Sample source code

Use the code provided below as a starting point for creating your own applications. We also have an open-source Kibot API Client application written in .NET that further demonstrates the communication between the client application and our servers. All data from our servers can be sent in a compressed format making the client-server communication and data download more efficient.

The source code below performs the following actions:

1. Logs in to the server using the Guest account
2. Downloads the last 10 days of daily data for MSFT (Microsoft)
3. Decompresses the Gzip data stream automatically
4. Saves decompressed data to a text file
