# Network

> Mirror node REST endpoints for querying Hedera network supply, transaction fee schedules, exchange rates, address book nodes, and staking information.

## Overview

The Network Object in the Hedera Mirror Node REST API allows developers to query network-related information, such as network supply, fees, exchange rates, and node details. These endpoints are essential for monitoring network status, estimating transaction costs, and retrieving staking information.

## Endpoints

The following endpoints are available for the Network object:

| Endpoint                           | Description                                                                                                                                                            |
| ---------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `GET /api/v1/network/supply`       | Retrieves the current total supply of HBAR.                                                                                                                            |

| `POST /api/v1/network/fees`        | Estimates node, network, and service fees for a protobuf-encoded transaction, including the [HIP-1313](https://hips.hedera.com/hip/hip-1313) `high_volume_multiplier`. |
| `GET /api/v1/network/exchangerate` | Retrieves exchange rates to estimate transaction costs.                                                                                                                |
| `GET /api/v1/network/nodes`        | Lists the network address book nodes.                                                                                                                                  |
| `GET /api/v1/network/stake`        | Fetches staking-related information.                                                                                                                                   |
