How this service works
Amazon price history API: full product data for 1-100 ASINs. Complete Amazon price history and sales-rank history (full tracked history) plus current prices, buy box, live offers and stock, ratings history, monthly sales, variations, dimensions and fees for 1-100 ASINs (or UPC/EAN) per call. Clean JSON with ISO dates. From $0.005 per product; options like offers and buybox add credits. Use history=0 for current data only. Free sample: /api/sample/data-product
Output
A JSON object containing a products array where each element includes: ASIN, title, brand, manufacturer, images, categories, price history time series by series type (BUY_BOX_SHIPPING, AMAZON, NEW, USED, SALES_RANK, etc.), current buy box price, statistics (min/max/average over a date window), monthly sold estimate, FBA pick-and-pack fees, referral fee percentage, out-of-stock percentages, live offers (optional), ratings and review count history (optional), package dimensions, and marketplace metadata. Also includes _meta with cache status, price paid, and marketplace domain ID.
Example use cases
FBA product research before sourcing
“I'm thinking about selling ASIN 0735211299 on Amazon FBA — can you get me the full price history, monthly sales estimate, FBA fees, and current buy box price for it on the US marketplace?”
Price drop alert investigation
“I noticed a competitor's price changed — can you pull the last 30 days of buy box price history and current live offers for ASINs B09G9FPHY6 and B07XJ8C8F5 on Amazon US so I can see what happened?”
Barcode to Amazon product data lookup
“I have a UPC code 012345678901 — can you look it up on Amazon and give me the current price, sales rank, ratings history, and product details?”
Technical details
Endpoint
GEThttps://asin402.com/api/data/product?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive Amazon product intelligence — especially historical price and sales rank data — for 1 to 100 products in a single call. It is ideal for FBA sellers doing product research, price monitoring systems, competitive analysis tools, and any workflow that needs structured historical time series with ISO dates in clean JSON. Prefer it over single-ASIN endpoints when batching is needed, and over scraping when you need structured, reliable, long-horizon history.
Side effects
- Invalid or non-existent ASIN returns empty products array or error
- Exceeding 100 ASINs per call returns validation error
- Using both asin and code parameters simultaneously returns error
- Unsupported marketplace domain returns error
- Offers fetch timeout (2–20 seconds) may result in partial data
- Insufficient credits for add-on features (buybox, offers, rating, stock) returns error
- UPC/EAN with no Amazon match returns empty result
