Use cases

• ASIN lookup — Turn a product name into an ASIN.
• Product pickers — Let users search Amazon from your app, then track what they choose.

Why Asin?

• Price history for any ASIN — read every price Asin has seen, free and without tracking the product.
• Alerts by email — price drops, target prices and products back in stock.
• Pay for what you check — each price check costs 1 credit (about 30 credits a month for a product checked daily) and failed checks are refunded. Free for 50 products.
• Use it your way — the same API key works with the REST API, the MCP server and the Chrome extension, with official SDKs in 7 languages.
• Copy-paste examples — Python and TypeScript in each README, 7 more languages in examples/.
