search_productsSearches WEM's catalogue and its connected retailer sources for products matching a query. The query can be a product name or an identifier: a barcode (EAN/UPC/GTIN), an Amazon ASIN, an MPN, a merchant SKU that names one catalogue product, a WEM ID or a wem3.ai/pl/{slug} URL, an…
semantic_searchSearches WEM's products by meaning, for a plain-language need such as "comfortable shoes for standing all day" or "gift for a 10 year old who likes science". If vector ranking is unavailable or has no safe match, it falls back to keyword search across WEM's catalogue and connect…
get_categoriesLists the six broad shopping categories WEM covers (electronics, fashion, beauty, home, sports, collectibles), each with example products, the shops WEM has read a price from in the last 14 days (busiest first, with how many shops there are in all) and the default currency (GBP)…
get_productProvide at least one of: wem_id, or provider and product_id. Returns one product's details. Given `provider` and `product_id` from a search result, it returns that listing as its retailer source supplies it (title, price and link, with rating, shipping or features where the sour…
compare_productsLays 2 to 5 listings from earlier search results side by side in `comparison`: each listing's price and currency, and its rating, shipping and features where the retailer source supplies them (many listings carry none). Each item needs the listing's `provider` and its `id` as `p…
find_lowest_pricePicks one listing for a kind of product within the shopper's constraints, from WEM's catalogue and a live retailer search (a current catalogue match answers without the live search). Candidates are first filtered to plausible matches, so an accessory, another size, an out-of-sto…
compare_offersProvide at least one of: gtin, slug, wem_id, or title. Lists the retailer offers WEM's catalogue holds for one product: available current prices cheapest first, then current offers last seen out of stock and older prices, with WEM's 90-day price low (null when the product is hel…
verify_offerProvide at least one of: gtin, slug, wem_id, provider and externalId, or title. Checks a price someone has claimed for a product against the prices WEM has itself observed at retailers (recent readings, within a small tolerance; not a live quote), and reports the cheapest observ…
lookup_productsLooks up to 20 product identifiers in one call: barcodes (EAN/UPC/GTIN), Amazon ASINs, WEM IDs, catalogue slugs or wem3.ai/pl URLs. Each row has a status: found (WEM's catalogue holds it; the row gives its number of retailer offers, the lowest current price at a named retailer i…
get_evidence_receiptFetches an evidence receipt by its id (wem-evr- followed by 32 hex characters), as issued with a verify_offer result. Returns the receipt's fields: verdict, observed_at, source, amount, currency and amount_minor, identity_method, verifier, standardVersion and issuedAt, with `sig…
search_promotionsLists current promotions (sales and offers) that retailers in WEM's Awin affiliate programmes have published, for the shopper's market. Filter by merchant or by words in the offer. Each row gives the offer, its dates and a tracked link. A promotion is not a price, and it is not…
