Pricing Overview
How FairStack pricing works. Transparent margins, no subscriptions.
FairStack charges a transparent 20% margin on top of provider costs. That is the entire business model.
How it works
- Each model has a published catalog rate -- per image, per second, per 1K characters, per track or per generation
- No subscription required -- pay per generation
- Your balance never expires
- See the exact cost before every generation with
confirm: false - No hidden fees, no overage charges
Adding funds
- No minimum balance. The minimum deposit is $1. Preset amounts: $1, $2, $5, $10, $25, $50, $100, $500, $1,000.
- Deposits under $10: the Stripe payment processing fee (about $0.30 + 2.9%) is passed through as a visible line item before you confirm. You pay the deposit plus that fee.
- Deposits of $10 or more: FairStack absorbs the Stripe processing fee -- 100% of what you add goes to your balance.
- Deposit bonuses: every deposit earns a standing bonus on the whole amount -- +2% at $25, +4% at $50, +6% at $100, and up to +10% at $500 and up.
- First top-up: we match it -- a 100% match, up to $5 added to your balance (one per payment method and email), with no deadline. A first top-up earns the larger of the standing bonus or the match, never both.
