Where marketplace seller intelligence breaks down
Three structural gaps every Amazon/eBay seller eventually hits.
- Your shareThe only Buy Box history in your seller reports
You can't see who takes 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.
- PartialCompetitor detail in marketplace API data
Marketplace APIs show only part of the picture
Your repricer is fed by marketplace APIs built around your own listings. Detail on competing sellers is limited. Independent scraping fills the gap.
- WeeksTime before brand-violation flags surface
Account health degrades silently
Marketplaces flag restricted-brand violations weeks after they occur. Without seller-side monitoring, you find out when your account suspends.
What Scrapewise actually does for marketplace sellers
Three things, simply: independent Buy Box data, cross-marketplace coverage, and seller-level intelligence.
Independent Buy Box data
Scrapewise pulls the Buy Box winner and price on the ASINs you care about, on a daily schedule or on demand, and feeds your repricer through the REST API or a CSV export.
Cross-marketplace coverage in one schema
Amazon, eBay, Walmart, Etsy — same SKU, all in one structured table for true competitive visibility.
Seller-level + listing-level data
Output captures seller name, seller rating, FBA flag, stock level — not just price. Catch competitor seller patterns.
How a marketplace seller gets up and running
Five steps from blank canvas to Buy Box data flowing into your repricer.
- 01
List your ASINs / SKUs to monitor
Tell Scrapewise which products to track — by ASIN, GTIN, SKU, or marketplace listing URL.
- 02
Configure scrape templates
Tell Scrapewise which fields to extract — price, Buy Box winner, seller name, FBA flag, stock signal. No code.
- 03
Set the refresh schedule
Daily on hot ASINs, weekly on stable ones, plus on-demand runs. Start runs from your own code with a full-access API key when you need more.
- 04
Pipe into your repricer
REST API or CSV export. Feed Aura, RepricerExpress, BQool, or your in-house pricing logic.
- 05
Layer brand-protection scrapes
Add unauthorized seller monitoring on the same data infrastructure to protect your account health.
