Binance Data Connector

Want Bitcoin, Ethereum, or altcoin charts with live prices and no API key? The Binance connector talks to Binance public endpoints — history over REST, updates over WebSocket.

Use the controls above to change symbol and timeframe. This is the same integration you will copy into your app.

Standalone demo

Full-page version with sample code: Binance live demo.

What you get

Feature	Details
No API key	Public Binance market data
History	Up to 1,000 candles per request
Live ticks	WebSocket stream, auto-reconnect
Pairs	100+ symbols (BTCUSDT, ETHUSDT, …)
Timeframes	1m through monthly

Perfect for crypto dashboards, DEX frontends, and prototypes.

Install

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

Minimal example

import { createChart } from "@efixdata/exeria-chart";
import { BinanceAdapter } from "@efixdata/connector-binance";

const connector = new BinanceAdapter();

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

chart.init();

await chart.loadData("BTCUSDT", {
  interval: "1d",
  limit: 1000,
});

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

Step by step

1 — Create the connector

const connector = new BinanceAdapter();

Uses Binance public URLs by default. Optional tuning below.

2 — Attach to the chart

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

The chart delegates loadData and subscribeToUpdates to the connector.

3 — Load history

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

Option	Meaning
interval	Candle size — "1m", "1h", "1d", "1w", "1M"
limit	How many recent bars (max 1,000)
from / to	Optional date range instead of “latest N”

4 — Go live

chart.subscribeToUpdates("BTCUSDT");
// or with a callback:
chart.subscribeToUpdates("BTCUSDT", (tick) => { /* update UI */ });

5 — Clean up

chart.unsubscribeFromUpdates();
await connector.disconnect();

Popular symbols

Symbol	Market
BTCUSDT	Bitcoin / USDT
ETHUSDT	Ethereum / USDT
BNBUSDT	BNB / USDT
SOLUSDT	Solana / USDT
XRPUSDT	XRP / USDT

Symbol format is always BASE + QUOTE with no separator (BTCUSDT, not BTC/USDT).

Switch cryptocurrency

async function switchSymbol(newSymbol: string) {
  chart.unsubscribeFromUpdates();

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

  chart.subscribeToUpdates(newSymbol);
}

Always unsubscribe before loading a new symbol on the same chart instance.

Custom configuration (optional)

Defaults work for most apps. For retries or alternate REST host:

const connector = new BinanceAdapter({
  baseUrl: "https://data-api.binance.vision",
  requestTimeout: 10000,
  maxRetries: 5,
  retryDelay: 2000,
});

Error handling

try {
  await chart.loadData("BTCUSDT", { interval: "1d", limit: 1000 });
} catch (error) {
  if (error instanceof Error && error.message.includes("404")) {
    console.error("Symbol not found on Binance");
  } else {
    console.error("Load failed:", error);
  }
}

Show a retry button or message in your UI — users on bad networks will thank you.

Limits to know

Topic	Limit
Candles per request	1,000 max
REST rate	~1,200 requests/minute (Binance policy)
Browser	Needs WebSocket support (all modern browsers)

For heavy traffic: cache history server-side or use Binance's data API mirror.
