What you avoid building
- Card data scraping pipelines (Cardmarket, TCGPlayer, Scryfall, ygoprodeck, …)
- Multi-language Pokémon catalog with master-card linkage
- Sealed-product database
- Photo-quality scoring + fake-detection
- Variant normalisation (foil/etched/1st-edition/…)
Verification signals
Every listing photo runs through our DINOv2 + capture-quality pipeline. Returns quality_score, fake_risk and color_reliability for marketplace trust badges.
