Which API Endpoints Are Available for Binance US?
Binance, one of the world's leading cryptocurrency exchanges by trading volume, offers a comprehensive array of APIs tailored to support all kinds of users from traders and developers to bots and bots running on automated algorithms. The Binance US version, designed to comply with United States regulatory requirements, also provides API endpoints that can be utilized for various purposes. In this article, we will explore the different types of API endpoints available through Binance US for both public and private APIs.
Public API Endpoints
Public API endpoints are accessible by all users without needing an account or authentication with Binance US. They allow users to fetch real-time data from the exchange such as order book, market depth, trades, kline/candlestick, ticker 24h, and symbol information. Here is a brief overview of the public API endpoints:
1. Market Data: This endpoint allows users to access various market data including the current orderbook for any pair traded on Binance US, trade history, recent trades, kline/candlestick charts, 24 hour data, and symbol information. For example, when accessing this API, you can get up-to-date prices, volumes, total turn over values of a market within specific time ranges.
2. Symbols: This endpoint provides an array of symbols for trading pairs available on Binance US. It returns details about the token including precision digits for price and amount, base asset and symbol, quote asset and symbol, and if it is frozen or not. This can be crucial information when choosing which tokens to trade with due to their unique characteristics.
3. Server Time: Binance US provides an endpoint that allows you to fetch the current server time. This is useful for ensuring your system's clock is synchronized accurately with Binance's servers, especially when dealing with timestamps in requests.
4. WebSocket API: For users seeking real-time data updates, a WebSocket connection can be established using this endpoint. The WebSocket API supports market depth subscriptions where the client specifies the symbols and levels of depth they require for their subscription.
Private API Endpoints
Private API endpoints are restricted to authenticated Binance US account holders and allow access to more advanced functions not available through public APIs. These include trading, deposit/withdrawal, order status, account balance inquiries, and token transfers. Here's a rundown of the most significant private API endpoints:
1. Account Information: This endpoint allows users to view their account information including deposit addresses, frozen assets, and available balance. It also provides an overview of open orders.
2. Wallet Balance: The Wallet Balance endpoint enables users to query their balances for all or a specific asset type across multiple markets in the account.
3. Order Placement: This API allows users to place new orders on Binance US. It supports both market order and limit order types, with different parameters depending on whether it's an order for a single symbol pair or multiple symbols simultaneously.
4. Cancel Order: With this endpoint, users can cancel existing orders placed through the exchange. The user must provide the original request ID of the order they wish to cancel.
5. Replace Existing Order: This feature allows traders to replace an existing order with a new one. It's particularly useful when liquidity conditions change significantly or when market conditions indicate a better execution price.
6. Account Position: The Account Position endpoint provides information about open positions, including the total number of tokens held, the current cost basis for these tokens, and the unrealized PNL/profit and loss.
7. Deposit Addresses: Users can request new deposit addresses from this API to receive coins or tokens directly into their account without waiting for an existing address to be used up.
8. Deposit/Withdrawal Confirmations: This endpoint verifies the withdrawal details of a user’s assets and allows users to check if their assets are ready to be withdrawn.
9. Server Time: Like in the public API, Binance US also provides a private API endpoint for fetching the server time, which is useful for ensuring synchronization with Binance's clock when setting up an automated trading system.
