Coinbase vs Kraken.io: What are the differences?

What is Coinbase? Integrate bitcoin payments into your website or application. Coinbase provides a simple and powerful REST API to integrate bitcoin payments into your business or application. We allow all major operations in bitcoin through one API.

What is Kraken.io? Image optimization and compression API. Kraken supports JPEG, PNG and GIF files. You can optimize your images in two ways - by providing an URL of the image you want to optimize or by uploading an image file directly to Kraken API.

Coinbase can be classified as a tool in the "Bitcoin Services" category, while Kraken.io is grouped under "Image Processing and Management".

Some of the features offered by Coinbase are:

• Buying and selling bitcoin (exchanging it to your local currency)
• Sending and requesting bitcoin by email or bitcoin address
• Accepting bitcoin payments as a merchant

On the other hand, Kraken.io provides the following key features:
