# How to Get All Asset Categories and Market Cap Changes

> Use the Metadata Categories endpoint to retrieve a list of all asset categories with market cap and percentage changes over 24h and 7d.

The [**Metadata Categories**](https://docs.mobula.io/rest-api-reference/endpoint/metadata-categories) endpoint lets you retrieve a list of all asset categories available in Mobula metadata.

It returns each category’s market cap plus percentage changes over the last 24 hours and 7 days.

This is useful for building category dashboards and market overviews.
