answers 402

Japanese receipt (領収書/レシート) → normalized JSON + qualified-invoice verification in one call. OCR: merchant, date & time, items, totals and the 8%/10% consumption-tax breakdown. The registration number (T+13 digits) is extracted and verified against the National Tax Agency registry, so an expense agent knows instantly whether the receipt supports input-tax credit (仕入税額控除). Send {"url"} or {"base64"}

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
