Understanding Endpoints

In the Kraken API, endpoints are categorized into two types: public and private. Public endpoints provide market data and exchange status, while private endpoints are used for trading, funding, and accessing user data. To leverage these endpoints, it is essential to understand their function and how to interact with them.

Public Endpoints: These are accessible to everyone and do not require authentication. They offer you historical and live market data for all of Kraken’s markets. Some examples include Ticker, Trades, and Order Book. Public endpoints are useful when you want to retrieve market data and incorporate it into your strategy or application.

Private Endpoints: These endpoints require authentication via API keys, granting access to trading functions, funding, and user-specific data. To correctly make an API request, you must sign the request headers using your API key and secret. Examples of private endpoints in Kraken API include AddOrder, CancelOrder, and QueryOrders.

When interacting with Kraken API endpoints, it’s essential to consider their status. The API status indicates the availability and performance of the endpoints. Monitoring the status helps you ensure seamless integration with Kraken’s platform and helps prevent unexpected errors or issues.

To make the most of Kraken API endpoints, consider the following tips:

  • Familiarize yourself with the input parameters and expected response format for each endpoint.
  • Always use the correct HTTP method (GET or POST) when making API requests.
  • Implement proper error handling for scenarios like exceeding rate limits or incorrect request parameters.
  • Continuously monitor the endpoint status to ensure the system’s responsiveness and stability.

Remember, the Kraken API is a powerful tool that allows you to interact programmatically with the cryptocurrency exchange platform. By understanding the public and private endpoints and their use cases, you can effectively enhance your trading strategies and integration with Kraken’s platform.

API Rate Limits

Kraken’s API rate limits are divided into three categories: public, private, and trading. These limits are implemented to protect the API against malicious usage and to maintain the integrity of market data.

In the public category, which includes market data, the rate limits are as follows:

  • Tier 1 and Tier 2 users have a limit of 1 call every 2 seconds.
  • Tier 3, Tier 4, and Payward Trading Token (PTT) users have a limit of 1 call every 1 second.

For private rate limits, related to account management, the tier-based limits are:

  • Tier 1: 5 calls per second (5/s)
  • Tier 2: 10 calls per second (10/s)
  • Tier 3: 15 calls per second (15/s)
  • Tier 4: 20 calls per second (20/s)
  • Payward Trading Token (PTT): 40 calls per second (40/s)

Lastly, the trading rate limits, which concern placing and canceling orders, are as follows:

  • LESS than 250,000 units of traded volume in the last 30 days, you’re limited to 1 new order every 8 seconds.
  • 250,000 to 2,500,000 units of traded volume, the limit is 1 new order every 6 seconds.
  • 2,500,000 to 25,000,000 units of traded volume, you can place 1 new order every 4 seconds.
  • Over 25,000,000 units of traded volume, the limit increases to 1 new order every 2 seconds.

Additionally, you can cancel up to 80 canceled orders every 200 seconds per instrument pair.

Remember that API rate limits protect both you and Kraken’s market data. Keeping these limits in mind will help ensure a smooth trading experience on the platform.

Understanding Assets and Markets

When using the Kraken API to access cryptocurrency data and perform trading operations, it’s essential to understand the concept of assets and markets. In this section, you’ll learn about assets, markets, and how they relate to each other.

Assets refer to the cryptocurrencies or fiat currencies available for trading on the Kraken platform. Common examples of assets are Bitcoin (represented as XBT), Ethereum (represented as ETH), and the US Dollar (represented as USD). Kraken API represents these assets with standardized codes like XXBT, XETH, and ZUSD respectively.

Markets (also known as trading pairs) represent the combinations of different assets that you can trade against each other on Kraken. A market has a base asset and a quote asset. For example, the XBTUSD market involves trading Bitcoin (XBT) against the US Dollar (USD). In Kraken API language, this market would be written as XXBTZUSD.

Here is a table that explains these representations:

AssetCodeKraken API Representation

Knowing the asset and market codes is crucial when making API requests. For instance, if you want to check the trading volume of XBTUSD market with a fee rate of 0.1%, you’ll need to use these codes in your request.

To obtain a list of all available assets and markets on Kraken, you can use the API Assets and AssetPairs endpoints. For example, calling the REST Assets endpoint ( returns a response containing all the assets, and calling the AssetPairs endpoint returns the available markets.

Remember to always refer to the official Kraken API documentation for the most up-to-date information about assets, markets, and their codes.
