Where Amazon seller intelligence breaks down
Three questions your own seller reports do not answer.
- Your shareThe only Buy Box history in your seller reports
You can't see who holds the Buy Box
The Buy Box moves between sellers on competitive ASINs. Your seller reports show your own share, not which competitor won it, when or at what price.
- LateWhen a rank change gets seen without saved checks
Rank moves and you see it late
Your listing can sit at position 4 on Monday and position 19 on Thursday. Without a saved check per keyword and per category, you find out when sales have already dropped.
- A nameWhat a listing tells you about a seller
You don't know who the other sellers are
An offer shows a seller name and little else. To decide what to do about a new seller on your listing, you need the business behind the name.
What Scrapewise does for Amazon sellers
Three things: Buy Box and offers, ranks, and seller profiles.
Buy Box and every offer per ASIN
The Amazon offers API returns one row per seller offer on a listing: price, shipping, condition, FBA flag and a true/false column for the Buy Box winner. One call returns about 10 offers and costs €0.00015.
Best Sellers Rank and keyword rank
The Best Sellers API returns a category chart as 50 ranked rows per call. The search API returns about 48 products per keyword with position and a sponsored flag. The product data API adds one ASIN's rank in each of its categories.
Seller profiles
The seller lookup returns what each seller published on Amazon: business name and address, and on EU marketplaces also email, phone and VAT number where the seller published them. A field the seller left out stays empty.
How a seller gets to a ready comparison
Four steps from a list of ASINs to one table.
- 01
Scrape: save your ASINs, keywords and categories
Paste the product, search, Best Sellers or seller links you care about. Run them once or on a schedule. Daily is the shortest.
- 02
Clean: prices and ranks as numbers
Price, shipping cost, position and rank arrive in their own columns, with the currency next to the amount.
- 03
Match: join everything on the ASIN
Offer, search and chart rows carry the ASIN, and every offer row carries the seller ID. To line them up with your own SKU list, use product matching.
- 04
Ready comparison: one table per question
Who holds the Buy Box on each ASIN, where each product ranks, and who each seller is. Every run is saved, so you can compare today with last week in the table, in Excel or through the API.

Buy Box Data on Your Schedule
Seller and price data from the listing itself, for the ASINs you choose, daily or on demand.
Ranks You Can Compare Over Time
Category ranks and keyword positions are saved for every run, so you see how a product's rank moves from one run to the next.

Frequently Asked Questions
Common questions from Amazon sellers and marketplace teams.
It is the public data around your listings that your own seller reports do not show: who holds the Buy Box, what every other seller charges, where products rank in a category and for a keyword, and who the sellers are. Scrapewise returns it as rows from six Amazon APIs at €0.00015 per call.
