Billing & Deposits
Gonka Broker uses a prepaid billing model. You add funds to your account, and those funds are consumed as you use the API. This page explains how that works.
Top-ups and deposits
Section titled “Top-ups and deposits”When you top up your account (via the Deposits tab), Gonka Broker creates a deposit. A deposit is a record of your payment that also captures the token prices at the exact moment you paid.
This means:
- If you top up $50 today and token prices go up tomorrow, your $50 still buys the same number of tokens it did today
- Each top-up is a separate deposit with its own locked prices
- Your total balance is the sum of all your active deposits
How deposits are consumed
Section titled “How deposits are consumed”Deposits are consumed in FIFO order (first in, first out). When your API keys generate usage:
- The cost is calculated using the prices locked in your oldest active deposit
- That deposit’s remaining balance decreases
- When a deposit is fully consumed, usage moves to the next oldest deposit
Example:
Imagine you made two top-ups on different days:
| Deposit | Amount | Price per 1M tokens (Model A) |
|---|---|---|
| Deposit 1 (Jan 15) | $20 | $0.30 |
| Deposit 2 (Feb 1) | $30 | $0.40 |
Your usage first draws from Deposit 1 at $0.30/1M tokens. After Deposit 1 is fully consumed, usage continues from Deposit 2 at $0.40/1M tokens. Your total balance reflects the combined token capacity of both deposits, each at its own rate.
Viewing your balance
Section titled “Viewing your balance”The Deposits tab in your dashboard shows:
- Current balance — your total remaining funds in USD
- Token balances — how many tokens you have available per model, calculated from your deposits’ locked prices
- Deposit history — all your top-ups with amounts and dates
Payment methods
Section titled “Payment methods”Gonka Broker accepts payments through Stripe:
- Credit and debit cards (Visa, Mastercard, and others)
- Apple Pay and Google Pay
- Stablecoins (USDC)
- Additional methods depending on your region (Link, Amazon Pay, Klarna, and others)
