no, it should be requests.post("https://api.wasteof.money/posts", headers = authJson, json = {"post": f"hello world"})
I really wouldn't recommend replit. If you need the bots to be run daily, I'd recommend that if you have a Linux machine like an rpi, you can make a cron job for it.
:(
if you want to email me, I can help you by running it on rpi, but there might be other options out there.
