The Onyx wallet: pay only for what you use
Start free, with no monthly fee. Each month you get an included allowance; if you go over, a few cents come out of your top-up balance. You stay in control and move to a plan only when it pays off.
1. What is included free each month
2. What you pay if you go over
Only when you go over the free allowance does it come out of your balance, at these prices (set by the Onyx team and updated here live):
Example: top up $10 and it covers about 67 extra Onyx AI analyses.
3. How to top up your balance
Top up any amount by card or USDT. Card top-ups carry a service fee that drops the more you add; USDT is credited at face value (no fee).
| Card top-up | Service fee |
|---|---|
| $0 – $24 | 8% |
| $25 – $49 | 6% |
| $50 – $99 | 5% |
| $100 – $199 | 4% |
| $200+ | 3.5% |
| USDT (TRC-20 / ERC-20) | 0% |
Minimum card top-up fee: $0.60.
4. Auto-reload (so you never run out)
Save a card and, when your balance drops below a minimum you choose, Onyx tops up the amount you set automatically. That way pay-as-you-go features never cut off. Turn it on or off anytime from your account.
5. When does a plan make sense?
If one month you spend more on usage than a plan costs (the cheapest is Guardian Pro, $19/mo), subscribing pays off: you pay less and unlock everything in the plan. The app itself tells you when it's cheaper. You always decide.
