Our AI vision model is trained on millions of trading card images. Upload a photo and get an instant match with full pricing and market data.
Snap & Identify
Upload or photograph any trading card and our AI identifies it in under a second. Works with raw cards, graded slabs, and partial images.
Slab Detection
Automatically detects grading company (PSA, BGS, SGC, CGC), reads the grade, and extracts the cert number from slab images.
Visual Similarity Search
K-nearest neighbor search across our entire card database finds the closest visual match, even for cards with minimal text or obscured details.
Instant Data Enrichment
Once identified, the API returns full card data — current market price, price history, population report, set details, and comparable sales.
Built For
