I am wanting to evaluate a polygon (A GET request to the API attached and the subsequent coords) and determine when the polygon is drawn, whether a specific coordinate falls inside the polygon or not. Not necessarily sure what framework or tool to use to attack this problem.

I would look into ray-casting algorithms

Any good ones that you know of?
