# Monitoring

> Monitor Air API requests, usage, and spending

AirCloud provides two levels of monitoring for Air API: **Project-level Monitoring** and **Organization-level Usage**.

<Note>
  Use **Project Monitoring** to analyze API requests and performance, and **Organization Usage** to track spending trends across projects over time.
</Note>

## Project Monitoring

From the Project sidebar, navigate to **Monitoring** and select the **Air API** tab to view API request metrics and spending for the current project over time.
