# Market cap ranking

## What is this endpoint for?

This endpoint aggregates from the [Supply](/rest-api/monitoring-solutions/kaiko-market-explorer/supply-and-market-cap/supply.md) 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](/rest-api/monitoring-solutions/kaiko-market-explorer/supply-and-market-cap/supply.md).

Read our supply and market cap methodology [here](https://resources.kaiko.com/hubfs/Factsheets%2c%20Rulebooks%2c%20Methodologies%20\(Resources\)/Data%20Feeds/Supply%20&%20Market%20Cap%20Methodology.pdf).
