Index Constituents

/timeseries/index-constituents

Definition

An index constituent is a member of an index. For multi-asset crypto indexes, a constituent is a cryptoasset.

Details

Certain indexes consist of multiple index constituents. Such indexes weight constituents by one or more factors to determine the composition of the index. For instance, market capitalization-weighted indexes weight index constituents by their adjusted free float market capitalization. For each index that utilizes this approach, the index constituent data contains the constituents and their weights.

Index constituents and weights are calculated once an hour, every hour, including on weekends and holidays. Single asset indexes only have a single constituent, so no data will be returned for this endpoint. There are also no constituents for our CMBI Mining Series indexes.

Example

A sample of the constituents for the CMBI10 from our /timeseries/index-constituents API endpoint is shown below.
