This endpoint extracts invoice registration numbers (T + 13 digits, with check-d
This endpoint extracts invoice registration numbers (T + 13 digits, with check-digit validation), total, subtotal, consumption tax with 8%/10% breakdown, and issue/due dates (Reiwa era converted to ISO) from Japanese invoice or receipt text using deterministic rules. Input is plain text only (no images or PDF). Registration numbers are checked by check digit only, not against the National Tax Agency registry. Malformed amounts are skipped and listed in warnings.
