Payment and balance management
Your Fluence account has a prepaid balance in USD. Fluence charges rent for your CPU and GPU resources from this balance, so top it up before you launch anything. For how rent is charged, see the billing sections of CPU Cloud and GPU Cloud.
You can spend the balance only on Fluence resources, and you cannot withdraw it. If you need a refund, write to support@fluence.ai.
Top-up methods
| Method | Provider | How you pay |
|---|---|---|
| Crypto | NOWPayments | Cryptocurrency. You choose the coin and the network on the NOWPayments payment page |
| Card | Stripe | Credit or debit card on the Stripe checkout page |
| Promo code | Fluence | A code you received from Fluence |
AI agents and scripts can also top up without the console. They pay with x402 in USDC on Base over HTTP.
In the Fluence Console, the minimum top-up is 10 USD, and your balance cannot exceed 5,000 USD after the top-up.
You enter the amount in USD. The payment page adds processing fees, if there are any, on top. Fluence credits your balance with the amount you entered.
Top up the balance
1. Open the top-up dialog
Open the Billing page, for example by clicking the balance in the page header. In the My balance card, click Top up. The Top up balance dialog opens with Crypto selected.
2. Choose a method and enter the amount
Select Crypto or Card, enter the amount in USD, and click Top up. The payment page opens in a new tab.
If the console cannot confirm that the payment session was created, check the status of your top-up before you start another payment.
3. Complete the payment
- For Crypto, choose the coin and the network on the NOWPayments page. Then send the exact amount shown to the address shown.
- For Card, enter your card details on the Stripe checkout page and confirm the payment.
4. Wait for the payment to be credited
While the payment is in progress, the My balance card shows Waiting for payment and two buttons:
- Complete reopens the payment page, for example if you closed the tab.
- Cancel cancels the top-up.
When the payment is confirmed, Fluence adds the amount to your balance, and the top-up gets the Completed status. A card payment is usually credited right after checkout. A crypto payment is credited when its transaction is confirmed on the network.
You can have only one pending top-up at a time. To start a new one, complete or cancel the current one. An unpaid card top-up expires after 1 hour, and an unpaid crypto top-up expires after 24 hours.
Don't pay for a top-up that was canceled or has expired. If a payment arrives after that, write to support@fluence.ai to have it credited.
Top-up history
The Top-up history table on the Billing page lists your top-ups with their amount, deposit method, and status:
| Status | Meaning |
|---|---|
Pending | Waiting for your payment |
Under review | The payment was received but needs a manual check by the Fluence team before it is credited |
Completed | The amount has been added to your balance |
Expired | The top-up was not paid in time |
Canceled | You canceled the top-up |
Failed | The payment did not go through |
Promo codes
To activate a promo code, open the Promo code card on the Billing page, or the Promo code tab in the top-up dialog. Enter the code and click Activate.
Promo credits can have an expiration date. Fluence spends them before your prepaid balance.
