Lēta Pārtika

Compare one selected product across retailers and store locations. Use after search_groceries when the user wants to compare the same product, ask where it is cheapest near a city, or needs retailer-specific availability. If city is supplied, return only locations in that city; otherwise return up to five current locations per retailer.

get_product_prices

Get rich consumer details for one product already selected from search_groceries: image, package size, nutrition, ingredients, allergens, dietary flags, manufacturer, origin, and category. Use only when those details help answer the user’s question, such as comparing protein, checking allergens, or identifying the right product.

get_product_details

Estimate a personal grocery list of up to 12 simple items at current Latvian prices. Use when the user asks what their shopping list will cost or which store is cheapest for it. Use only for a concrete shopping list, not recipes, menus, or catalogue research.

quote_shopping_list

Search current grocery products for a consumer. Use this for discovery and all product-price questions, including “cheapest” and “lowest price”; set sort to "price_asc" for the cheapest item price or "unit_price_asc" for the best value by unit. Results include an image, current price, unit price, and product page link.

search_groceries

Show the itemized winning basket and up to three already-calculated store options. Use after quote_shopping_list when a visual basket helps the consumer review matched items and compare totals. Pass through each option and its items exactly as returned; do not recalculate or rematch anything.

render_basket

Show up to 10 already-selected grocery listings as compact Lēta Pārtika product cards. Use after search_groceries when a visual comparison helps the consumer choose. Do not use for more searching or to change prices.
