Analyze supplier files
in minutes, not hours
Scan millions of products to find profitable wholesale opportunities for your Amazon FBA or FBM business.
Put your supplier catalogs on autopilot
Stop uploading the same supplier files every week. Send your catalogs through the Rocket Source API on your own schedule and get profit, fees, and price history back for every row.
Built for supplier lists with thousands to millions of rows, not one-product-at-a-time lookups.
API first
Scans, results, and exports all run through the API. Hand our docs to Claude or Codex and let them wire it into your workflow, or call it from your own scripts.
No Amazon integration to build
API approval, rate limits, and fee quirks are already handled. One API key gives you the same data points as the web app.
Trust the average, not the spike
30 and 90 day price averages, sales rank history, and in-stock rates in every row, so one price spike doesn't fool your buying rules.

From supplier file to buy list
in three steps
Works with the price lists your suppliers already send you.
Upload any supplier file
CSV or XLSX, messy columns and all. UPCs, EANs, ISBNs, and ASINs are matched, with identifier and multipack correction built in.
See profit, fees, and history per row
Profit after fees, restrictions and eligibility checks, competition, and 30 and 90 day price history for every product in the file.
Filter down to your buy list
Save your filters and layouts, load them in one click, and export the winners to Google Sheets, CSV, or XLSX.
Doing this every week? Skip the upload and run it through the API.

Scan 6 million products
per hour
Fast enough to re-check your whole supplier catalog as often as prices change, not once a month.
Profitability, demand,
and competition data
Calculate ROI, estimate monthly sales, and see seller counts, all before you place an order.
Never repeat yourself
Notes, blocklists, and corrections carry into every future scan, whether you upload the file or your script sends it. You never clean up the same supplier list twice.
Remember why you passed
Notes stay on the product, so next month's scan shows “MAP issue, skip” before you spend time on it again.
Never see a gated brand again
Add a brand or ASIN to your blocklist once, and it's filtered out of every scan after that.
Correct a pack size once
When Amazon lists a 6-pack as a single, fix it once and every future scan uses your number.
Correct a listing match once
Mark whether a barcode and ASIN really match. It's automatically applied to all future scans.
Invite your VAs
You scan, they review, using your shared notes, blocklists, corrections, and saved filters.
