find_cheapestread-onlyFind the cheapest supplements by normalized price-per-unit within a category (and all its subcategories). This is the primary tool for "what is the cheapest X?" questions. Use list_categories first to pick a valid category_slug.
search_productsread-onlySearch the whole supplement catalog by product name or brand. Typo-tolerant (e.g. "kreatine", "theanin" still match). Results are ordered by relevance, then cheapest normalized price-per-unit. Use find_cheapest instead when you already know the category.
list_categoriesread-onlyList the supplement categories that currently hold priced products, each with a live product count, store count, lowest normalized unit price, and its comparison basis (per_kg / per_serving / per_capsule). Use this to discover a valid category_slug for find_cheapest.
get_productread-onlyGet full detail for one product by its id: price, normalized unit price, size, bulk/staffel tiers, buy link, and recent price history. Use the id returned by find_cheapest or search_products.
