API

Catalogue, images and reference prices for your application.

The cardmarket.pro API delivers games, sets and printings, card images, reference prices in EUR with trend and history, variants by language and finish, and the condition scale – as a REST interface with JSON. Built for apps, collection tools, shop systems and research. Access is granted on request and is free for non-commercial projects.

At a glance

  • REST and JSON, version v1
  • Authentication with a key in the request header
  • 60 requests per minute, 5,000 per day as standard
  • Prices in EUR as cent amounts with a reference date

What the API delivers

The same data that powers the marketplace and the app – with cardmarket.pro’s own IDs.

  • Catalogue

    Games, sets with code and release date, and printings with collector number and rarity.

  • Images

    Listing and detail image per printing as an absolute URL, where an image exists.

  • Reference prices

    Trend and lowest reference price in EUR per printing with a reference date, plus the history of the last 30 days.

  • Variants and conditions

    Variants by language and finish, and the seven-step condition scale from Mint to Poor.

Who the API is for

  • Apps

    Scanners, deck builders and companion apps that recognise or display cards.

  • Collection tools

    Inventory management and portfolio valuation with current reference prices.

  • Shop systems

    Product data, images and price orientation for your own shop or point of sale.

  • Research

    Analyses of price development, availability and set structure.

Technical details

The API is a lean REST interface. Every response is JSON, every amount an integer in cents, every timestamp ISO 8601.

Endpoints

  • GET/api/v1/games

    Visible games with slug, name and kind

  • GET/api/v1/sets?game={slug}&page=1&pageSize=50

    Sets of a game with code, name, release date and card count

  • GET/api/v1/cards?game={slug}&q={text}&set={setId}&number={collectorNumber}

    Card search by game, text, set or collector number

  • GET/api/v1/cards/{id}

    A single card with images, variants, prices, price history and the condition scale

  • GET/api/v1/conditions

    Condition scale with code and name

Lists are paginated (page, pageSize); meta reports total and generatedAt.

Authentication

Every request carries the key in the x-api-key header. Keys start with cmp_live_, are personal and can be revoked at any time. Use them server-side only – never in the browser and never inside shipped apps.

curl -H "x-api-key: cmp_live_0123456789abcdef0123456789abcdef" \
  "https://cardmarket.pro/api/v1/cards?game=pokemon&q=dragon&pageSize=5"

Limits

  • 60 requests per minute per key
  • 5,000 requests per day as standard, more on request
  • Status 429 with a Retry-After header when a limit is exceeded
  • Responses can be cached for five minutes (Cache-Control)

Response format

Successful responses return data and meta. Errors come as error with code and message, for example unauthorized (401) or rate_limited (429).

Go to the help centre
  • Are the prices offer prices?

    No. They are reference prices per printing – a trend value and the lowest reference price, each with a reference date. They do not distinguish by condition and are not offers.

  • Is there a price history?

    Yes, the last 30 days as daily values for every card, where available. Longer periods are currently not part of the API.

  • May I cache responses?

    Yes, for five minutes. A permanent mirror of the data or passing it on as a dataset is not permitted.

  • What does access cost?

    Nothing for non-commercial projects. For commercial use we agree partner terms based on volume and purpose; they are set out in the agreement before the key is issued.
