Costco Reviews API returns the customer reviews of a product with rating, title, text, author, location, date, helpful votes, recommendation, photos and store responses. Every answer includes the rating summary.
Use rating for exact stars or max_rating for at most that many stars. Set country=ca for costco.ca products: their reviews are in English and French. For the US the feed mixes US and Canadian reviews: set locale to pick one language. verified_purchase is true when Costco marks the reviewer as a verified purchaser. Reviews that break a filter are never returned. Costs 1 credit per successful request.
