I notice you're not really using curl for anything complicated, so it seems more fitting to use the standard Net::HTTP backend instead. Here is a GitHub repository someone put together with example usage:

The reason I recommend this is because you don't have to worry about whether or not a machine has curl, and you also don't have to worry about shell parameter escaping since you're dealing with a remote host.
