Built for Data-Driven Platforms
CardSight AI provides the data infrastructure that analytics platforms need to deliver value to their users. Every price comes from a real sale or listing on eBay, Fanatics Collect, COMC, and other public marketplaces, and every record carries its price, date, source, and listing URL, so your users can see exactly where a number came from. Completed auctions show what buyers paid; Buy It Now listings show what sellers are asking. CardSight AI returns both, keeps raw copies apart from each grading company and grade, and rolls them into daily, weekly, and monthly time series. We handle the collection, card matching, and delivery so you can focus on the analytics and insights that differentiate your platform.

Everything Your Platform Needs
Data accuracy and completeness make or break analytics platforms. CardSight AI's API delivers the foundation: a 16M+ trading card catalog with every parallel and variation, price data that keeps raw and graded copies apart, time series ready to chart, population reports in beta, and 99.5% accurate CardSight identification for user-uploaded images. Market data is live for baseball, football, basketball, hockey, MMA, soccer, Pokémon, Magic: The Gathering, One Piece, and Disney. The API returns real comps rather than one synthesized estimate, so your models decide how to weigh them.

What You Can Build
CardSight AI's data enables analytics that used to require your own scrapers and card-matching pipeline. Chart the spread between sold and asking prices, measure what a grade adds to a card's value, line your own player stats up against card prices, spot mispriced listings across marketplaces, and value portfolios from real sales with the collections API. The examples below show a fraction of what platforms are building with CardSight AI, from simple price alerts to models that give collectors and investors a genuine edge in the market.
Price Tracking & Alerts
Chart any card's bid, ask, and spread by day, week, or month. Poll active listings and fire your own alerts when a price moves or a target card lists.
Market Analysis
Compare raw copies against each grade, watch the gap between what sellers ask and what buyers pay, and search listing titles across marketplaces, including listings never matched to a catalog card.
Portfolio Management
Store purchase and sale prices with the collections API, price up to 100 cards per call, and report realized gains beside current value.
Investment Intelligence
Put PSA population counts (beta, baseball) beside price history so scarcity and price sit in the same model. Compare cards across eras, sets, and grades.
