## Tools (4)

- `check_brands`: Use this when the user asks whether a brand is reputable or what kind of brand it is (an established name, a store's own label, an independent maker, or a generic white-label name), or wants brands compared while shopping. Returns findings on each brand: what kind of brand it is, its reputation for quality and its usual price tier, each with a confidence. Signals only, never a buy or avoid verdict. Does not browse the web and is not for banking, health or email pages. Pass brand names as the user or the listing gave them, up to 50 per call.
- `check_product`: Use this when the user is looking at a specific product listing on an online store and wants to know whether it looks trustworthy or like a good buy. Pass what you already read from the listing as arguments: title (required) and, when shown, brand, price, listPrice (the seller's "was" price), currency, url, seller, category, rating, reviewCount and key details; each extra field sharpens the read. Returns findings such as generic white-label product, quality, price, questionable discount, review credibility and seller legitimacy, each with a confidence, plus a report on the brand unless includeBrand is false. Signals only, never a buy or avoid verdict. Does not browse: only the domain of url is used. Not for banking, health, government or email pages.
- `check_products`: Use this when the user is comparing several product listings, such as search results or the same item at different stores, and wants trust signals on each. Pass up to 20 products, each with what you already read from its listing: title (required) and, when shown, brand, price, listPrice, currency, url, seller, category, rating, reviewCount, details, plus your own id to match results. Returns, in input order, the same findings as check_product for each; a product that can't be checked carries an error and message instead. Signals only, never a buy or avoid verdict. Does not browse the web. Not for banking, health, government or email pages.
- `get_pro`: Returns a checkout link where the user can buy BuyWise Pro ($2.99/month plus any applicable tax, 3,000 checks a month, renewing monthly until cancelled), with the renewal terms and what happens after paying.
