Things to Know

  • Each coupon code can only be redeemed once per account
  • Credits from coupons never expire
  • Some coupons may have usage restrictions (e.g., first-time top-up required) — check the terms in your coupon email

​
Volume Discounts

When you top up above certain thresholds via Stripe, you automatically receive bonus credits on that purchase — no coupon code needed.
Top-Up AmountBonus
100–100 – 499+5% bonus credits
500–500 – 1,999+10% bonus credits
$2,000++15% bonus credits
Example: Top up $500 → receive 550,000,000 credits instead of 500,000,000 (10% bonus). Bonuses are applied at checkout time. The creditsToReceive field in the checkout API response reflects the final amount including any bonus: 
curl -X POST https://api.acn.exchange/v1/billing/checkout \
  -d '{"amountUsdCents": 50000}'  # $500

{
  "checkoutUrl": "https://checkout.stripe.com/...",
  "creditsToReceive": "550000000"
}
Volume discounts are visible in the dashboard top-up card as you enter an amount.
Volume discounts apply to Stripe top-ups only, not on-chain USDC deposits. Tiers are subject to change.
