eth_getFilterChanges - Poll filter for changes

Get new NeuroWeb filter results. Event log polling.

Polling method for a filter, which returns an array of events that have occurred since the last poll on the Neuroweb network.

Implementation Example

Bash
curl -X POST https://api-neuroweb.n.dwellir.com/YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_getFilterChanges",
    "params": ["0x16"],
    "id": 1
  }'

Notes

  • This method only returns changes that occurred since the last poll
  • Filters timeout if not accessed within a certain time period (typically 5 minutes)
  • The first call to eth_getFilterChanges returns all events since filter creation
  • Subsequent calls return only new events since the previous call
  • Use eth_getFilterLogs to retrieve all accumulated logs regardless of polling
