Careful with Cloudflare's "free" AI tier if you use paid workers. I was never able to get an answer on why I was billed for their confusing neuron usage for stuff that should have been covered under their usage limits. Their customer support just ignored my ticket. Apparently it's a known issue that they don't give a shit based on discussions in their support Discord.
Not disagreeing because I don’t know anything about this particular situation, but I think if you look at any company’s support discord, you will find that they don’t give a shit because of the sample bias. People whose problems they solved. Don’t end up there.
You should put anything like this on a privacy.com card with a monthly limit.

yeah their billing system truly sucks. One month I was charged exorbitantly for Workers Container usage. There was absolutely zero way to monitor or track your usage until the invoice arrived.
Another non-obvious Cloudflare default, not billing but just as silent: if the "Browser Integrity Check" is enabled by default, your API behind Cloudflare will return a 403 error for requests with the `Python-urllib` User-Agent. However, you won't see this in your server logs (these events appear only under Cloudflare > Security > Events). From your perspective, it will look as though these clients simply aren't accessing the API. You can fix this by turning off "Browser Integrity Check" (under Security > Settings) or by creating a rule to exclude API paths from the check.
