Market cap ranking

This endpoint aggregates from the Supply endpoint to provide an aggregated view of supply and market capitalization of the top assets at a specified time.

Data can be aggregated between 5-minute and 30-day intervals; the aggregation considers each 5-minute interval from the raw supply data.
