# /{chain}/balances/{party}/history

Returns a party's Canton Coin balance history, aggregated by day. Each amount is the balance at the end of the day in UTC.
            
If both <i>startTimestamp</i> and <i>endTimestamp</i> are omitted, the API applies a trailing 30-day window ending at the current time.
