Watch Amazon ASINs: scheduled price, buy box and stock checks with change alerts...
https://asin402.com/api/watchOverview
Watch Amazon ASINs: scheduled price, buy box and stock checks with change alerts. Pay once to monitor 1-50 ASINs every 1h, 3h, 6h, 12h or 24h for 1-30 days. Each check records buy box, Amazon, lowest new/used price, stock, buy box seller, offer count, sales rank and rating, and logs changes as events (price drops/rises, out of stock, back in stock, buy box seller change, below your target price). Poll the free status URL with your watch key to read new events. The first check runs immediately. P
