DeepBrain AI's video platform, AI Studios, lets you create avatar and AI-generated videos from text. If you want to move past the free tier, you'll need to add a payment method at checkout. This guide explains how to prepare a Coinepay virtual card, walk through the AI Studios sign-up and upgrade flow, and troubleshoot the most common reasons a card is declined.
Coinepay issues virtual cards with an instant card number, expiry date and CVV that you can use for AI subscriptions, software, advertising and online shopping. Before you start, note that AI Studios does not publish an exhaustive list of accepted card networks or whether prepaid cards are accepted, so confirm details in the Coinepay app and keep your plan flexible.
What you need before you start
- A verified Coinepay account. You must register and complete identity verification (KYC) before using card services. If you haven't yet, create your account and finish verification first.
- A Coinepay virtual card with enough balance to cover the plan you want, plus any taxes or exchange charges that may apply at checkout. Create or view your card in the Coinepay dashboard or mobile app (iOS / Android).
- Your real billing details. Use the name and billing address tied to your Coinepay account, not invented information.
- A DeepBrain AI / AI Studios account (covered below).
Card issuance and fund services are provided by licensed partner financial institutions, and some services are not available in every jurisdiction. Services related to virtual assets are not available to residents of mainland China.
Step 1: Create or sign in to AI Studios
Go to the official AI Studios website (aistudios.com) and open the sign-up page. You can register with Google, Microsoft, or an email and password. AI Studios states that no credit card is required to start, so you can explore the Free plan before deciding to pay.
Use your real identity when you register. Readers should not attempt to bypass any regional restriction with false details or location tools.
Step 2: Choose your plan
AI Studios' current video plans are Free, Personal, Team and Enterprise. There is also a separate Interactive Avatar Plan with Free, Standard and Enterprise tiers.
At the time of writing (October 2026), the pricing page displayed these USD figures:
| Plan | Listed price |
|---|---|
| Free | $0/month |
| Personal | $24/month billed annually ($288/year); $29/month billed monthly |
| Team | $55 per seat/month billed annually ($660/seat/year); $69 per seat/month billed monthly |
| Enterprise | Custom / contact sales |
| Interactive Avatar – Standard | $99/month |
Prices, taxes and local-currency checkout totals vary by region and can change, so always confirm the current figure on the official AI Studios pricing page before you buy. Enterprise normally uses invoices, and credit-card or prepaid arrangements for Enterprise are only supported in some countries.
AI Studios moved new sign-ups to unlimited-video plans in place of older credit-based plans. If you hold a legacy credit-based subscription, switching away was described as irreversible, so read the plan change carefully before confirming.
Step 3: Open Billing and upgrade
Once signed in, open the top-right profile menu and choose Billing. Here you can see your current plan and renewal date. Select Upgrade Plan to continue. AI Studios processes self-service upgrades through Stripe, so you'll be taken to a Stripe payment page to review and confirm the purchase. If you upgrade mid-cycle, expect a prorated charge.
Step 4: Enter your Coinepay virtual card
On the Stripe payment page, enter your Coinepay virtual card details:
- Open the Coinepay app or dashboard and view the card number, expiry date and CVV for the card you want to use.
- Type the card number, expiry and CVV into the Stripe form exactly as shown.
- Enter the cardholder name and billing address that match your Coinepay account.
- Review the total, billing cycle and renewal date, then confirm.
After the payment succeeds, your plan and next renewal date update in the Billing section. Subscription add-ons such as generative credits charge your existing saved payment method, so keep that card funded if you add them. Generative-credit add-ons are non-refundable and do not roll over.
Troubleshooting: why a card gets declined
AI Studios does not publish specific card-decline messages, so the guidance below covers the usual causes at a Stripe checkout. Work through them in order.
Insufficient balance
The most common cause is not enough available balance for the full charge, including any tax or currency conversion. Check your balance in the Coinepay app and top up, then retry. Remember annual plans bill the full year at once (for example $288 for Personal), which is a larger charge than the monthly rate.
Billing address mismatch
Stripe checks the billing address and postal code against the card record. Make sure the address on the payment form matches the billing details registered to your Coinepay card. Correct any typo and submit again.
3-D Secure / verification step
Some charges trigger a 3-D Secure confirmation. Approve the prompt through your Coinepay app or the verification method tied to your account. Keep the app open and notifications on so you don't miss the request, then complete the purchase.
Merchant or region checks
Checkout availability and accepted payment options can vary by country, and some generative models may be unavailable in certain regions. If a payment is refused for a reason unrelated to balance or address, it may be a merchant-side region or card-type check. AI Studios does not publish which card networks or card types (debit, prepaid) its self-service checkout accepts, and Enterprise card/prepaid support varies by country. If you suspect a card-type or region restriction, contact Coinepay support to confirm your card meets the requirement before you buy.
Card details entered incorrectly
Double-check the card number, expiry and CVV. A single wrong digit will cause a decline. Re-copy them from the Coinepay app rather than typing from memory.
If the payment still fails after these steps, reach out through Coinepay support or our Telegram channel, available 24/7, and contact AI Studios support for any merchant-side error.
Managing, cancelling and refunds
To cancel, go to profile → Billing → Cancel Subscription. The help guide asks for a reason and at least 30 characters of feedback before it confirms. Paid access continues until the end of the current billing period. To downgrade, cancel your current plan and choose a lower one after the billing period ends.
Under the terms last updated April 16, 2026, an ordinary refund requires a request within 14 calendar days of purchase with no use of the service at all; used services and partial periods are not refundable under that rule. Exceptions may apply for a demonstrable company billing error, a material company-attributable malfunction, or mandatory local law—request a review through AI Studios support with your account email and proof of purchase, and allow 5–10 business days for an approved refund to reach the original payment method. Keep your Coinepay card active so any refund can be received.
Quick checklist

- Approve any 3-D Secure prompt in the Coinepay app.
