Amazon Sales Rank Tracker API - BSR Monitoring by ASIN

product

One Amazon product page, read in full and returned as one row: title, brand, the price and currency actually shown on the marketplace you asked for, list price and discount, coupon and deal badge, availability, the Buy Box seller with its id and whether Amazon fulfils it, delivery date, star rating with the 5-to-1 star breakdown and ratings count, bought-in-past-month, bullet points, description, every gallery image, variant ASINs with their named dimensions, breadcrumb categories, Best Sellers Rank in every listed category, date first available, manufacturer, model number, dimensions, weight and the whole product-details table. Billed once per ASIN per marketplace per run, however many inputs reach it. In monitoring mode a re-run bills a product only when a watched field - price, availability, sales rank, Buy Box seller by default - has changed since the last run; an unchanged product comes back as a free row. A product that cannot be read costs nothing and returns a free error row instead. Coverage rows, error rows and the run summary are free, and there is no run-start fee. Priced above the category on purpose: every product page is read from inside the marketplace's own country so the price is in its own currency - the unblocking that makes that possible is most of what a row costs to serve - and each row carries the Best Sellers Rank, the star breakdown and the Buy Box seller that cheaper scrapers leave empty. There is no captcha solver to buy on top.
