## About Kraken APIs
The REST-based Kraken API provides endpoints that return real-time cryptocurrency market data, including assets available for deposit, withdrawal, and trading.
## What is Kraken?
Kraken, a cryptocurrency exchange based in the United States, was founded in 2011 and offers crypto to fiat trading. Its service is available to residents of 176 countries as well as 48 US states. In addition, the company lists 70 different cryptocurrencies for sale and provides pricing information to Bloomberg Terminal, which offers real-time market data for analysis.
## How does Kraken work?
Kraken offers seasoned investors an advanced trading platform with features not often seen in other cryptocurrency exchanges, particularly the ability to utilize margins in trades. The service earns money through transaction fees based on the rolling volume an investor trades over a 30-day period.
## Who can benefit from Kraken?
Seasoned investors benefit the most from Kraken's advanced tools, while new investors would be better off with a different platform.
The Kraken API offers publicly accessible endpoints providing key metrics like market data and exchange status. Private endpoints require users to authenticate their accounts—these return account data such as user information, trades, and funding options.
## Why is the Kraken API necessary?
Any cryptocurrency exchange like Kraken should offer APIs for users to access market data for analysis. Furthermore, allowing users to access account data through APIs enables developers to build third-party tools that make trading more convenient for end-users.
## What can you expect from a Kraken API?
Remote authentication is a crucial feature of any API that accesses sensitive account information, so this is one characteristic to look for in APIs like Kraken. Also, the refresh rate of the API is another vital piece in the volatile cryptocurrency market, where trades can earn or lose depending on the value of the coins exchanged at any given time.
For developers, Kraken APIs have to utilize multiple safeguards to protect against DDOS attacks, order manipulation, and other system threats. It is also essential to ensure that the system refresh rate and the number of API calls allowed are sufficient for the end product to be successful.
