Questions
The essentials
How fast will my key work?
Immediately after automatic delivery on FunPay — the key is already activated and ready to connect.
Can the balance expire?
No. The balance on a permanent key has no expiry and never burns out.
Will it work in my IDE?
Yes, if the app supports an OpenAI-compatible Custom Endpoint — which almost every modern tool does.
