Overview

This node interacts with the QuickNode API to retrieve the balance of a specified Ethereum address. It is useful for blockchain developers, analysts, or applications that need to monitor or display the Ether balance of an address in real-time. For example, it can be used in wallet applications to show users their current Ether holdings or in automated scripts to trigger actions based on balance thresholds.

Use Case Examples

1. Retrieve the Ether balance of a user's wallet address to display in a dashboard.
2. Check the balance of a contract address before executing a transaction to ensure sufficient funds.

Properties

Output

JSON

• resource - The resource type, here it is 'blockchain'.
• operation - The operation performed, here it is 'getBalance'.
• result - The raw balance result in Wei (hexadecimal string).
• timestamp - The ISO timestamp when the data was retrieved.
• balanceWei - The balance in Wei (smallest Ether unit) as a hexadecimal string.
• balanceEth - The balance converted to Ether (ETH) as a decimal number.

Dependencies

• QuickNode API endpoint URL credential

Troubleshooting

• Ensure the Ethereum address is correctly formatted (starting with '0x' and valid length).
• Check that the QuickNode API endpoint URL credential is correctly configured and active.
• If the node returns an error from the QuickNode API, verify the API key and endpoint permissions.
• Invalid JSON or malformed requests will cause errors; ensure input parameters are correct.
