Why carry a smaller game like Grand Archive?

Because almost nobody else does, and the developers building for it have had to scrape or hand-maintain their own data. It is one of the better-designed games of the last few years and the tooling around it is thin, which makes it exactly the sort of catalogue worth carrying. It reads through the same schema and the same key as Pokémon or Magic.

How does champion lineage work in the data?

Each champion carries a lineage identifier shared by every level of that character, plus its own level. To build the progression, filter on the lineage and sort by level. To validate a deck, check that every champion in the list belongs to a single lineage and that the levels form a legal chain.

Are Grand Archive prices available?

Yes, though from a thinner market than the larger games, so single sales move the number more. We surface the number of observations behind each price point precisely so you can decide how much to trust it, rather than presenting a figure drawn from two listings as though it were a settled market.

How often is the Grand Archive catalogue updated?

New sets are ingested on release and prices refresh daily. Because the release cadence is slower than the major games, the catalogue is stable for long stretches — which is a feature if you are caching aggressively, and worth knowing if you are wondering why the changelog is quiet.

Overview

What the Grand Archive dataset covers

Grand Archive combines anime art direction with a genuinely novel resource system built on memory and reserve costs. TCGGraph exposes both cost tracks, level, power, life, durability, speed, elemental affinity and class lineage so you can model champion progression lines directly from the API.

Sourced from Grand Archive official API and TCGplayer.

The European market for Grand Archive

A small European footprint means shallow order books and wide spreads. This is the game where checking the seller count before acting on a quote matters most — a trend price behind four listings moves on a single sale.

Modelling

Working with Grand Archive data

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

Champions level up mid-game
You start with a level 0 champion and play higher-level versions of the same character on top as the game progresses. Lineage therefore matters: a level 2 Silvie can only be played over an earlier Silvie. Deck validation has to follow the lineage chain, not just count copies.
Two resources, two costs
Memory cost and reserve cost are separate currencies paid from separate pools. A card that looks cheap on one axis can be expensive on the other, and a single-number curve simply does not describe this game.
Speed decides when you may act
Fast actions can be played in response; slow actions cannot. It is a binary field and it changes how a card plays far more than its cost does, which makes it a much more useful filter than most people expect.
Editions carry different numbers
The same card reprinted in a later set gets a new collector number and its own artwork and price. The card's identity persists across editions, so group on the card id when you mean the card and keep editions apart when you mean a specific copy.

Recipes

Common Grand Archive queries

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

A champion's full lineage

Deck builders need every level of one character, in order.

Sorting by level gives you the progression from the level 0 starter upward.

GET /v1/cards
  ?game=grand-archive
  &cardType=Champion
  &name=Silvie
  &sort=level:asc

Cheap fast actions for a reactive deck

Speed plus memory cost is the filter pair that actually matters here.

Filtering on speed is far more informative than filtering on cost alone.

GET /v1/cards
  ?game=grand-archive
  &speed=Fast
  &maxMemoryCost=2
  &elements=Water
  &sort=memoryCost:asc

Class-legal allies above a power threshold

Your champion's class constrains what the rest of the deck may contain.

Classes are an array, so cards legal in more than one class match either filter.

GET /v1/cards
  ?game=grand-archive
  &cardType=Ally
  &classes=Assassin
  &minPower=3
  &include=prices

Glossary

Grand Archive terms, and the fields that hold them
