Connects to eBay's API for real-time pricing data and Ball Don't Lie for NBA stats, plus NFL and MLB player data. You get nine tools covering price lookups, market trend analysis with arbitrage detection, grading ROI calculations for PSA/BGS/SGC, and player performance tracking across basketball, football, and baseball. The vintage card analysis covers 40+ sets from 1909 T206 through 2000 Playoff Contenders with grade-specific pricing. Useful if you're building card collecting tools, investment dashboards, or just need to answer "should I grade this card" without manually cross-referencing eBay sold listings against grading fees. Works with mock data out of the box, but you'll want the free API keys for production use.
