Gate.io Data Connector

Building for Gate.io spot markets? The Gate connector talks to the public API v4 — history over REST, live candles over WebSocket. No API key required.

Spot pairs

Timeframe

Loading chart…

Use the controls above to change currency pair and timeframe. This docs demo routes requests through /api/gate because Gate.io REST does not allow browser cross-origin requests.

Browser vs server

In your app, use GateAdapter directly from Node.js or your backend — no proxy required. The docs proxy exists only so live demos work without CORS errors.

Standalone demo

Full-page version with sample code: Gate.io live demo.

What you get

Feature	Details
No API key	Public Gate.io spot market data
History	OHLCV via /spot/candlesticks (paginated, 1000 per request)
Live ticks	WebSocket spot.candlesticks channel
Pairs	BTC_USDT, ETH_USDT, and other Gate currency pairs
Symbol helper	Accepts BTCUSDT, BTC-USDT, bare BTC → BTC_USDT
Timeframes	1m through 1d, plus 1w mapped to Gate 7d

Perfect for Gate-native trading UIs and browser-first crypto dashboards. For Node.js multi-exchange backends, see CCXT.

Gate.io vs CCXT

	Gate.io connector	CCXT
Runtime	Browser + Node	Node only
API key	No (public data)	No (public data)
Symbol format	BTC_USDT	exchangeId: "gate"
Live WS	Native Gate v4 candlesticks	REST-only in adapter-ccxt
Best for	Frontend Gate.io charts	Many exchanges on your server

Install

npm install @efixdata/exeria-chart @efixdata/connector-gate

Minimal example

import { createChart } from "@efixdata/exeria-chart";
import { GateAdapter } from "@efixdata/connector-gate";

const connector = new GateAdapter({ pageDelayMs: 300 });

const chart = createChart({
  container,
  dataAdapter: connector,
});

chart.init();

await chart.loadData("BTC_USDT", {
  interval: "1d",
  limit: 500,
});

chart.subscribeToUpdates("BTC_USDT", (tick) => {
  console.log("Last price:", tick.price ?? tick.c);
});

Step by step

1 — Create the connector

const connector = new GateAdapter({ pageDelayMs: 300 });

Uses Gate public URLs by default. Optional tuning below.

2 — Attach to the chart

const chart = createChart({ container, dataAdapter: connector });
chart.init();

3 — Load history

await chart.loadData("ETH_USDT", {
  interval: "1h",
  limit: 500,
});

4 — Subscribe to live updates

chart.subscribeToUpdates("ETH_USDT", (tick) => {
  console.log(tick.price ?? tick.c);
});

Call subscribeToUpdates after loadData succeeds.

Configuration

const connector = new GateAdapter({
  baseUrl: "https://api.gateio.ws/api/v4",
  wsUrl: "wss://api.gateio.ws/ws/v4/",
  requestTimeout: 10000,
  maxRetries: 3,
  retryDelay: 1000,
  pageDelayMs: 300,
  pollingIntervalMs: 5000,
  useWebSocket: true,
});

Set useWebSocket: false to poll REST /spot/tickers instead of WebSocket.

Docs demo proxy

Gate.io REST does not send Access-Control-Allow-Origin for browser origins, so direct fetch from localhost fails with Failed to fetch. The docs dev server exposes /api/gate/ohlcv and /api/gate/ticker through apiProxyPlugin.js. In production, run GateAdapter on your server or use WebSocket from a backend relay.

Supported symbols

You pass	Gate currency_pair
BTC_USDT	BTC_USDT
BTC-USDT	BTC_USDT
BTCUSDT	BTC_USDT
BTC	BTC_USDT

Supported timeframes

1m, 5m, 15m, 30m, 1h, 4h, 1d, 1w (mapped to Gate 7d)

Unsupported natively: 3m, 2h, 6h, 8h, 12h, 1M — the adapter throws a clear error.

Gate limits history to roughly 10,000 candles back per request window.
