> Nscale AI services use a credit-based billing system. To access AI services, you’ll need to purchase credits, which are deducted as you consume resources. You can monitor your balance, usage, and transaction history in the Usage & Billing section.

## **Purchasing credits**

To use the Nscale services, you'll need to purchase credits. Here's how:

**Adding credits via the console**:

* Navigate to **Usage & Billing** section and click the **Credit** tab.

* Select or type in the amount you'd like to purchase.

* Follow the Stripe payment flow to securely complete your transaction and add funds to your account.

* Upon successful transaction, the credits will be added to your account balance.

**Minimum and maximum purchase limits**:

<Note>
  The platform supports credit purchases from \$5 up to a maximum of \$10,000 per transaction.
</Note>

**Credit expiry**:

Purchased credits expire **3 years** after the date of purchase. You can view the expiry date for each credit commit in the **Credit** tab under **Usage & Billing**. Startup credits have a separate expiry policy.
