Does Poloniex API have an API?

Does Poloniex API have an API?

Yes, Poloniex API does have an API that provides both HTTP and websocket APIs for interacting with the exchange, allowing read access to public market data and private read access to the user's account. As an alternative to using Poloniex API's public API, consider using the Mesh API, which has built integration with Poloniex API along with 300+ other digital asset exchanges and wallets.

About Poloniex API

Poloniex, founded by Tristan D'Agosta in 2014, is a cryptocurrency exchange based in Boston, Massachusetts. The platform offers secure trading and advanced tools for buying and selling over 100 cryptocurrencies, including Bitcoin, Litecoin, Namecoin, and Dogecoin. With a flat rate of 0.2% on all trading transactions and no deposit or withdrawal fees, Poloniex has grown to employ between 251-500 people and was acquired by Circle in 2018.

General usage

Key aspects of Poloniex API include:

  1. Public Endpoints API: Accesses general market data, including order book details and trading pairs. This is useful for users who need insights into market trends and analysis.
  2. Private Endpoints API: Requires user authentication. It’s designed for managing personal trading activities, order management, and accessing account-specific details, essential for active traders.
  3. WebSocket API: Offers real-time market data streaming. This is crucial for applications that require immediate market updates, such as high-frequency trading systems.
  4. Webhooks API: Used for setting up automated responses to certain triggers within the trading environment. This enables users to automate reactions to specific market events.

Rate Limits

The Poloniex API enforces a rate limit for its trading API:

  • 6 calls per second

This rate limit is set to ensure optimal performance and stability of the API services.

  5. Ensure that your requests follow the guidelines and requirements outlined in the accounts section of the Poloniex API documentation.
