Overview

This node interacts with the Infura blockchain API to retrieve the latest block number on the Ethereum network. It is useful for scenarios where you need to know the current block height, such as monitoring blockchain progress, triggering actions based on new blocks, or synchronizing data with the blockchain state.

Use Case Examples

1. Monitoring the latest Ethereum block number to trigger downstream workflows.
2. Fetching the current block number to display blockchain status in a dashboard.

Output

JSON

• blockNumber - The latest block number in decimal format.
• blockNumberHex - The latest block number in hexadecimal format.
• metadata
  • network - The Ethereum network used (e.g., mainnet, rinkeby).
  • operation - The operation performed, here 'getBlockNumber'.
  • timestamp - Timestamp when the data was retrieved.
  • infura_endpoint - The Infura API endpoint used for the request.
  • raw_response - The raw response data from the Infura API.

Dependencies

• Infura API credentials including network, project ID, and optionally project secret for authentication.

Troubleshooting

• Ensure that the Infura API credentials are correctly configured and valid.
• Check network connectivity to Infura endpoints.
• If the node throws an 'Unknown operation' error, verify that the operation parameter is set to 'getBlockNumber'.
• If the API response is empty or malformed, verify the Infura project ID and network settings.
