FAQ
Questions buyers typically ask before buying.
How does billing work?
You top up a balance (from $5) and pay only for the tokens your API calls consume. No subscription, no monthly fee.
What is the minimum top-up?
The minimum is $5. You can choose a preset amount or enter a custom amount.
Where is the gateway hosted?
Requests are served through a US-hosted gateway with an OpenAI-compatible API, so most tools work with a simple base URL change.
What happens when my balance runs out?
Calls stop until you top up again — no surprise charges, no auto-billing.
