For Marketplaces

Give Your Users the Listing Experience
They Already Expect

Major marketplaces have proprietary AI that makes listing effortless. Now you can offer the same experience: identify the card, produce the listing photo, and suggest a price from real sales, all from one upload and integrated in under a week.

Your Users Are Struggling

Card identification is the single biggest friction point in marketplace listing flows. Sellers arrive with cards to list but get stuck trying to figure out exactly which parallel, variation, or printing they have. They search through databases, compare images, read forums—wasting minutes per card. Many give up entirely, abandoning listings mid-flow and taking their inventory to platforms with better tools. The sellers who do complete listings often guess wrong, leading to incorrect pricing, buyer disputes, and returns. This isn't just a user experience problem—it's directly costing you GMV as frustrated sellers choose competitors who make listing effortless through AI-powered card identification.

Without Easy Identification:

  • Users spend 5-15 minutes researching each card
  • They guess (wrong) on parallels and variations
  • They abandon listings when it gets frustrating
  • They list on competitors with better tools
  • Their photos are crooked, dark, and full of tabletop
  • They price from a guess instead of recent sales

The Numbers Don't Lie:

  • Up to 40% listing abandonment rate during card identification
  • 3-5 minutes average time to identify a single card
  • Up to 25% of listings have incorrect card information
  • Potentially $1000s lost on misidentified parallels

Your competitors with card recognition see up to 3x higher listing completion rates.

The CardSight AI Solution

CardSight, our trading card identification, transforms your listing flow from a frustrating research project into an instant, accurate experience. Sellers snap a photo, and your platform returns complete card details in under a second—player name, year, set, card number, parallel type, and variation. The same photo comes back from CardMagic as a clean listing image, and CardSight AI price data suggests what to ask. Our 99.5% accuracy across 16M+ trading cards means sellers can trust the identification without second-guessing, and your buyers receive accurate listings that match what they're purchasing. Integration takes under a week: add our API endpoint to your upload flow, and suddenly you're competing with major marketplaces on listing experience. The result is measurably higher listing completion rates, reduced buyer disputes, increased seller retention, and more GMV flowing through your platform.
