How this industry works
Every other page here answers “which tool”.

What exchange API terms actually let you do
Public crypto endpoints answer without a key. The terms behind them still restrict redistribution, benchmarks and model training, and name an unpriced licence.

Where the bitcoin price actually comes from
There is no single bitcoin price — only trade prints on individual venues and the methods that combine them. What those methods decide, and which to use when.
