Does Kraken have an API?

Yes, Kraken does have an API that offers access to public market data and private account information, including trading and funding options. However, an alternative to using Kraken's public API is to use Mesh, which has built integration with Kraken along with 300+ other digital assets. This allows developers to build products that provide access to various cryptocurrencies, all from within the Mesh platform.

About Kraken

Founded in 2011 by Jesse Powell, Kraken is a cryptocurrency exchange based in San Francisco, California. The platform allows users to buy, sell, and trade over 200 cryptocurrencies, with a mission to accelerate the adoption of cryptocurrency for financial freedom and inclusion. Kraken has grown to serve over 7 million clients and employs between 1,001 and 5,000 people. In addition to spot and futures trading, Kraken offers staking, advanced trading through Kraken Pro, and a mobile app for convenient access to the platform.

General usage

The Kraken offers several functionalities with their REST API:

  1. REST API: Kraken's REST API offers comprehensive functionalities including market data retrieval, account and trade management, funding operations, subaccount features, and staking capabilities, catering to a wide range of trading and investment needs.

  • Intermediate Tier: Max Num Orders 80, Max Ratecount 125, Decay -2.34/sec
  • Pro Tier: Max Num Orders 225, Max Ratecount 180, Decay -3.75/sec
  • Penalties for order placements/cancellations vary based on order lifetime

Authentication

This is how you authenticate your Kraken API:

  1. Generate an API key via the Kraken website, and note down the key and secret.
  2. Choose the appropriate permissions for your API key based on your needs.
  3. Include the API-Key and API-Sign headers in your REST requests.
  4. Create a nonce as an always increasing, unsigned 64-bit integer for each request made with a particular API key. A common method for generating a valid nonce is to use a UNIX timestamp in milliseconds.
  5. Create the API-Sign header by generating an HMAC-SHA512 of the URI path and SHA256(nonce + POST data), using the base64-decoded secret API key. Base64-encode the resulting signature and include it in the API-Sign header.

Errors

Here are the common errors for Kraken API:

  • EGeneral: Invalid arguments - Check if the request payload is malformed, incorrect, or ambiguous.
  • EService: Unavailable - Ensure that the matching engine or API is online and not in cancel_only or post_only mode.
  • EAPI: Invalid key - Verify that the API key is valid and correctly supplied in the request headers. Make sure the API key has the necessary permissions for the requested action.

Recent changes
