Calculates discounted prices from original amounts and percentage rates. Use via MCP in Cursor or Windsurf, or call GET /v1/finance/discount with original_price and discount_percentage parameters. Returns the final price after discount — if you pass $100 with 20% discount, you get $80. Essential for e-commerce calculations and financial modeling in AI agents.
