CardSight AI is a complete trading card identification and data platform for developers. One unified trading card API spans baseball, basketball, football, hockey, as well as Pokémon, Magic: The Gathering, and One Piece TCG — with visual card recognition, real card sales data and graded card pricing sourced from eBay, Fanatics Collect, COMC, and other public marketplaces, free PSA population reports at the card and set level, and catalog access through REST endpoints and MCP for AI assistants.

CardSight AI is part of the Founder Residency at Northeastern University's Roux Institute, the AWS Startups and NVIDIA Inception programs, and is supported by the Maine Technology Institute.
Break out of the box.
Whether you're building a new app or adding card scanning to an existing platform, most identification APIs read one card per image — line it up, shoot, wait a second or two, repeat. Accurately scanning a full nine-card page, one at a time, runs over a minute.
CardSight AI detects and identifies every card in a single photo, at any angle — all nine at once, in under a second. It's the difference between a scanner your users tolerate and one they actually want to use.
Identifying these nine cards
One photo, nine cards. CardSight AI identifies them all at once — a competitor scanning one card per image takes over a minute to get through the same page.
Why builders integrate CardSight AI for the long run
Multi-card detection that scales. Scan a whole binder page, a stack on a table, or a display case at a show in one shot. Your users' workflow doesn't fall apart the moment they have more than one card.
One platform you won't outgrow. Identification, a 13M+ card catalog, real market pricing, and collection management sit behind a single API — add features without bolting on new vendors or re-architecting.
Purpose-trained computer vision. Not image hashing or k-nearest-neighbor — a reference-matching approach that only gets slower as the catalog grows. Our AI is trained on trading cards and runs at a fixed cost at any scale, fast enough for real-time video.

Real Market Price Data — Not Estimates
Completed auction results and live marketplace listings — sourced from public marketplaces, organized into raw and graded sections, parallel-aware, and bulk-priced up to 100 cards per request.
Sourced from eBay, Fanatics Collect, COMC, and other public marketplaces.
Historical Sales & Asking Prices
Completed auction results show what buyers actually paid. Buy-It-Now listing prices show what sellers are asking. Both come straight from the marketplaces we ingest, organized into raw and graded sections.
Live Marketplace Listings
Active auctions and Buy-It-Now listings available right now across eBay, Fanatics Collect, COMC, and other public marketplaces — with direct links so your users can verify and act.
Graded & Raw Breakdown
Graded data is organized by grading company (PSA, BGS, SGC, CGC) and individual grade. Compare PSA 10 sales against BGS 9.5 sales — or against raw — without any post-processing on your end.

Build Your Dream Trading Card App in Days, Not Months
The landscape of app development has fundamentally changed. What once required a team of machine learning engineers, months of training data collection, and deep technical expertise can now be built by anyone with an idea and access to modern AI tools.
In 2024-2026, AI assistants like Claude, ChatGPT, Cursor, and GitHub Copilot have transformed how we build software. These tools can write code, integrate APIs, and create full applications from natural language descriptions. But there's a crucial missing piece: domain expertise.
That's where CardSight AI comes in. While AI assistants are brilliant at writing code, they don't inherently understand trading cards. CardSight provides the pre-trained infrastructure—99.5% accurate card recognition in under 300ms—so AI tools can focus on building your unique vision instead of solving the complex computer vision problem.
You bring the idea. AI handles the code. CardSight handles the card intelligence.
Whether you're a collector with zero coding experience using ChatGPT, a developer accelerating your workflow with Claude Code, or an enterprise team building with full control, the same powerful CardSight API enables your vision. What used to take 6 months and a specialized team now takes a week and a conversation with AI.
Describe Your Vision, AI Builds It
No coding experience? No problem. Modern AI assistants like Claude, ChatGPT, Cursor AI, and tools like Bolt.new and v0.dev can generate entire applications from conversational descriptions.
The game-changer for trading card apps is CardSight's MCP (Model Context Protocol) integration. When you ask Claude or ChatGPT to build a card app, it can directly access CardSight's trained card recognition API—no need for the AI to understand computer vision or machine learning. It simply uses our pre-built infrastructure.
For example, tell Claude: "Build me a Pokemon card price tracker that identifies cards from photos and shows recent eBay sales." Claude generates the app code and integrates CardSight's API for card identification—something that would have required months of ML training just a few years ago.
While you'll still need to deploy your app (or ask AI to help with that too), AI assistants handle all the technical complexity: database setup, API integration, user authentication, responsive design, and most importantly, connecting to CardSight's card recognition endpoints.
"Create a web app for basketball card collectors that:
- Lets users upload card photos
- Uses CardSight AI to identify the card
- Shows card details and recent market prices
- Saves cards to a personal collection
- Has a clean, modern interface
Use CardSight's REST API for card recognition."Best for: Complete beginners, collectors with app ideas, rapid prototyping, non-technical entrepreneurs
