How this service works
Get Amazon Best Sellers for a category on any Amazon marketplace (amazon.com, amazon.de, amazon.co.uk, amazon.co.jp and more): ranked products with ASIN, title, brand, price, rating, reviews, Best Sellers Rank, seller and image. Async: first call with category_url returns a snapshot id; call again with that snapshot to fetch the ranked list. For cross-market trend spotting and product selection. 亚马逊各国站畅销榜选品。
Output
An async two-step response: the first call returns a snapshot ID and status 'pending'; calling again with the snapshot ID returns status 'ready' plus an array of ranked products, each with ASIN, title, brand, price, star rating, review count, Best Sellers Rank, units bought in the past month, seller name, number of sellers, product URL, and image URL, along with a count and source label.

GEThttps://api.cn402.com/ecom/bestsellersWhen to prefer
Use this endpoint when you need structured Amazon Best Sellers data for a specific category, including BSR, pricing, brand, and seller metadata, especially for product selection, niche research, or demand validation workflows. Prefer it over manual scraping or generic e-commerce APIs when you need ranked product snapshots with rich seller context from Amazon's live catalog.
