FAQ

Questions

How do I pay?

In crypto (USDT/USDC) through Heleket. No bank card or foreign account required — useful where OpenAI/Anthropic billing isn't available.

Which tools does it work with?

Anything OpenAI-compatible: the Mason IDE, Cline, Roo, Continue, Cursor, aider, or your own scripts.

What is the "budget"?

Each plan is a monthly usage budget. You see the remaining balance live in the Mason IDE and your dashboard.

Can I still use my own keys?

Yes — the Mason IDE also supports BYOK and fully local Ollama models, free of charge.

Do you store my code?

The gateway records only token usage for billing — not your prompts or code.
