### Overview

This endpoint returns the total number of active and up hosts in your Datadog account.
Active means the host has reported in the past hour, and up means it has reported in the past two hours.

This endpoint requires the `hosts_read` permission.

OAuth apps require the `hosts_read` authorization [scope](https://dnd37xeb23o8n.cloudfront.net/stefon.simmons/docs-astro-web-10435/api/latest/scopes.md#hosts) to access this endpoint.
