Coinbase Data Connector

Building for Coinbase users with USD or USDC spot pairs? The Coinbase connector talks to the public Advanced Trade API — history over REST, live prices over WebSocket. No API key required.

Standalone demo

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

What you get

Feature	Details
No API key	Public Coinbase Advanced Trade market data
History	OHLCV via /market/products/{id}/candles (paginated, 350 per request)
Live ticks	WebSocket ticker_batch with heartbeats keep-alive
Pairs	BTC-USD, ETH-USDC, and other Coinbase product ids
Symbol helper	Accepts BTCUSD, BTC/USD, bare BTC → BTC-USD

Install

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

Minimal example

import { createChart } from "@efixdata/exeria-chart";
import { CoinbaseAdapter } from "@efixdata/connector-coinbase";

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

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

chart.init();

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

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

Step by step

1 — Create the connector

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

Uses Coinbase 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-USD", {
  interval: "1h",
  limit: 500,
});

4 — Subscribe to live updates

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

Call subscribeToUpdates after loadData succeeds.

Docs demo proxy

Coinbase REST does not allow browser cross-origin requests from localhost. The docs dev server exposes /api/coinbase/ohlcv and /api/coinbase/ticker through apiProxyPlugin.js so live demos work without CORS errors. In your own app, call CoinbaseAdapter from Node.js or route REST through your backend.

Configuration

const connector = new CoinbaseAdapter({
  baseUrl: "https://api.coinbase.com",
  wsUrl: "wss://advanced-trade-ws.coinbase.com",
  requestTimeout: 10000,
  maxRetries: 3,
  retryDelay: 1000,
  pageDelayMs: 300,
  pollingIntervalMs: 5000,
  useWebSocket: true,
});

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

Supported symbols

You pass	Coinbase product_id
BTC-USD	BTC-USD
BTCUSD	BTC-USD
BTC	BTC-USD
ETH-USDC	ETH-USDC

Supported timeframes

1m, 5m, 15m, 30m, 1h, 2h, 4h, 6h, 1d

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