eth_uninstallFilter

Uninstalls a filter with given id on the Chiliz network. This removes the filter and stops monitoring for events.

Parameters

• filterId (string, required): The filter identifier returned from eth_newFilter, eth_newBlockFilter, or eth_newPendingTransactionFilter

Returns

Returns true if the filter was successfully uninstalled, false if the filter was not found.

Implementation Example

Examples

cURL

curl -X POST https://api-chiliz-mainnet-archive.n.dwellir.com/YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_uninstallFilter",
    "params": [
      "0x1"
    ],
    "id": 1
  }'

JavaScript

const response = await fetch('https://api-chiliz-mainnet-archive.n.dwellir.com/YOUR_API_KEY', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    method: 'eth_uninstallFilter',
    params: ['0x1'],
    id: 1
  })
});

const data = await response.json();
console.log('Filter uninstalled:', data.result);

Python

import requests
import json

url = 'https://api-chiliz-mainnet-archive.n.dwellir.com/YOUR_API_KEY'
headers = {'Content-Type': 'application/json'}
payload = {
    "jsonrpc": "2.0",
    "method": "eth_uninstallFilter",
    "params": ["0x1"],
    "id": 1
}

response = requests.post(url, headers=headers, data=json.dumps(payload))
data = response.json()
print('Filter uninstalled:', data['result'])

Response Example

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": true
}

Notes

• Always uninstall filters when you no longer need them to free up server resources
• Filters automatically expire after ~5 minutes of inactivity
• Returns false if the filter ID doesn't exist or was already uninstalled
• Good practice to uninstall filters in error handling and cleanup code
