Amazon.ca (real DataForSEO search volume, 50–25,000/mo) and eBay.ca (real active-listing counts) side by side. Raw numbers only — nothing here is a made-up "opportunity score."
SEED_KEYWORDS_CA in app.py. Edit that list to change which niches get scanned — nothing here auto-expands into "every category" because neither Amazon's nor eBay's API supports that without seed terms.
