How to stream Crash rounds in real time

Subscribe to /v1-beta/stream over WebSocket and you get every finalised round pushed within milliseconds of our scraper writing it. Works for stake-crash, roobet-crash, duel-crash, shuffle-crash and their Slide siblings.

1. WebSocket URL

wss://api.trackersino.com/v1-beta/stream — optionally filter by ?games=stake-crash,roobet-crash. Auth via the same Authorization header you use on REST.

bash

# minimal subscription
wscat -c "wss://api.trackersino.com/v1-beta/stream?games=stake-crash,roobet-crash" \
      -H "Authorization: Bearer YOUR_KEY"

2. Frame shape

Each frame is one JSON object. game_id identifies the source; the rest of the fields mirror the /rounds response exactly.

json

{
  "game_id": "stake-crash",
  "round_id": "c2caaf8a-34b3-42b0-8d44-c01cb879049d",
  "round_index": 956100250495943837,
  "multiplier": "3.1611",
  "state": "finalized",
  "finalized_at": "2026-05-28T15:05:15Z",
  "multiplier_source": "stake",
  "raw": { /* full upstream envelope */ }
}

3. Reconnect strategy

We send a heartbeat ping every 25s. If you miss two consecutive pings, drop the connection and reconnect. On reconnect, the last finalized_at you observed is the resume point — backfill the gap via GET /v1-beta/games/{slug}/rounds?since=<last>.

4. Working example

Python (websockets)

python

import asyncio, json, websockets

URI = 'wss://api.trackersino.com/v1-beta/stream?games=stake-crash'
HEAD = [('Authorization', 'Bearer YOUR_KEY')]

async def main():
    async for ws in websockets.connect(URI, extra_headers=HEAD, ping_interval=20):
        try:
            async for msg in ws:
                r = json.loads(msg)
                if float(r['multiplier']) > 10:
                    print(f"🚀 {r['game_id']} {r['multiplier']}x at {r['finalized_at']}")
        except websockets.ConnectionClosed:
            continue  # auto-reconnect via for-async

asyncio.run(main())

Node.js (ws)

javascript

import WebSocket from 'ws';

function connect() {
  const ws = new WebSocket(
    'wss://api.trackersino.com/v1-beta/stream?games=stake-crash',
    { headers: { Authorization: 'Bearer YOUR_KEY' } },
  );
  ws.on('message', (data) => {
    const r = JSON.parse(data);
    if (parseFloat(r.multiplier) > 10) {
      console.log(`🚀 ${r.game_id} ${r.multiplier}x at ${r.finalized_at}`);
    }
  });
  ws.on('close', () => setTimeout(connect, 1000));
  ws.on('error', () => ws.terminate());
}
connect();

5. Multi-game subscriptions

Pass a comma-separated games= list to receive only the games you care about. Empty / missing = every game on your tier.

Edge cases?

Reconnect logic varies by stack. Ping us on Telegram with the language you're using and we'll send a production-ready helper (auto-reconnect, exponential backoff, gap detection via /rounds backfill).
