Search for products on KuantoKusta.pt — Portugal's main price comparator.

Returns up to 48 products per page plus available_filters showing all filter options that can be applied to narrow the results. Filters are dynamic and change per product type — always read available_filters from the response rather than guessing values.

Recommended workflow:

1. Call search with just query (and optionally sort/price range).

2. Read available_filters in the response to see areas, brands, and product-specific filters (color, capacity, energy class, typology…).

3. Call search again with the desired filter values to get refined results.

Args: query: Search keywords, e.g. "frigorífico", "iphone 15", "tv 55 polegadas". area: Top-level category — use a value from available_filters where field="area". Example: "Electrodomésticos", "Informática". family: Sub-category within an area — use a value from available_filters where field="family". Example: "Grandes Electrodomésticos". sort: "cheap" (default) | "expensive" | "popular" | "alphabetical" | "newest". price_min: Minimum price in EUR (integer). price_max: Maximum price in EUR (integer). brands: List of brand names — use values from available_filters where field="brand". Example: ["Samsung", "LG"]. features: Dict of product-type-specific filter values — keys and valid values come from available_filters where field is NOT area/family/brand. Example: {"tipologia_s": "combinados", "cor_s": "inox", "classe_energetica_s": "classe a"}. For a laptop search the keys would be different (ram_s, os_s, etc.) — always derive them from the previous call's available_filters. page: Results page number (default 1; ~48 products per page).
