Jisho Japanese Dictionary API

healthy 4,906 Subscribers

Japanese-English dictionary data via the open Jisho.org API (no key). The search endpoint queries the dictionary for words and kanji compounds and accepts English, romaji, kana or kanji as input; each entry carries its Japanese writings (word + reading), English senses with parts of speech and usage tags, JLPT level and a common-word flag, with an optional filter for common words only. The word endpoint returns the single best — preferably common — match for a keyword, ideal for quick look-ups and language tools. Real dictionary data straight from Jisho, cached briefly for speed — no key. 3 endpoints. Ideal for language-learning apps, furigana and reading helpers, vocabulary tools and Japanese NLP enrichment.

Kanji API

The Japanese kanji writing system as an API — every Jōyō, Kyōiku and Jinmeiyō kanji with its on/kun readings, English meanings, JLPT level, school grade, stroke count and newspaper frequency. Look up a single kanji (e.g. 字 → grade 1, JLPT 4, readings ジ / あざ, meanings "character, letter"), find every kanji that shares a kana reading (e.g. かじ), list the vocabulary that uses a given kanji, or pull a whole standard set (Jōyō 2,136 · Kyōiku · grade-1…grade-6 · Jinmeiyō) with paging. Backed by the open KANJIDIC2 / JMdict datasets via kanjiapi.dev. Ideal for Japanese-learning and flashcard apps, SRS/Anki-style study tools, furigana and reading aids, language-education platforms and linguistics research.

Urban Dictionary API

Urban Dictionary as an API — the crowd-sourced dictionary of slang, internet terms, memes, abbreviations and pop-culture expressions. Where a formal dictionary stops, Urban Dictionary explains the words people actually use online and in conversation: youth slang, gaming and meme vocabulary, acronyms, regional expressions and the ever-changing language of the internet. This API wraps the official Urban Dictionary service into a clean JSON interface. /v1/define?term=yeet returns the community definitions for a slang term, each with a real usage example, the contributing author, the up- and down-vote counts and a computed net score, sorted best-first so the most upvoted meaning comes first (or pass defid to fetch one specific definition by its id). /v1/random returns a batch of random definitions — perfect for a slang word-of-the-day, discovery features or fun. /v1/autocomplete?term=ye returns term suggestions as the user types, each with a short preview, for building search-as-you-type experiences. Ideal for chat and social apps decoding slang, language-learning and culture tools, moderation context, trivia and entertainment bots, and word-of-the-day widgets. Definitions are user-submitted and, by the nature of the source, may contain strong or NSFW language. Data from Urban Dictionary. For formal definitions, pronunciation and etymology, pair this with a standard dictionary API.

Ideal for search indexing and relevance, NLP preprocessing and text mining, keyword extraction, tag generation and content tooling.
