I don't understand how anyone uses a paid API for a personal project. I looked hard into MS, Google and Amazon a few years ago for a project and couldn't find anywhere where you could hard block services to never ever go above the free tier.
Considering that I'll build a project and forget about it for years, putting in my credit card into a cloud service was a guaranteed gigantic bill sometime in the future when things went wrong. (Over your life, something is guaranteed to go wrong.)
Have you heard of virtual debit cards? You can't charge what's not there.
Also, at least AWS will in fact send you an email when you approach the end of free tour usage.
Having said all that, most devs can host the few hundred visits they might get over a month with a $200 home server and a free CloudFlare cache if they know what they're doing.
None of those specifically, but after you have a virtualization host your flock tends to grow pretty quickly. More that I'm hosting big multi-user things like nextcloud for a single user.
