"description": "Search canonical products with category, attribute, price, provider, vendor, sorting, and bounded pagination filters. Attribute pairs are forwarded to supplier discovery as provider Pid/Vid filters when expansion is needed, so keep the exact attributeId/valueId returned by facets. When the shopper requests N products, set limit=N (1–48); leave it unset to use the default of 12 when no count is specified. Set compact=true when limit exceeds 24; compact changes card payload size, not card selection. The product-card UI displays every returned item and supplier preview, up to 24 cards per result. Do not fetch a larger page and then select fewer only in prose: those returned cards still appear in the UI. If the shopper wants only the existing catalog or says not to search suppliers, set expandSuppliers=false so previews are not added. When product-card UI is attached, do not claim product photos are unavailable solely because the text response lacks inline images; refer to the rendered cards. Set freshOnly=true to exclude products already opened or explicitly exposed to this shopper. Use nextCursor for stable exploration pages, or nextOffset when nextCursor is unavailable; keep using the same query and filters. If status is pending, wait until retryAfter and resume with nextCursor as cursor, or nextOffset as offset when no cursor is returned; never restart a pending search from the first page. Supplier discovery automatically runs in the background for missing, weak, or exhausted results unless expandSuppliers=false. A broad result withholds unconfirmed canonical cards and describes only the current page. Continue with nextCursor when present, otherwise nextOffset; zero supplier previews on a page does not mean the search is exhausted. If supplierExpansion is queued, running, or throttled, wait until supplierRetryAt and repeat the same search. If supplierExpansion is failed, stop retrying that supplier search, report the returned failure classification, and continue only with other available results or a materially different shopper request. Set waitForSupplierResults=true to have the server poll a queued supplier expansion for up to maxWaitMs before returning.",
