How It Works
Full transparency on how AtomiScan analyzes the market and calculates profitability.
The Analysis Pipeline
Real-time market data ingestion
We track over 540,000 price points across TCGPlayer, eBay, and Cardmarket — every card, every condition, every grade. Data streams in continuously via licensed, official channels.
Cross-platform price comparison
Each card's price is compared across platforms and against rolling market averages (1-day, 7-day, 30-day) for that exact card, condition, and platform combination.
Significant price gaps identified
When a card's current price is significantly below its market average, it's flagged for profitability analysis. Normal fluctuations are filtered out.
Full fee calculation on both sides
We compute the real cost to buy AND the real return from selling, including platform fees, fixed fees, and shipping on both sides. See the fee table below.
Profitability filter
Only opportunities with positive net profit after all fees are surfaced. No theoretical numbers — real math with real costs.
Volume and liquidity check
Cards with fewer than 5 sales in 30 days are excluded. Low-volume cards carry resale risk, so we don't surface them.
Classified and delivered
Opportunities are ranked by ROI and delivered to your feed in real time. You decide whether to act.
Fee Breakdown by Platform
Buy Side (Shipping to You)
| Platform | Shipping |
|---|---|
| TCGPlayer | $1.50 |
| eBay | $2.00 |

Sell Side (Platform Fees + Shipping Out)
| Platform | Fee % | Fixed Fee | Shipping |

Profit Formula
buy_total = buy_price + buy_shipping
sell_fees = (sell_price × platform_fee%) + fixed_fee
sell_net = sell_price - sell_fees - sell_shipping
net_profit = sell_net - buy_total
ROI = (net_profit / buy_total) × 100%
Best Sell Platform Selection
For every opportunity, AtomiScan calculates net profit across all sell platforms and identifies the one with the highest return. The buy platform is fixed (where the opportunity was found), but we show you the optimal platform for resale.
About Affiliate Links
When you follow a link from AtomiScan to a marketplace, the link includes our affiliate tracking code. You pay the same price as everyone else — we earn a small commission from the platform (3.5% from TCGPlayer, 1-4% from eBay). This is how AtomiScan is free to use. We only earn when you find something worth buying.
