HaulMath

Use this when the user wants to compare two package prices for the same product, including different unit sizes and the share they expect to use. Computes unit prices and the lower cost before and after expected waste. Inputs are processed temporarily and not stored by this service. It does not retrieve prices, compare quality, convert currencies or make purchases.

compare_bulk_prices

Compare user-supplied package quotes from up to six wholesale, bulk or regular retailers for one shopping list of up to eight slots. Each slot must use one caller-selected same product or explicitly acceptable alternative per store. Buy enough whole packages for the required usable quantity, then add known fees. Show missing items and membership exclusions; rank complete eligible baskets separately by tax-included versus pretax quotes. This tool does not retrieve retailer prices, infer product equivalence, verify stock, optimize substitutions or find the cheapest store globally. Inputs are temporary and not stored; do not provide receipts or personal account data.

compare_retailer_baskets

Find up to ten global community product records by name through Open Prices. Use this to discover product names, brands, package metadata and barcodes before selecting a product or an acceptable alternative. Results are name matches, not guaranteed grocery-category matches, US availability, equivalent products, dietary suitability or current prices. Similar names can refer to different products. Confirm the exact variant and package with the user, then use lookup_grocery_prices on a selected barcode. Product-name queries are sent to Open Prices and are not stored by this service; send product names only.

search_grocery_products

Open HaulMath's interactive workspace when the user wants to enter inputs, compare results, or work beside the conversation. This opens the interface without executing a data task.

open_app

Look up one selected grocery barcode in Open Prices. Returns at most ten US/USD community shelf-label observations from the past 30 UTC calendar days, with store, city, observation date, source link, price basis and discount indicators. This is incomplete community coverage, not a live retailer catalog, stock check, local-store search or guaranteed current checkout price. Empty results mean no matching observations in the bounded lookup. Never treat UNSPECIFIED pricePer as a package total or ignore discount/membership conditions. Confirm package quantity and price basis before using an observation for math; calculator quotes must be user-confirmed. Barcode is sent to Open Prices; no receipts, account data or location inputs are accepted or stored. Preserve source attribution when presenting results.
