I'm working on https://www.OnetimeFax.com - it's a way to send and receive faxes for a flat fee without needing to subscribe to anything.
Version 1 was a script I wrote for myself to fax the courts a jury duty deferral during covid lockdown, and then during my parental leave I productized it.
Wow, thanks for making it so easy for me to know who to call and what to say. They answered the phone in 1 second (seriously), I told them what I wanted to say, and they recorded my name and that was it.
At a previous job they refused to give me database access and instead insisted I ask them whenever I needed any columns added/altered, however I did have access to the code to do my job and...mysql root credentials were committed to the repo.
To keep the charade up I sent one of every 20 requests to them to do for me.
I watch some running race registration sites with Zapier and when it tells me that they are open I go register immediately so I can have a low bib number.
