# Metering

> List meters and retrieve meter metadata or consumption data for a project in the alpha Cognite Data Fusion API.

The **Metering** API exposes **meters** for a project: identifiers you can list and query to retrieve **meter metadata** or **historical consumption** (time-series style data with averaged values when you pass a time window).

You can list all meters, retrieve a meter by ID, and optionally request datapoints for a range using the list and retrieve endpoints. Access requires appropriate project capabilities (see the API reference for required ACLs).

<Warning>
  Metering is published in the **alpha** API reference only. Behavior, fields, and availability may change without notice. See [Alpha API reference](/api-reference/concepts/20230101/alpha-api).
