FAQ

Where can I use the key?
Any client that supports the OpenAI API: Cursor, Cline, Cherry Studio, or the Python/Node SDK… Just point the Base URL to https://zc.authemasaka.id.vn/v1 and select model zcode/glm-5.3-flash.
How is the quota counted?
Quota is measured in tokens — usage is recorded per key and visible live under Account. When a plan's quota runs out, the key pauses automatically — upgrade or buy more to continue.
What happens when a plan expires?
The key pauses when the plan expires. Buy the plan again to renew — the new quota stacks onto the same key, so you never have to change keys in your client.
Is billing automatic?
No. Payment is a bank transfer each period, fully under your control — no card on file, no recurring charges.
