CardSight AI adds One Piece card identification and market data for developers

CardSight AI has added support for the One Piece Card Game, giving developers card identification, a structured catalog and bid/ask market data through the same API used for other major trading card categories. The launch is live now and is aimed at apps, marketplaces and collectors building One Piece tools.

Why it matters: - One Piece is one of the fastest-growing trading card games, and developers can now build collection, pricing and marketplace tools without assembling their own card-ID and data stack. - The addition expands CardSight AI’s single API across another major hobby category, which can reduce integration work for platforms that support multiple games.

What happened: - CardSight AI announced support for the One Piece Card Game on July 13, 2026. - The release adds One Piece card identification, a trading card database and structured market data to the platform. - Developers can identify a single One Piece card, multiple cards in one photo or a full page at once. - The launch is live now and free to start. - New developers can make up to 750 API calls without a credit card.

The details: - CardSight AI says the One Piece release uses the same API that already supports U.S. sports cards, Pokémon and Magic: The Gathering. - The CardSight AI Catalog now includes structured records for every One Piece set and card. - Each card maps to a stable identifier for consistent matching and display. - The platform provides bid/ask market data rather than a single estimated price or comp. - CardSight AI says its One Piece identification is custom-trained for real-world photos, including cards shot at angles and in varied lighting. - The company says the system can scan one card or many at once, without boxed-in, one-at-a-time scanning. - CardSight AI’s platform is available through a REST API, native SDKs and MCP endpoints. - The company says it identifies more than 12 million cards at 99.5% accuracy across Baseball, Football, Basketball, Hockey, Pokémon, Magic: The Gathering and now One Piece. - CardSight AI is based in Maine and is part of the NVIDIA Inception program. - More information is available at the company’s website. - The company also lists LinkedIn, Instagram, X and GitHub.

Between the lines: - The launch positions CardSight AI as infrastructure for hobby apps rather than a consumer-facing scanner alone. - By combining identification, catalog and market data in one layer, CardSight AI is targeting teams that want to build their own product logic on top of structured card data. - The focus on One Piece signals demand from builders in a category that has become harder to track with generic image matching as set counts, alternate arts and rarities expand.

What's next: - Developers can start integrating One Piece immediately through the existing CardSight AI API. - Teams already using CardSight AI for other card categories can add One Piece without a separate integration. - CardSight AI says its platform also connects with AI development tools including Claude Code and Codex, which could shorten build time for new card apps.

The bottom line: - CardSight AI is betting that One Piece builders want the same infrastructure stack already used for sports, Pokémon and Magic, with identification, cataloging and live market data all in one place.
