Cool, this is the most important information.

The PHP array can be converted easily into a Python dictionary:

postfields = {
    "api_username": "john at domain.com",
    "api_password": "password",
    "method": "getServersInfo",
    "server_pop": "1",
}

I don't know what the CURLOPT_RETURNTRANSFER option does, so I'm going
to ignore it.

Since there's nothing obvious about the format of POST data, I'm going
to assume that it's meant to be form encoded. Give this a try and see
if it works.

r = requests.post("https://voip.ms/api/v1/rest.php", data=postfields)

Many APIs use JSON rather than form encoding, in which case you'd say
"json=" instead of "data=", but that seems unlikely in this case.

Assuming you haven't omitted anything important, the translation to
requests should be fairly straight-forward.

You'd need to match the PHP examples to the way Requests does file
uploads, but it ought to work.
