I just took a look at soundcloud and was able to get the data within a minute, as it's a basic setup. They use a json structure (most websites do) [1], and the data is fetched with a simply GET request.

If the website requires authentication, you just need to clone those requests too, and then you'll get some sort of cookie/session id back which you attach to any future requests.

As a bonus: You can then throw the json into a code converter online too which will convert your structure to a Type as well (useful if you are using a static language).
