🚀 Quick Start

Just want to run it:

pip install investormate
investormate quote AAPL          # live price snapshot — no API key
investormate analyze MSFT        # fundamentals + key ratios
investormate analyze AAPL --json # machine-readable output for scripts

Or use the Python API (same package, no extra install for stock data):

from investormate import Stock

stock = Stock("AAPL")
print(f"Price: ${stock.price}")
print(f"P/E Ratio: {stock.ratios.pe}")
print(f"ROIC: {stock.ratios.roic}")  # Advanced ratios
print(f"TTM EPS: {stock.ratios.ttm_eps}")  # Trailing metrics
print(f"RSI: {stock.indicators.rsi()}")

# Batch load tickers (skips bad symbols with a warning)
stocks = Stock.batch(["AAPL", "MSFT", "GOOGL"], skip_invalid=True)

# Beneish detail (8 indices when statements allow)
detail = stock.scores.beneish_m_score_detail()
print(detail.get("indices"), detail.get("score"))

📦 Installation

# Basic installation (CLI + stock data — no API key required)
pip install investormate

# With AI providers (OpenAI / Anthropic / Gemini / OpenRouter SDKs)
pip install investormate[ai]

# With Excel export support
pip install investormate[export]

# Everything
pip install investormate[all]

# With development dependencies
pip install investormate[dev]

🔑 API Keys

Stock quotes and analysis work without any API keys. AI features need one provider key and the [ai] extra:

pip install investormate[ai]

• OpenAI: Get your API key at https://platform.openai.com/api-keys
• Anthropic Claude: Get your API key at https://console.anthropic.com/
• Google Gemini: Get your API key at https://ai.google.dev/
• OpenRouter: Get your API key at https://openrouter.ai/keys (one key → hundreds of models)

You only need one API key to use the AI features.

from investormate import Investor

# OpenRouter gives access to many models via a single key
investor = Investor(
    openrouter_api_key="sk-or-...",
    openrouter_model="anthropic/claude-3.5-sonnet",  # optional; defaults to openai/gpt-4o
)
result = investor.ask("AAPL", "Is Apple undervalued compared to its peers?")
