About OnePiece Terminal
OnePiece Terminal (onepiece.app) is a market data terminal for the ONE PIECE CARD GAME: live prices for more than 6,400 cards, booster box expected value, graded card values, PSA population reports, and an AI-powered card scanner, all in one place and updated every day.
What the Terminal does
- The Bounty Board: every English set priced against MSRP, with daily history back to 2024.
- Box EV: expected value of ripping every English booster box, computed from live singles prices and published pull-rate estimates.
- Whale Watch: statistically abnormal price moves, flagged the day they happen.
- Graded values and PSA population reports on card pages, joined to raw prices so you can see scarcity and premium together.
- The card scanner: photograph any card and get its live price in your browser, no app install.
- The TCG Fantasy League: open virtual boxes with real odds and real market prices, free.
Who runs it
OnePiece Terminal is built and run by a single independent collector, as a fan project. It is not affiliated with, endorsed by, or sponsored by Eiichiro Oda, Shueisha, Toei Animation, Bandai, or the Bandai Namco group. The site sells nothing and holds no inventory; it is a reference tool for the community.

Where the data comes from
Prices mirror TCGplayer market data. Graded values combine PriceCharting, real eBay sales, and community submissions reviewed by hand. Population data comes from PSA's published reports. The full detail, including how box EV is computed and how often everything refreshes, is on the methodology page.
