Darkbloom uses a prepaid credit model: you add funds to your account before making inference requests, and costs are deducted per request. Credits are loaded through the web console at darkbloom.dev using a credit or debit card via Stripe. This page walks through how the process works.
How to add credits
Open billing
Navigate to the Billing section from the sidebar.
Enter an amount
Enter the amount you want to add. The minimum deposit is $0.50.
Complete Stripe checkout
You will be redirected to a Stripe-hosted checkout page. Enter your credit or debit card details and confirm the payment.
Credits are applied
Once Stripe confirms the payment, your balance is updated automatically. You can start making inference requests immediately.
Credits are non-refundable. Unused credits remain in your account and do not expire.
Payment details
- Payment method: Credit card or debit card via Stripe
- Minimum deposit: $0.50
- Currency: USD
- Processing: Credits are applied automatically after Stripe confirms payment. There is no manual review step.
Do not close the Stripe checkout tab before the payment completes. If you do and the payment goes through, your credits will still be applied — but it may take a few seconds for the webhook confirmation to arrive.
Checking your balance after deposit
Once your credits are applied, you can verify your balance from the console or via the API:
