  • search_products Searches 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, and several identifiers
  • semantic_search Searches WEM's partner-feed 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 the description is a product identifier (a barcode, ASIN, MPN, merchant SKU or wem3.ai/pl URL), that product is looked up inst
  • get_categories Lists 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). Use it to help a sh
  • get_product 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 source has them); when the source cannot be reached it falls back to WEM's catalogue r
  • compare_products Lays 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 `product_id`. Listings
  • find_lowest_price Picks 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-stock listing or one pri
  • compare_offers Lists the retailer offers WEM's catalogue holds for one product, current prices first and each group cheapest first, with WEM's 90-day price low (null when the product is held only in another currency). The product is found by barcode, catalogue slug or wem3.ai/pl/ URL, WEM ID, or a title (a model n
  • verify_offer 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 observed offer. Identify the product by gtin (strongest), slug, wem_id, provider + externalId, or title (we
  • lookup_products Looks 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 in the shopper's curre
  • get_evidence_receipt Fetches 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 `signed` true and an HMAC
  • search_promotions Lists 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 a discount on a produ
