Japanese Document Intelligence API

A document-AI API built specifically for Japanese business paperwork, where the global tools (ABBYY, Textract, Google) are weak. It reads invoices (validating the 適格請求書 T-number and 法人番号), business cards (meishi, with furigana), handwriting, hanko (印鑑) stamps, and faxes, and returns clean JSON: vendor, amounts, tax breakdown, dates, line items — with a confidence score. Multi-page PDFs and 元号 dates are handled.
