How charges work
Balance deducted
We deduct USDT from your balance equal to the provider’s price for those tokens. No markup.
Top-up volume discounts
The more USDT you top up at once, the bigger the discount on that top-up:| Top-up amount | Discount |
|---|---|
| 1 USDT | none |
| 10 USDT | small discount |
| 50 USDT | bigger discount |
| 100+ USDT | maximum discount |
Exact tiers and percentages are shown on the Top up page in your dashboard and may be adjusted occasionally. The discount applies at top-up time — when tokens are charged, you pay the vendor rate.
Transparency
Unlike resellers that mark up tokens, RuAPI gives you:- Zero token markup — the per-1M-tokens price equals the provider’s.
- Every request logged — see input/output split and exact cost in your dashboard.
- Volume discount only at top-up — no complicated tiered subscriptions.
USDT settlement
We accept payment in USDT (Tether) through several blockchains: TRC20 (TRON), BEP20 (BSC), Polygon. See the Top-up Guide. Internal accounting uses USD at 1 USDT = 1 USD. Token deductions are also in USD — no conversion to local currencies.Per-key spend limits
When you create an API key, you can set a spend limit in USD — a cap on how much that single key can draw from your overall balance. Useful for:- Production / staging / test keys with different limits.
- Sharing a key with a contractor with a tight budget.
- Protecting against runaway scripts.
