Billing & Usage

Overview#

The Billing page in your dashboard lets you view balance, purchase prepaid balance, and review transaction history.

Balance Overview#

Your dashboard displays your wallet balance:

• Bonus Balance — Granted from referrals and promotions, expires 30 days after being granted, spendable on Economy or Standard tier (never Premium)
• Prepaid Balance — Purchased balance that expires 12 months after purchase, spendable on Economy, Standard, or Premium tier

Every request is billed pay-as-you-go from your wallet — but the rate depends on both the tier and which wallet pays. On prepaid: Economy defaults to 0.2x, Standard defaults to 0.5x, Premium is always 1.0x. On bonus: Economy is 1.0x (no discount), Standard is 1.5x (a markup), and Premium isn't payable from bonus at all. A single Economy or Standard request can even draw from both wallets at once, at each wallet's own rate — see Provider Tiers for how that blended charge works.
