Deal Discovery

Deal discovery is the process of identifying products currently available at a discount relative to their typical or reference price. Deal discovery tools aggregate current prices, compare them against historical prices or MSRP, and surface products where the discount exceeds a threshold.

APIs with dedicated deal endpoints - like the Klarna Ecom /deals endpoint or Kohls' /product-search with sale filters - expose currently discounted products directly, eliminating the need to independently calculate discounts from raw pricing data.

The freshness of deal data is critical - a deal that sold out an hour ago will lead to disappointed users. Real-time or near-real-time data is a hard requirement for any product in the deal discovery space.
