WebSockets

Connect to Tokra's WebSocket API for real-time blockchain data including new blocks, transactions, and contract events.

Real-time blockchain data via WebSocket connections. Subscribe to new blocks, pending transactions, or smart contract events.

Connect to WebSocket:

Subscription Types:

New Blocks - Receive each new block as it's mined
Pending Transactions - Stream pending txs from mempool
Logs - Subscribe to smart contract events

Example:

const ws = new WebSocket('wss://ws.tokra.io/v1/eth/mainnet?apikey=tk_live_abc123');

ws.onopen = () => {
  ws.send(JSON.stringify({
    method: 'eth_subscribe',
    params: ['newHeads']
  }));
};

ws.onmessage = (event) => {
  const block = JSON.parse(event.data);
  console.log('New block:', block.params.result.number);
};
