Are Japanese and English printings linked?

Yes. Both regions resolve to the same cardId while keeping separate printings, set codes, release dates and price series.

Do you track alternate art and manga art variants?

Every parallel, alternate-art, manga-art and Special treatment is its own printing with its own rarity, artist and market price.

Do you carry both the English and Japanese releases?

Yes, and they matter more here than in most games, because the Japanese release runs several months ahead of the English one. A set that is current in Japan may be unreleased in English, so a naive query can show players cards they cannot buy. Filter by language, and use the release dates on the set object to gate what you display.

How do you handle the parallel and manga rare printings?

Each is its own record with its own rarity, artwork and price series, linked to the standard printing so you can offer them as variants of one card. This matters commercially: a manga rare can trade for a hundred times the base version, and folding them together would make both prices meaningless.

Is deck legality validation available?

The data needed for it is. Each card exposes its colours, cost, card type and the set it came from, and leaders carry their colour identity, so the standard rules — fifty cards, one leader, four copies maximum, colours must be a subset of the leader's — can be checked entirely client side without a round trip per card.

Which price sources cover One Piece?

TCGplayer for the English market and Cardmarket for Europe, with Japanese singles tracked separately because the two markets rarely move together. A card in heavy demand in Japan can be quiet in the West for months after release.

Overview

What the One Piece dataset covers

The One Piece Card Game is the fastest-growing TCG of the decade, overtaking Magic and Yu-Gi-Oh! in tracked volume within four years of launch. TCGGraph structures every Leader, Character, Event, Stage and DON!! card with colour, cost, power, counter value, life, attribute and trigger text, and links English and Japanese printings — including alternate-art, manga-art and Special-rare treatments — to a shared identity.

English and Japanese printings resolve to one shared identity, so a card found in either language returns the same record with both markets priced.

The European market for One Piece

Bandai's European rollout trailed Japan by more than a year and allocations were thin for the first several sets, so early European stock is scarcer than the print numbers suggest. Spreads against the American market on OP-01 and OP-02 alternate arts remain some of the widest we track.

Traded on Cardmarket in German, French, Italian, Spanish beyond English. How European pricing works.

Modelling

Working with One Piece data

The decisions that catch people out when they first integrate One Piece. Each of these is a bug we have watched somebody ship.

Leaders are a different kind of card
A Leader is not a character you play from hand — it sits face up from the start, carries life and its colours dictate what the other fifty cards in your deck may be. Deck validation therefore starts with the leader, not with the deck list. Filter cardType=LEADER to build a leader picker.
Parallel art shares the card number
The same number, say OP01-121, covers the standard print, the parallel alternate art and any manga rare. They differ in rarity and in price by an order of magnitude. Number alone is not unique — pair it with rarity, or use the card id.
Counter is not a universal field
Counter values exist on characters and events and are absent everywhere else. Reading counter as a number without a null check will bite you the first time you touch a Stage or a Leader.
Set prefixes carry meaning
OP is a main booster, ST a starter deck, EB an extra booster and P a promo. Starter decks reprint main-set cards with a different number, so the same card can appear under two codes. Group on the card's name and effect if you want one logical entry.

Common One Piece queries

Three requests that cover most of what applications in this game actually ask for.

Every leader in a colour pair

Deck builders start by choosing a leader, which then constrains everything else.

colors matches any of the listed values, so this returns mono-red and mono-green leaders too.

GET /v1/cards
  ?game=one-piece
  &cardType=Leader
  &colors=Red,Green
  &include=prices

Cheap blockers with a high counter

A common deckbuilding query: low cost, useful counter value, has the Blocker keyword.

Numeric filters use min/max prefixes throughout the API, on every game.

GET /v1/cards
  ?game=one-piece
  &maxCost=3
  &minCounter=2000
  &keyword=Blocker
  &sort=cost:asc

Alternate art only, sorted by value

Collection and singles tools usually want the chase printings separated out.

Comma-separated values are an OR within a single filter.

GET /v1/cards
  ?game=one-piece
  &rarity=Special Rare,Manga Rare
  &include=prices
  &sort=prices.market:desc

Glossary

One Piece terms, and the fields that hold them

What players call a thing on the left, what you query on the right.

Term	Field	Notes
Life	onePiece.life	Leaders only. The number of cards in the life area at the start of play.
Power	onePiece.power	Integer in thousands. Absent on Events and most Stages.
Counter	onePiece.counter	Value when discarded to boost a defender. Null where the card has none.
Attribute	onePiece.attribute	Slash, Strike, Ranged, Special, Wisdom. Referenced by many card effects.
Type	onePiece.subtypes[]	Crew and affiliation tags such as Straw Hat Crew. Most tribal effects key on these.
Cost	onePiece.cost	DON!! needed to play the card. Leaders have no cost.
