getVersion

Learn getVersion use cases, code examples, request parameters, response structure, and tips.

The getVersion RPC method in CoinVera returns the software version of the Solana node responding to the request. This includes the solana-core version string and a feature-set identifier, making it a valuable tool for diagnostics, compatibility checks, and monitoring.

✅ Common Use Cases

• Node Version Verification Confirm the version of the CoinVera RPC node you’re communicating with—for feature support or SDK compatibility.

• Network Monitoring Periodically query node versions across the network (use getClusterNodes for broader insight).

• Troubleshooting and Debugging Determine if issues may be version-specific by identifying the exact software build of the node.

📦 Response Structure

{
  "solana-core": "1.17.9",
  "feature-set": 123456789
}

• solana-core: The version string of the Solana software running on the node.

• feature-set: An internal identifier corresponding to the set of features enabled in this version.

🧪 Example

Get Current Node Version

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getVersion"
}

Response:

{
  "jsonrpc": "2.0",
  "result": {
    "solana-core": "1.17.9",
    "feature-set": 123456789
  },
  "id": 1
}

Code Examples

Nodejs

const fetch = require('node-fetch');

async function getVersion(rpcUrl) {
  try {
    const response = await fetch(rpcUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        jsonrpc: '2.0',
        id: 1,
        method: 'getVersion'
      }),
    });

    const data = await response.json();
    
    // Print the exact full response
    console.log('Full RPC Response:');
    console.log(JSON.stringify(data, null, 2));
    
    return data;
  } catch (error) {
    console.error('Error getting health:', error.message);
    return null;
  }
}

// Example usage
const RPC_URL = 'https://rpc.coinvera.io/?x-api-key=your-coinvera-x-api-key';

getVersion(RPC_URL);

Python

import requests
import json

def get_version(rpc_url):
    try:
        response = requests.post(
            rpc_url,
            headers={
                'Content-Type': 'application/json',
            },
            json={
                'jsonrpc': '2.0',
                'id': 1,
                'method': 'getVersion'
            }
        )
        
        data = response.json()
        
        # Print the exact full response
        print('Full RPC Response:')
        print(json.dumps(data, indent=2))
        
        return data
        
    except Exception as error:
        print(f'Error getting health: {error}')
        return None

# Example usage
RPC_URL = 'https://rpc.coinvera.io/?x-api-key=your-coinvera-x-api-key'
get_version(RPC_URL)

Example Response

{
  "jsonrpc": "2.0",
  "result": {
    "feature-set": 3073396398,
    "solana-core": "2.2.16"
  },
  "id": 1
}

💡 Developer Tips

• Simple and Fast This is one of the quickest RPC calls—ideal for lightweight health checks or CLI tools.

• Version Is Node-Specific The version returned reflects the specific CoinVera RPC node you're querying. During network upgrades, other nodes may be running different versions.

• Use Feature Set for Compatibility While version strings are useful, the feature-set number can be important for programmatic checks or runtime gating of features.

The getVersion method is a simple yet effective way to verify Solana software versions and ensure you're interacting with a compatible and up-to-date CoinVera node.
