Cardmarket

Overview

Search Cardmarket's public product catalogs and read daily price-guide values in EUR. Supported games are Magic: The Gathering, Yu-Gi-Oh! and Pokémon. Catalogs include singles and other products such as boosters, boxes and decks.

No Cardmarket account, API key or app registration is required. Stackgate imports the public downloads on a shared schedule; tool calls search the imported data.

This integration is not affiliated with or endorsed by Cardmarket.

Using with AI clients

Connect your client to the hosted Cardmarket integration or enable it through your private gateway. See AI client setup.

Choose a game, search by product name prefix, and select the exact Cardmarket product ID before requesting prices. Different printings can have the same name. Cardmarket IDs differ from TCGdex card IDs.

Search ignores letter case and supports filters for singles or other products, category ID and expansion ID. Follow the returned cursor with the same filters to read another page. If an import replaces the dataset, restart the search.

Prices are daily guide values, not live seller offers. Results include source generation dates and a stale-data indicator. Average, low, trend and rolling-average fields are returned when available. Magic and Yu-Gi-Oh! use foil fields; Pokémon uses holo fields. These labels are preserved from the source and are not interchangeable. Missing values are null; numeric zero is a real value.

The public files do not provide language or condition-specific prices, expansion names, card images or rules. Inventory, orders and other account actions are unavailable.

Troubleshooting

• Data not ready: the first import for that game has not finished. Check dataset status or try again later.
• Stale or degraded data: the last complete import remains available after a download failure. Check source generation dates before using a price. Prices older than 48 hours are marked stale by default.
• No product found: search by the beginning of its name and verify the game. An expansion ID is not an expansion name.
• Price unavailable: some catalog products or individual price metrics have no price-guide value. Do not treat this as zero.
• Cursor expired: restart the search after the dataset or filters change.

Data comes from Cardmarket's public catalog and price-guide downloads. Cardmarket updates price guides daily and catalogs when new releases are added. Stackgate checks for updates daily; source dates may differ from the last successful check.
