Price the same product at several stores — up to 5 URLs in ONE call and ONE payment. USE THIS WHENEVER YOU HAVE MORE THAN ONE URL. Comparing an item across stores, checking a short list, or refreshing a handful of tracked prices. It returns full details for each URL so YOU can compare them; it does not rank them or pick a winner. Through get_product_details that is one EIP-3009 signature, one settlement and one round trip PER URL; this is one of each for the whole set. RETURNS one entry per URL in the order given, each with the same product and page objects get_product_details returns, plus ok/error so a single dead URL does not cost you the rest. COST $0.15 flat for up to 5 URLs — cheaper per page than calling get_product_details 5 times. BILLING, stated plainly: the price is flat, so a batch where only SOME URLs succeed is charged in full. A batch where NO url succeeds returns an error and is not charged. If you have one URL and are unsure it is live, get_product_details is the cheaper bet. Duplicate URLs are removed and not billed twice.
