable
chmod +x /path/to/skills/yahoo-finance/yf

# Optionally symlink to PATH for global access
ln -sf /path/to/skills/yahoo-finance/yf /usr/local/bin/yf

First run will install dependencies (yfinance, rich) to uv's cache. Subsequent runs are instant.
