Capabilities

Tools 4

find_cheapest

Find 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. Narrow it with filters (the category page's attribute filters, such as vegan or a form) and brand; every response lists the filters the category offers in available_filters.

Discovered
get_product

Get 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.

Discovered
list_categories

List 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.

Discovered
search_products

Search the whole supplement catalog the way the website's search box does. A product name or brand is matched typo-tolerantly (e.g. "kreatine", "theanin" still match). In markets where the site reads queries, a request described in words, with qualities (vegan, sugar-free, lab-tested, a form, a brand), is answered as that category with those filters, cheapest per unit first, and interpreted_as says how it was read and what could not be applied. Use find_cheapest instead when you already know the category.
