## When to prefer this

Use this endpoint when you specifically need Vietnam Northern (XSMB / Xo So Mien Bac) lottery results with the full multi-prize table structure. Prefer this over XSMT (Central) or XSMN (Southern) endpoints when the user asks about Hanoi or northern draws. Use it over the Vietlott endpoint when the user wants traditional number-table lottery rather than jackpot-style draws.
