How to get client_id

First, make a request like this:

GET / HTTP/2
Host: soundcloud.com

In the HTML response, you should see several JavaScript assets, like this:

<script crossorigin src="https://a-v2.sndcdn.com/assets/2-b0e52b4d.js"></script>
<script crossorigin src="https://a-v2.sndcdn.com/assets/49-4b976e4f.js"></script>

If you download asset 2, you should see this in the response:

?client_id=fSSdm5yTnDka1g0Fz1CO5Yx6z0NbeHAj&

If you download asset 49, you should see this in the response:

client_id:"fSSdm5yTnDka1g0Fz1CO5Yx6z0NbeHAj"

From my testing, asset 2 was smaller. The client_id seems to last at least a year:
