Which trading card games have open prices? We audited every game
Everyone agrees a card’s price should be easy to look up. Fewer people ask who actually publishes that price, and whether anyone is allowed to reuse it. So we audited every game we track. Across 29 games and 399,406 card listings, only 3 have a free, open API that publishes prices in a form anyone can reuse. For the other 26, the price picture comes from one marketplace’s dataset.
The three games with open prices of their own
A free, open API that anyone can read and reuse, catalog and prices together, no approval and no fee.
| Game | Open source | What it publishes |
|---|---|---|
| Magic: The Gathering | Scryfall | Catalog plus EUR and USD prices |
| Pokemon (English) | pokemontcg.io | Catalog plus prices |
| Yu-Gi-Oh | YGOPRODeck | Catalog plus prices |
These three are the model for what open pricing looks like: a community-run database gives away both the catalog and the price, freely and with attribution. It is the reason the big games are so easy to value anywhere, on any site, including this one.
Open for cards, not for prices
Several more games have an open database of cards, sets and images, a real public good, but the broad price data still comes from a marketplace.
| Open catalog source | Game |
|---|---|
| Lorcast | Lorcana |
| digimoncard.io | Digimon |
| SWU-DB | Star Wars Unlimited |
| The Fab Cube | Flesh and Blood |
| Api TCG | One Piece, Gundam, Union Arena and more |
Everyone else, and the number underneath
That leaves most of the hobby. The remaining games in our census are visible, and priced, largely through one marketplace’s public dataset. It is a genuine service, and we use it and credit it. But it means a newer or smaller game has a price mostly because a marketplace chose to list it, and if it were dropped, the price would go with it.
Look one layer down and even the open APIs are redistributing marketplace numbers: nearly every price in the hobby starts at one of two large marketplaces. That is not a scandal, it is just how a thin market forms a consensus. The problem is not that marketplaces set prices. It is when that one number becomes the only price, when reusing it costs a fee or needs sign-off, and when a game has to be admitted before it has a price at all.
Foilio’s answer is the same one this study is built on: use the open sources, credit every one, show more than one market at once, and publish our own research openly under a Creative Commons license. It is why our prices are open, why we compare US and EU side by side, and why a free, open alternative for checking prices should exist at all.
Method & sources
- Scope: the 29 games and 399,406 listings from our card census, 84% of which carry a market price.
- Classification: a game counts as having its own open price API only if a free, publicly documented API returns both its catalog and its prices (Scryfall, pokemontcg.io, YGOPRODeck). Open catalog sources that do not publish broad prices are listed separately. Every source named here is one Foilio integrates and credits in its footer.
- No prices are printed in this study, and no marketplace is named as a villain. Foilio's integrated, footer-credited data sources plus the how-many-trading-cards census (Scryfall, pokemontcg.io, YGOPRODeck and the open tcgcsv.com TCGplayer dataset), all open; measured 2026-07-07, and free to reproduce from the open sources.
FAQ
Do most trading card games have open price data?
No. Of the 29 games in our census, only 3, Magic, Pokemon (English) and Yu-Gi-Oh, have a free, open API that publishes prices in a reusable form (Scryfall, pokemontcg.io and YGOPRODeck). For the other 26, roughly 90% of the games we price, the broad price picture comes from one marketplace's public dataset rather than an open, game-specific price feed of their own.
Where do trading card prices actually come from?
Almost every price traces back to one of the two large marketplaces where cards trade. The open question is whether you can freely read and reuse that number. For a few games an open API makes it free and attributed; for most, the reusable layer is thin and the price effectively lives inside one marketplace.
Which price and catalog sources are genuinely open and attributed?
Scryfall (Magic), pokemontcg.io (Pokemon) and YGOPRODeck (Yu-Gi-Oh) publish catalog and prices through a free, open API. Open catalog databases cover several more games (Lorcast for Lorcana, digimoncard.io for Digimon, SWU-DB for Star Wars Unlimited, The Fab Cube for Flesh and Blood, and Api TCG for several newer games), though their broad prices still come from a marketplace. Foilio credits every source in the footer of every page.
Why does open price data matter?
Because pricing decides what a buyer pays, what a collection is worth on paper, and even which games the market treats as real. When one marketplace's number becomes the only price, when reusing that number costs a fee or needs approval, and when a new game has to be listed by a marketplace before it has any price at all, collectors and smaller games are the ones who lose.
Is this audit against any marketplace?
No. Marketplaces are where trading actually happens, and their public prices are a genuine service that Foilio uses and credits. The point is pro-open, not anti-anyone: a price should be free to read and reuse, and every game deserves a source, not only the biggest three.
Can I reuse this data?
Yes. This audit, like every Foilio study, is free to cite under a Creative Commons license with a link. Foilio's integrated, footer-credited data sources plus the how-many-trading-cards census (Scryfall, pokemontcg.io, YGOPRODeck and the open tcgcsv.com TCGplayer dataset), all open; measured 2026-07-07.
