Reading Data

This page covers the core data sources used by Drift UI so external builders can mirror the same state.

Data API overview

The Data API provides historical and aggregate data via simple REST endpoints. No authentication required.

REST endpoints

Market stats

Returns aggregate stats for all markets , volume, open interest, funding rate, oracle price, and market status.

GET https://data.api.drift.trade/stats/markets

Response shape:

[
  {
    "marketIndex": 0,
    "symbol": "SOL-PERP",
    "marketType": "perp",
    "oraclePrice": 123.456,
    "volume24h": 50000000.0,
    "openInterest": 12000000.0,
    "fundingRate": 0.00012,
    "fundingRate24hAvg": 0.00010,

This is the best single endpoint for building a markets overview or dashboard.

Response shape:

[
  {
    "ts": 1700000000,
    "symbol": "SOL-PERP",
    "marketIndex": 0,
    "fundingRate": 0.00012,
    "oraclePrice": 123.45,
    "markPrice": 123.50
  }
]

Trades

Returns recent trades for a market.

GET https://data.api.drift.trade/trades?symbol=SOL-PERP&limit=100

Query parameters:

• symbol , Market symbol (required)
• limit , Max results (default varies, max typically 1000)
• pageIndex , For pagination

Response shape:

[
  {
    "ts": 1700000000,
    "marketIndex": 0,
    "marketType": "perp",
    "filler": "...",
    "taker": "...",
    "maker": "...",
    "takerOrderId": 123,
    "makerOrderId": 456,
    "baseAssetAmountFilled": 1000000000,
    "quoteAssetAmountFilled": 123450000,
    "takerFee": 50000,
    "makerFee": -25000,
    "action": "fill",
    "actionExplanation": "orderFilledWithMatch"
  }
]

Note: Amounts are in protocol precision (base: 1e9, quote: 1e6). Divide accordingly for human-readable values.

Fetching data in code

// Fetch market stats for a dashboard
const marketsRes = await fetch("https://data.api.drift.trade/stats/markets");
const markets = await marketsRes.json();
 
for (const m of markets) {
  console.log(`${m.symbol}: price=${m.oraclePrice} OI=${m.openInterest} funding=${m.fundingRate}`);
}
 
// Fetch recent trades for a market
const tradesRes = await fetch(
  "https://data.api.drift.trade/trades?symbol=SOL-PERP&limit=100"
);
const trades = await tradesRes.json();
console.log(`Got ${trades.length} trades`);
 
// Fetch funding rate history
const fundingRes = await fetch(
  "https://data.api.drift.trade/fundingRates?symbol=SOL-PERP"
);
const fundingRates = await fundingRes.json();
console.log(`Funding rate entries: ${fundingRates.length}`);

Live data via websockets

The Data API also supports websocket subscriptions for live candles and trades:

const ws = new WebSocket("wss://data.api.drift.trade/ws");
 
ws.onopen = () => {
  // Subscribe to 1-minute candles for SOL-PERP
  ws.send(JSON.stringify({
    type: "subscribe",
    symbol: "SOL-PERP",
    resolution: "1"  // 1-minute candles
  }));
};
 
ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log("Candle update:", data);
};
 
ws.onerror = (error) => {
  console.error("WebSocket error:", error);
};

DLOB + Swift for live order flow

For real-time orderbook and order flow, Drift uses separate services:

• DLOB server (https://dlob.drift.trade) , Orderbook snapshots and streaming. See Orderbook + DLOB websocket.
• Swift server (https://swift.drift.trade) , Signed message orders for fast execution.
