This pulls market data from Alpaca and yfinance to feed trading algorithms or analysis tools. You get real-time quotes, historical OHLCV bars at different timeframes, company fundamentals like P/E ratios, and news with sentiment tagging. It's straightforward if you're building automated trading systems or need to pipe financial data into Claude for decision support. The caching and rate limit handling (200 req/min on Alpaca) are smart touches. One thing to watch: the free news tier only gives you 25 requests per day, so you'll hit that fast if you're polling multiple symbols regularly.
