{"openapi":"3.1.0","info":{"title":"Jisho Japanese Dictionary API","version":"1.0.0","description":"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.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/jisho-api","description":"oanor
