Overview

This node interacts with blockchain networks via QuickNode RPC endpoints to retrieve the current block number. It is useful for scenarios where you need to know the latest block height on a blockchain, such as monitoring blockchain activity, synchronizing data, or triggering actions based on new blocks.

Use Case Examples

1. A developer wants to monitor the Ethereum blockchain and trigger an alert whenever a new block is mined.
2. A blockchain analytics tool needs to fetch the latest block number to update its data index.

Output

JSON

• resource - The resource type, here it is 'blockchain'.
• operation - The operation performed, here it is 'getBlockNumber'.
• result - The raw result from the QuickNode API call, representing the block number in hexadecimal.
• timestamp - The ISO timestamp when the data was retrieved.
• blockNumber - The current block number as an integer.
• blockNumberHex - The current block number in hexadecimal format.

Dependencies

• QuickNode API endpoint URL credential

Troubleshooting

• Ensure the QuickNode API credential is correctly configured with a valid endpoint URL.
• If the node throws an error related to the API response, check the network connection and the validity of the QuickNode endpoint.
• Errors may occur if the blockchain network is temporarily unreachable or if the API rate limit is exceeded.
