The Visual Novel Database vs Yu-Gi-Oh! Card Database

The Visual Novel Database (VNDB) is a free resource for information about visual novels and eroge, available on the web and through an API. Its wiki lets people add and contribute information, including general details and practical coverage of releases, localisations and producers. Registered users can vote on visual novels and maintain lists of games they want to play or have finished. VNDB also aims to introduce visual novels to a broader audience across geographic and cultural differences. The Kana HTTPS API can query the database and manage user lists. Non-commercial API access costs nothing and is subject to limits: 200 requests per 5 minutes, one second of execution time per minute, and automatic abortion of requests exceeding three seconds. API availability is best-effort, with no guarantees about stability or applicability. It does not provide some site functions, including forums, database editing and account creation. Users can obtain API tokens from the Applications tab in My Profile, and a sandbox endpoint at beta.vndb.org/api/kana is available for testing and development. VNDB's first version went live in September 2007.

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.
