🔴check_store_prices(stores, query, limit)
Read an online store's products, prices and availability, and what changed since its previous daily snapshot. Use it for questions like "track competitor prices on allbirds.com", "what did gymshark.com change?", "did this store drop prices?", "what is new or sold out at this store?". Pass store web addresses, up to 5. Works for stores on Shopify that publish their public product feed (/products.json). The store is added to a daily snapshot list, so its history builds up. Optional filters: query (text in a product's title, brand or type), limit. Returns per store the snapshot date, product count, currency, counts and lists of new products, removed products, price changes and availability changes per variant, and matching products with price, variants and availability. The first snapshot of a store has no changes to compare with.

}🟢get_product_price_history(store, product)
Read how one product's price and availability moved over the days a store has been tracked. Use it for questions like "how has the price of this hoodie changed?", "when did this product go on sale?", "has this been out of stock?". Pass the store's web address and the product's link, handle or title (or part of it). Returns per variant the price, the compare-at (was) price and availability on each day something changed, from the first snapshot to now. History starts when the store was first tracked; a store never asked about before has a single snapshot. Several matching products come back as a list of titles to choose from.

}🟢compare_store_prices(source_store, target_store, query, match_by, min_gap_pct, ...)
Compare product prices between two online stores to find price gaps, spreads, and margin differences. Use it for questions like "compare prices between allbirds.com and allbirds.co.uk", "find the price gap for hoodies between two stores", or "which store sells this item cheaper?". Pass source_store and target_store web addresses. Supports cross-currency comparison: when stores quote in different currencies, prices are normalized using European Central Bank (ECB) daily reference rates via Frankfurter (https://api.frankfurter.dev, checked 2026-10-02). Optional filters: target_currency (defaults to target store currency), fx_rate (manual override), shipping_allowance (freight cost deduction), duty_allowance, include_landed_duty (EU flat customs duty), query (text in title/brand/category), match_by ("title", "sku", "handle", default "title"), and min_gap_pct (minimum percentage difference, default 0). Returns matched products with local and converted prices, exchange rate, rate date and source, price gaps, percentage spreads, stock availability, canonical links, and landed margin differences.

}🟡submit_feedback(kind, message, tool)
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
