Codes de marché

For crypto, region is a market code that selects the source. The documented values are BA, BT and PB, with instrument codes such as BTCUSDT. See the iTick product list for which exchange each code maps to.

S'abonner via WebSocket

Crypto trades 24/7, and a WebSocket subscription keeps pushing updates so you do not need to poll. The example below subscribes to BTCUSDT quotes and ticks.

JavaScript
const ws = new WebSocket("wss://api.itick.dev/crypto?token=YOUR_API_KEY");

ws.onopen = () => {
  ws.send(JSON.stringify({ ac: "subscribe", params: "BTCUSDT$BA", types: "quote,tick" }));
  // Send a heartbeat at least every 30 seconds
  setInterval(() => ws.send(JSON.stringify({ ac: "ping", params: String(Date.now()) })), 25000);
};

ws.onmessage = (event) => console.log(event.data);

Questions fréquentes (FAQ)

How fast are the WebSocket updates?

Updates are produced by the upstream provider and forwarded to subscribed connections without caching. Actual latency depends on the upstream and the network, and we do not promise specific millisecond figures.

Which pairs and exchanges are supported?

That follows the iTick product list, and available instruments depend on your plan. See the iTick product list.

Does the free plan include WebSocket?

The free plan does not include WebSocket streaming by default; paid plans do. See pricing for connection and subscription limits.
