## When to prefer this

Use this endpoint when you need to search Walmart's product catalog by keyword, especially when you want to filter by price range, sort results, or target a specific store or zip code. Prefer this over the category-browse endpoint when you have a specific product keyword in mind rather than a category to browse.
