Product details and app entry points for trading-card sellers and repackers.
Scan a card, then review the details
The seller app offers front-and-back card scanning and identification. Review the result and correct card details before saving or listing. Identification is a starting point, not a guarantee of authenticity, condition or value.
Prepare an eBay listing
The eBay path uses your connected seller account and seller settings, including shipping location and policies. Check card details, price and selling terms before publishing. The account connection and listing workflow take place in the separate Listing Tool app, not on this information page.
Export saved cards to Whatnot
The Whatnot path is a CSV export for use in Whatnot's import workflow. It is not automatic publishing to Whatnot. A CSV export does not synchronize, pause or remove an eBay listing; sellers are responsible for managing the same card across channels.
Open the seller app
The Listing Tool — Enter here button on hobbyx.app opens the separate browser app at hobbyx-mobile.replit.app. Account, scan usage, plan information and seller settings are displayed there. Check the seller app for current availability and plan details.
