Japan Furigana API

Endpoints (6 live)

• POST /name-readings — List the possible readings of a Japanese (JP) name — person, company, or place — each with a probability, since names like 山崎 (やまざき / やまさき) are ambiguous without context. Returns hiragana, katakana, and romaji per candidate. Use for CRM name-matching, furigana fields, and call-list preparation. (0.005 USDC on Base)
• POST /normalize — Normalize Japanese (JP) text to a canonical form: fullwidth↔halfwidth conversion, halfwidth-katakana folding, invisible-character removal, and whitespace cleanup — each transformation toggleable. Returns a per-change log. Use to deduplicate or match text where '東京' and 'ﾄｳｷｮｳ' must compare equal. (0.001 USDC on Base)
• POST /furigana — Convert kanji-mixed Japanese (JP) text to hiragana, katakana, or romaji (Hepburn/Nippon/Passport), with a per-token breakdown of surface form, reading, and part-of-speech. Backed by the kuromoji morphological analyzer. Use to generate ruby readings, build search indexes, or preprocess text for speech synthesis. (0.005 USDC on Solana)
• POST /classify — Classifies text or input into furigana-related labels. (0.005 USDC on Solana)
• POST /batch — Converts text to furigana in batch for Japanese reading support. (0.0016 USDC on Base)
• POST /convert — Single-shot script conversion of Japanese (JP) text between hiragana, katakana, and romaji (Hepburn/Nippon/Passport styles). Lighter than /furigana — for text that is already kana, with no morphological analysis. Use for quick kana↔romaji transliteration. (0.005 USDC on Base)
