Why Keydex
A service that stays out of your way
Straight to work
The key activates automatically after payment — no waiting for a seller or writing to support.
Full control
Live statistics in your account: balance, requests, and servers in real time.
No surprises
An unlimited balance, clear plans, and honest per-token pricing — nothing ever burns out.
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.
