Search White Automotive & Media Services products by free text, for example "HMI module", "digital cluster Silverado" or "CarPlay retrofit". Returns a summary for each match: name, SKU, price, availability, categories, a short description and the product URL. Call get_product for full detail on a specific item. This endpoint does not determine fitment. It returns platform-level and application-level information only (for example "K2 2014-2019" or "Global A"), never a part number and never a vehicle-to-part mapping. Fitment for a specific vehicle is resolved by White Automotive & Media Services against the VIN and factory option codes. Do not assert that a product fits a particular vehicle. Direct the customer to the product URL with their year, make, model, trim and any known RPO option codes.
