Cardometer editorial team — who we are and how we work
Cardometer is a trading card price tracker published by WXQ Sp. z o.o., the company behind Klockometr, a LEGO price comparison site. Every day we collect prices for 0 cards from 19 games and write guides for collectors.
Who we are
Cardometer is built by a team that has run price comparison sites for years. We combine knowledge of the card market (Pokémon, Magic: The Gathering, One Piece, Lorcana, Yu-Gi-Oh! and more) with reliable daily price data.
Founder of Cardometer and Klockometr (WXQ Sp. z o.o.). Responsible for data sources, pricing methodology and oversight of all guides. Contact: via the contact form.
Where our data comes from
- Card prices — trend, lowest price and averages from Cardmarket, Europe’s largest card marketplace, collected daily (details: how we price).
- Card catalogue and images — TCGdex, Scryfall, Lorcast, OPTCG API, YGOPRODeck and other open databases, complemented by the Cardmarket catalogue.
- Shop prices — sealed products from Polish shops, checked daily, with price history.
How our articles are made
Our guides answer questions collectors actually ask search engines. Every article is built on data from our database — price tables are generated live and update automatically. Drafts are prepared with the help of AI tools, and facts from outside our database are checked against the sources listed under each article. We have published 19 guides so far; new ones appear on Mondays, Wednesdays and Fridays.
Editorial principles
- Independence — we are not affiliated with game publishers or Cardmarket. Shop offers are sorted by price only, never by commission.
- Affiliate links — some shop links are affiliate links; we label them and they don’t change your price.
- No investment advice — we write about data and risks, we never promise returns.
- Dates — every article shows its publication and last update date.
Corrections
