A Few Lines of Code Away
Search the entire catalog with a single API call. Filter by sport, year, set, manufacturer, or any combination. Results come back structured and ready to display.
# Node.js / TypeScript
import { CardSightAI } from 'cardsightai';
const client = new CardSightAI({ apiKey: 'your_api_key_here' });
// Search the catalog
const results = await client.catalog.search({
q: "Shohei Ohtani rookie",
segment: "baseball",
min_year: 2018,
max_year: 2020,
take: 10
});
// Each result includes full card metadata
console.log(`Found ${results.data.total_count} results`);
for (const card of results.data.results) {
console.log(`[${card.type}] ${card.name} (${card.year})`);
console.log(` Set: ${card.setName} — ${card.releaseName}`);
}Why Build on Our Catalog
Assembling trading card data is deceptively hard. There are thousands of sets, millions of parallels, constantly shifting product lines, and no universal standard for card metadata. We have spent years solving this problem so you do not have to.
Normalized & Consistent
Every card follows the same schema regardless of sport, manufacturer, or era. No special-casing vintage versus modern. No inconsistent naming conventions. Build your UI once and it works across the entire catalog.
Continuously Updated
When Topps drops a new Chrome release or Panini launches a new product line, the cards are in our catalog before most collectors have them in hand. Your app stays current without any work on your end.
Parallel-Level Depth
Most card databases stop at the base card. Ours goes deeper — every refractor, color variation, numbered parallel, and short print is its own record. This is the level of detail that serious collectors and platforms require.
Infrastructure-Grade Reliability
99.9% uptime SLA, sub-300ms response times, and global CDN distribution. This is not a side project with a CSV file — it is production infrastructure built for platforms that depend on card data being available every second of every day.
Explore Our Platform
The catalog is even more powerful when combined with identification and collection management. Build a complete trading card platform.
Card Identification
Snap a photo, get instant card identification. 99.5% accuracy across 8,250+ sets.
Slab Identification
Read the slab, not just the card. Grading company, grade, and qualifiers from any photo.
Streaming Video
