# /{chain}/balances/{party}/series

Returns the Canton Coin balance at each bucket opening. The start is inclusive and the end is exclusive. The `state` field distinguishes available balances from periods with no party history or periods before the party's first activity. Bounds must align to UTC midnight for `day` or the first day of a UTC month for `month`. Requests are limited to 31 daily or 13 monthly buckets.
