# getInflationRate – Solana

{% hint style="success" %}
The **getInflationRate** RPC Solana method provides real-time inflation data for the current epoch, including the total inflation percentage, the amount allocated to validators, and the portion allocated to the foundation.
{% endhint %}

The getInflationRate method returns **the current inflation rate parameters** of the Solana network. It provides information on the expected annual inflation rate, staking rewards distribution, and total token supply adjustments, helping users and validators understand the network’s monetary policy.

### Supported Networks

This method is accessible through Solana API endpoints:

* Mainnet

### Parameters

{% hint style="info" %}
This method does not require any parameters.
{% endhint %}

### Request Example

#### API Endpoints

```json
https://go.getblock.io/<ACCESS-TOKEN>/
```

#### cURL Example

{% tabs %}
{% tab title="curl" %}

```json
curl --location "https://go.getblock.io/<ACCESS-TOKEN>/" -XPOST \
--header "Content-Type: application/json" \
--data '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getInflationRate"
}'
```

{% endtab %}
{% endtabs %}

### Response

A successful getInflationRate example response returns the **inflation rate breakdown** for the current epoch.

#### Example Response

```json
{
  "jsonrpc": "2.0",
  "result": {
    "epoch": 100,
    "foundation": 0.001,
    "total": 0.149,
    "validator": 0.148
  },
  "id": 1
}
```

#### In this response:

* `epoch` (`u64`): The epoch number for which the inflation rates are being reported.
* `foundation` (`f64`): The fraction of the total inflation allocated to the Solana Foundation. Typically expressed as a decimal (e.g., `0.001` = 0.1%).
* `total` (`f64`): The overall inflation rate for the network, expressed as a decimal (e.g., `0.149` = 14.9%).
* `validator` (`f64`): The fraction of the total inflation allocated to validators, also expressed as a decimal (e.g., `0.148` = 14.8%).

### Error Handling

Common getInflationRate error scenarios:

* Network connectivity issues: The request fails due to API unavailability.
* Node synchronization issues: If the node is out of sync, it may return outdated inflation values.
* Invalid response format: An unexpected JSON structure may indicate an internal API error.

#### Example Error Response

```json
{
  "jsonrpc": "2.0",
  "error": {
    "code": -32000,
    "message": "Inflation rate data unavailable"
  },
  "id": 1
}
```

### Use Cases

The Solana **getInflationRate** method is essential for:

* **Validators**: Monitoring expected staking rewards from inflation;
* **Blockchain explorers**: Displaying real-time inflation data for each epoch;
* **Web3 applications**: Adjusting economic models based on inflation distribution;
* **Analytics platforms**: Tracking inflation trends and network sustainability.

### Code Example – Web3 getInflationRate Integration

{% tabs %}
{% tab title="JavaScript" %}

```javascript
const axios = require('axios');

const url = "https://go.getblock.io/<ACCESS-TOKEN>/"; 
const headers = { "Content-Type": "application/json" };

const payload = {
  jsonrpc: "2.0",
  id: 1,
  method: "getInflationRate"
};

const fetchInflationRate = async () => {
  try {
    const response = await axios.post(url, payload, { headers });

    if (response.status === 200 && response.data.result) {
      const rate = response.data.result;
      console.log(`Inflation Rate:`);
      console.log(`Total: ${rate.total}`);
      console.log(`Validator: ${rate.validator}`);
      console.log(`Foundation: ${rate.foundation}`);
      console.log(`Epoch: ${rate.epoch}`);
    } else {
      console.error("Unexpected response:", response.data);
    }
  } catch (error) {
    console.error("getInflationRate error:", error.response?.data || error.message);
  }
};

fetchInflationRate();

```

{% endtab %}
{% endtabs %}

### Integration with Web3

Integrate the **getInflationRate** API with Solana’s Core API to retrieve real-time inflation rate data dynamically. By leveraging JSON-RPC parameters and endpoints, developers can ensure accurate tracking of staking rewards, inflation changes, and the impact of network economics on the Solana ecosystem.
