IGDB vs Yu-Gi-Oh! Card Database

IGDB is a video game information database for searching games, companies, and characters. Search results can be sorted by relevance, title, release date, or rating, and the database accepts community contributions. Developers can query game data and related entities through its API, choosing fields, filters, sorting, and other request options. Non-commercial API use is free under the Twitch Developer Service Agreement. Commercial use requires a partnership, and products integrating the API are expected to show visible user-facing attribution. Access requires a Twitch account with two-factor authentication, an application Client ID and Client Secret, and OAuth2 application credentials. The API allows 4 requests per second, up to 8 open requests at once, and at most 500 results per request. Documentation provides daily-updated CSV data dumps and lists wrappers for several languages. Direct browser requests are not supported because the API has no CORS headers; a backend proxy is recommended. IGDB's API is available for free for non-commercial use, while commercial use requires a partnership.

Yu-Gi-Oh! Card Database is an official Yu-Gi-Oh! Trading Card Game site for searching cards, decks, products and rules. Card pages provide detailed information from each card’s release date. Users can look up public Deck Recipes, including tournament championship and runner-up decks, or search for decks containing a chosen card. Product listings show the cards included in packs, boxes and other releases, with information available from release. Users can register, organize and publish Deck Recipes, including Speed Duel and DUEL LINKS decks; logged-in users can also keep Owned Cards and Wish Lists. The database includes detailed rules and the latest Forbidden & Limited List for official tournament restrictions. Its Trends ranking draws on newly created decks and decks used in tournaments. The service is free and lists web, Android and iOS availability. Konami’s Yu-Gi-Oh! NEURON companion app connects to the database for deck management and can identify up to 20 cards at once using a smartphone camera. Some areas may require registration, and Web Service use requires linking a Card Game ID and KONAMI ID.
