About the first part, I am working on something similar for myself. If you want an api to get SMS for free, without needing any 10dlc stuff, check out groupme, which supports SMS.
For now, I think it would be funny if you put plaintext that says "just bought the milliondollargpt.com and have no idea what to do with it...". Optionally as a hyperlink to your comment I am replying to.
Awesome feature!
