Installation

To use this library, ensure your environment is running Node.js version 22.12.0 or later. If you're using nvm (Node Version Manager), you can set the correct version as follows:

nvm install 22.12.0
nvm use 22.12.0

Then install the library using npm:

npm install @binance/derivatives-trading-portfolio-margin-pro

Documentation

For detailed information, refer to the Binance API Documentation.

REST APIs

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

import { DerivativesTradingPortfolioMarginPro } from '@binance/derivatives-trading-portfolio-margin-pro';

const configurationRestAPI = {
    apiKey: 'your-api-key',
    apiSecret: 'your-api-secret',
};
const client = new DerivativesTradingPortfolioMarginPro({ configurationRestAPI });

client.restAPI
    .getPortfolioMarginProAccountInfo()
    .then((res) => res.data())
    .then((data) => console.log(data))
    .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

Enable or disable response compression. See the Compression example for detailed usage.

Retries

Configure the number of retry attempts and delay in milliseconds between retries for failed requests. See the Retries example for detailed usage.

HTTPS Agent

Customize the HTTPS agent for advanced TLS configurations. See the HTTPS Agent example for detailed usage.

Key Pair Based Authentication

The REST API supports key pair-based authentication for secure communication. You can use RSA or ED25519 keys for signing requests. See the Key Pair Based Authentication example for detailed usage.

Certificate Pinning

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

Error Handling

The REST API provides detailed error types to help you handle issues effectively:

• ConnectorClientError: General client error.
• RequiredError: Thrown when a required parameter is missing.
• UnauthorizedError: Indicates missing or invalid authentication credentials.
• ForbiddenError: Access to the requested resource is forbidden.
• TooManyRequestsError: Rate limit exceeded.
• RateLimitBanError: IP address banned for exceeding rate limits.
• ServerError: Internal server error.
• NetworkError: Issues with network connectivity.
• NotFoundError: Resource not found.
• BadRequestError: Invalid request.

See the Error Handling example for detailed usage.

Testnet

For testing purposes, /fapi/* endpoints can be used in the Futures Testnet. Update the basePath in your configuration:

import { DerivativesTradingPortfolioMarginPro, DERIVATIVES_TRADING_PORTFOLIO_MARGIN_REST_API_TESTNET_URL } from '@binance/derivatives-trading-portfolio-margin-pro';

const configurationRestAPI = {
    apiKey: 'your-api-key',
    apiSecret: 'your-api-secret',
    basePath: DERIVATIVES_TRADING_PORTFOLIO_MARGIN_REST_API_TESTNET_URL,
};
const client = new DerivativesTradingPortfolioMarginPro({ configurationRestAPI });

If basePath is not provided, it defaults to https://api.binance.com.

Testing

To run the tests:

npm install

npm run test

The tests cover:

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

Migration Guide

If you are upgrading to the new modularized structure, refer to the Migration Guide for detailed steps.
