QuantConnect IDE vs QuantConnect API

Hello,

I am wondering if anyone can help explain to me the difference between coding on QuantConnect.com IDE vs using the QuantConnect API?

As I went to look for QuantConnect  tutorials at:

https://www.quantconnect.com/docs/home/home

However when you click tutorials link it began talking about the QuantConnect API tutorials only. Is QuantConnect API what I use when writing algorithms in the online IDE? The coding examples seem to be the same as how I code in the online IDE, but we are also given an API key in which I do not use online. 

Anyhting Helps,

Thanks!

Hi Ryland! I can understand where the confusion came in. People talk about "QC API" in a few different pretexts - 

1) The interface for interacting with LEAN (the algorithmic trading engine) - with all the methods mentioned in the documentation. 

2) The interface for applications and tools we create for communicating with the QuantConnect website. ("Website API").

The community generally should never need to use the QuantConnect Website API directly, however, we provide a plugin for Visual Studio, and the ability to download FX data, both of which use the Website-API and require an API Key. 

We do not have documentation or tutorials for using the website API. It's generally not intended for public consumption. 

Hope that clears things up!
