At the time, all the ones I could find were like $1/page or more like a $30/month subscription.

$0.05/page was well worth a cURL call, especially when the docs had great examples that just needed me to swap out the file name for mine.

I am likewise amused and completely agree with the idea. Every fax app I have used is either clunky, overpriced, or both. I hadn’t heard of Phaxio until now and am look forward to cURLing my next fax. However, there is some dark part of me that wants to make a clunky bash script for it nonetheless in order to keep me from enjoying sending a fax.
