REST APIs

All REST API endpoints are available through the rest-api module. Note that some endpoints require authentication using your Binance API credentials.

1import { DerivativesTradingUsdsFutures } from '@binance/derivatives-trading-usds-futures';
2
3const configurationRestAPI = {
4    apiKey: 'your-api-key',
5    apiSecret: 'your-api-secret',
6};
7const client = new DerivativesTradingUsdsFutures({ configurationRestAPI });
8
9client.restAPI
10    .exchangeInformation()
11    .then((res) => res.data())
12    .then((data) => console.log(data))
13    .catch((err) => console.error(err));

More examples can be found in the examples/rest-api folder.

Configuration Options

The REST API supports the following advanced configuration options:

• timeout: Timeout for requests in milliseconds (default: 1000 ms).
• proxy: Proxy configuration:
  • host: Proxy server hostname.
  • port: Proxy server port.
  • protocol: Proxy protocol (http or https).
  • auth: Proxy authentication credentials:
    • username: Proxy username.
    • password: Proxy password.
• keepAlive: Enable HTTP keep-alive (default: true).
• compression: Enable response compression (default: true).
• retries: Number of retry attempts for failed requests (default: 3).
• backoff: Delay in milliseconds between retries (default: 1000 ms).
• httpsAgent: Custom HTTPS agent for advanced TLS configuration.
• privateKey: RSA or ED25519 private key for authentication.
• privateKeyPassphrase: Passphrase for the private key, if encrypted.

Timeout

You can configure a timeout for requests in milliseconds. If the request exceeds the specified timeout, it will be aborted. See the Timeout example for detailed usage.

Proxy

The REST API supports HTTP/HTTPS proxy configurations. See the Proxy example for detailed usage.

Keep-Alive

Enable HTTP keep-alive for persistent connections. See the Keep-Alive example for detailed usage.

Compression

1import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
2
3const configurationWebsocketStreams = {
4    wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
5};
6const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
7
8client.websocketStreams
9    .connect()
10    .then((connection) => {
11        const stream = connection.allBookTickersStream();
12        stream.on('message', (data) => console.info(data));
13    })
14    .catch((err) => console.error(err));

More examples are available in the examples/websocket-streams folder.

Certificate Pinning

To enhance security, you can use certificate pinning with the agent option in the configuration. This ensures the client only communicates with servers using specific certificates. See the Certificate Pinning example for detailed usage.

Subscribe to User Data Streams

You can consume the user data stream, which sends account-level events such as account and order updates. First create a listen-key via REST or WebSocket API; then:

1import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
2
3const configurationWebsocketStreams = {
4    wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
5};
6const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
7
8client.websocketStreams
9    .connect()
10    .then((connection) => {
11        const stream = connection.userData('listenKey');
12        stream.on('message', (data) => {
13            switch (data.e) {
14                case 'ACCOUNT_CONFIG_UPDATE':
15                    console.log('account config update stream', data);
16                    break;
17                case 'ORDER_TRADE_UPDATE':
18                    console.log('order trade update stream', data);
19                    break;
20                // …handle other variants…
21                default:
22                    console.log('unknown stream', data);
23                    break;
24            }
25        });
26    })
27    .catch((err) => console.error(err));

Unsubscribing from Streams

You can unsubscribe from specific WebSocket streams using the unsubscribe method. This is useful for managing active subscriptions without closing the connection.

1import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL } from '@binance/derivatives-trading-usds-futures';
2
3const configurationWebsocketStreams = {
4    wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_PROD_URL,
5};
6const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });
7
8client.websocketStreams
9    .connect()
10    .then((connection) => {
11        const stream = connection.allBookTickersStream();
12        stream.on('message', (data) => console.info(data));
13
14        setTimeout(() => {
15            stream.unsubscribe();
16            console.log('Unsubscribed from allBookTickersStream stream');
17        }, 10000);
18    })
19    .catch((err) => console.error(err));

Testnet

Websocket Streams also support a testnet environment for development and testing. Update the wsURL in your configuration:

1import { DerivativesTradingUsdsFutures, DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_TESTNET_URL } from '@binance/derivatives-trading-usds-futures';
2
3const configurationWebsocketStreams = {
4    wsURL: DERIVATIVES_TRADING_USDS_FUTURES_WS_STREAMS_TESTNET_URL,
5};
6const client = new DerivativesTradingUsdsFutures({ configurationWebsocketStreams });

If wsURL is not provided, it defaults to wss://fstream.binance.com.

Automatic Connection Renewal

The WebSocket connection is automatically renewed for both WebSocket API and WebSocket Streams connections, before the 24 hours expiration of the API key. This ensures continuous connectivity.

Testing

To run the tests:

1npm install
2
3npm run test

The tests cover:

• REST API endpoints
• WebSocket API and Streams
• Error handling and edge cases
