Frequently asked questions
Everything about billing, models, security and referrals.
How does billing work?
We reserve an estimated cost before each request, then reconcile against the exact token usage the upstream reports. The difference is refunded or charged instantly — you only pay for what you use.
Is the balance shared across my keys?
Yes. Your account has one balance. Every key you create draws from and settles against that same balance, so you top up once and use it everywhere.
Which models are supported?
All frontier Claude, GPT and Qwen models listed in the pricing table, addressable by their full name or a short alias.
How do I top up my balance?
Open the dashboard and create a crypto invoice from $5. Pay in LTC, USDT or any supported coin and your balance is credited automatically after confirmation.
How does the referral program work?
Share your referral link. Whenever someone you referred tops up their balance, you earn 10% of that top-up as credit — automatically, at payment time.
Is my API key stored securely?
Keys are stored only as SHA-256 hashes plus an AES-GCM encrypted copy. A leaked database dump reveals nothing usable, and you can protect your account with TOTP two-factor authentication.
