This is the foundation layer for crypto price data that ten other skills in the ecosystem depend on. It pulls real-time and historical prices for 10,000+ coins from CoinGecko with yfinance as fallback, handles rate limits intelligently with caching and exponential backoff, and gives you predefined watchlists for common categories like DeFi, layer 2s, and memecoins. The output flexibility is solid: formatted tables for quick checks, JSON for piping to other tools, or CSV exports for analysis. If you're building anything that needs crypto prices, portfolio tracking, tax reporting, or arbitrage scanning, this is your data layer. The auto-managed rate limiting and stale cache fallback mean it stays usable even when you hit API limits.
