How to get live Duel Crash data

Crash multiplier plus the full provably-fair seed set (server seed + drand beacon) so you can verify every round. This guide shows the exact calls, with this game's real response shape.

1. Get the latest Duel Crash round

The fastest way to read the current state is /rounds/latest. The {slug} for Duel Crash is duel-crash.

bash

# Latest settled Duel Crash round
curl -H "Authorization: Bearer YOUR_KEY" \
  "https://api.trackersino.com/v1-beta/games/duel-crash/rounds/latest"

javascript

const res = await fetch(
  'https://api.trackersino.com/v1-beta/games/duel-crash/rounds/latest',
  { headers: { Authorization: 'Bearer YOUR_KEY' } },
);
const round = await res.json();
console.log(round.multiplier, round.finalized_at);

python

import requests
r = requests.get(
    "https://api.trackersino.com/v1-beta/games/duel-crash/rounds/latest",
    headers={"Authorization": "Bearer YOUR_KEY"}, timeout=10,
)
r.raise_for_status()
round = r.json()
print(round["multiplier"], round["finalized_at"])

2. Real response

A real /rounds/latest response for Duel Crash, captured from the live API:

json

{
  "round_index": 973831,
  "round_id": "973831",
  "multiplier": "1.5998",
  "state": "finalized",
  "finalized_at": "2026-06-01T12:34:03Z",
  "raw": {
    "id": 973831,
    "source": "duel.com",
    "multiplier": 1.5997744,
    "started_at": "2026-06-01 12:34:03",
    "server_seed": "dcb7ecb8296fc302fe7e9ac72a05effc2e00d0c5c677ca6363446a6d38d2d660",
    "server_seed_hashed": "5da2dab5a7366578cc89f57d2b416578a05b3f3e43b59fb4d05dc8325d5cbb5c",
    "drand_round_id": 29171293,
    "drand_randomness": "8e60b3e694d1b8f1bfa9c2aed74aebaa6cf1489cf3bc4f02ba8f8bc75edc5c9a..."
  }
}

Every round also carries the common envelope: round_index, round_id, multiplier, state, finalized_at and observed_at.

3. Duel Crash fields explained

multiplier

The crash point as a decimal string.

raw.server_seed / server_seed_hashed

The revealed server seed and its pre-published hash — verify the reveal matches the commitment.

raw.drand_round_id / drand_randomness

The drand randomness beacon round used as the public entropy source.

raw.started_at

When the round started, upstream timestamp.

4. History & last 5 minutes

To poll for recent activity, hit /rounds with a relative window. Both calls below return Duel Crash rounds, newest first.

bash

# Last 5 minutes of Duel Crash
curl -H "Authorization: Bearer YOUR_KEY" \
  "https://api.trackersino.com/v1-beta/games/duel-crash/rounds?window=5m"

# Last 200 rounds, history
curl -H "Authorization: Bearer YOUR_KEY" \
  "https://api.trackersino.com/v1-beta/games/duel-crash/rounds?limit=200"

# Walk older history with the backward cursor
curl -H "Authorization: Bearer YOUR_KEY" \
  "https://api.trackersino.com/v1-beta/games/duel-crash/rounds?limit=1000&until=2026-06-01T00:00:00Z"

Windows accept 5m / 15m / 30m / 1h / 3h / 6h / 12h / 24h / 72h / 7d / 30d, or use since_minutes=N for an exact minute count.

5. One-shot overview

/summary bundles Duel Crash's latest round, rolling counts (5m / 15m / 1h / 24h), the 24h multiplier shape and the delay table in a single call.

bash

curl -H "Authorization: Bearer YOUR_KEY" \
  "https://api.trackersino.com/v1-beta/games/duel-crash/summary"
