# Aggregation

## Definition

The count of underlying assets aggregated to compute metrics for that aggregate asset in that interval.

| Name                    | MetricID    | Unit   | Interval       |
| ----------------------- | ----------- | ------ | -------------- |
| Aggregated Assets Count | AggAssetCnt | Assets | 1 day, 1 block |

## Details

* Coin Metrics computes metrics for aggregate assets (e.g. combined or composite assets) by aggregating data across a set of underlying constituent assets.
* `AggAssetCnt` reports how many underlying assets were included in that aggregation for a given interval.
* This metric is useful for auditing completeness — if the count drops unexpectedly, it may indicate that one or more underlying assets did not report data for that interval.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gitbook-docs.coinmetrics.io/network-data/network-data-overview/availability/aggregation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
