Data Freshness & Historical Coverage

For data freshness and historical coverage, see Data Coverage by Chain; this endpoint follows it except where noted below.

• Returns a current, point-in-time snapshot of aggregated holdings — there is no date-range parameter or historical look-back; balances and their 24-hour change reflect within the standard live latency.
