A while ago, I noticed some very small oscillations in my Cloudflare R2 bill (1-2 cents / month) and decided to ask about it out of curiosity. Support was tepid - understandable for my $1 / month account - and it wasn't until later that I realized the difference probably had to do with the number of days in the month.
Would this API have helped?
seems like you fit the profile of the dude who uncovered a major fraud just due to his habit of checking minor increases/expenses
Translated: Close, but still not hard cost cap at Cloudflare.
Goes well with every other cloud provider refusing to offer a hard cost cap.
Unless of course you're on their credits then miraculously they do support a hard cap with every service stopping the second you go one cent over.
Vercel does. They don't get enough credit for it.
Zeit is good. Glory to Zeit.
