The problem you are describing is one that many large companies spend huge resources on today, so guarantee you that it is not something you do in a couple of days. Even if you had the system up and running, you would still need to create a large database system managing 100 billion data points each day and integrate the stream of information with your customers APIs. $2m worth of developer time going into this project is very likely. Thinking you could do this in a couple of days is simply ignorant.
