Coinepay | How to Pay for Google Cloud Vertex AI with a Virtual Card

To pay for Vertex AI, you set up a Google Cloud billing account rather than buy a standalone Vertex AI subscription. Google now presents Vertex AI as part of Gemini Enterprise Agent Platform. This guide covers the Google Cloud developer platform—not Gemini consumer subscriptions or Gemini API billing in Google AI Studio—and explains where to enter a Coinepay virtual card, what to check before adding it, and how to handle a decline.

Before you start: check the billing requirements

You need a Google account, access to a Google Cloud project, and permission to create or manage its billing account. You also need to register with Coinepay and complete identity verification before using card services. Once issued, your virtual card’s number, expiry date, and CVV are available through Coinepay; you can manage the card in its dashboard or mobile app.

Check card eligibility before relying on it. Google lists American Express, Mastercard, Visa, and Visa- or Mastercard-branded debit cards among its accepted methods, subject to country and account availability. It does not accept prepaid cards for self-serve Cloud Billing or debit cards that require in-session two-factor authentication for recurring payments. Do not assume a virtual card meets those requirements. Contact Coinepay support to confirm your card meets Google’s applicable requirements before you buy; Google makes the final decision about a payment method.

Use your real name, billing address, and country when setting up the Google payments profile. Google’s billing country determines the account’s assigned currency, and neither can later be changed on that billing account. Check that your country, the service, and the model or endpoint you intend to use are available to you. Google restricts some Cloud services by location, and model availability varies between regional and global endpoints. A global endpoint does not guarantee data residency or in-region processing. Coinepay services also vary by jurisdiction and are subject to sanctions screening.

Understand what you are paying for

There is no single monthly Vertex AI subscription price. A paid Google Cloud billing account generally charges for applicable usage by service and model, with generative-model options that include Standard, Priority, and Flex/Batch rates. The Google Cloud Free Tier applies monthly no-charge limits to specified products; it is not a blanket free allowance for every Vertex AI model.

Eligible new customers may qualify for the Google Cloud Free Trial, which offers US$300 of Welcome credit for 90 days. Trial sign-up still requires a valid payment method and identity and payment-method verification. An authorization hold is not a purchase charge. Some uses, including Gemini API usage in AI Studio and managed partner-model APIs, are excluded from the trial credit. Check Google Cloud’s official Free Trial terms before assuming a workload is covered.

For an illustration of how model-specific pricing works, at the time of writing (October 2026), Google listed a Standard global-endpoint rate for Gemini 3.1 Pro Preview of US$2 per million input tokens and US$12 per million output tokens for requests with up to 200,000 input tokens. Other models, modalities, request sizes, and processing options have different rates. Prices and local-currency amounts can change: check the official Gemini Enterprise Agent Platform generative AI pricing page and the charges shown for your billing account before running a workload.

Set up Google Cloud billing with your Coinepay card

Prepare your card. Complete Coinepay registration and identity verification, then find your issued virtual card details in the Coinepay dashboard or mobile app. Check its available balance and any applicable card settings in Coinepay before entering it at Google Cloud.
Sign in to Google Cloud console. Create or select the project you will use for Vertex AI. If you are an eligible new customer, follow Google Cloud’s Free Trial sign-up flow and provide a valid payment method when requested. Verification may include an authorization hold.
Create a billing account if needed. In the console, open Manage billing accounts → Create account. Select your actual billing country and a new or existing Google payments profile. Review the country carefully because it and the assigned currency cannot subsequently be changed on that account.
Enter the payment information. If Google offers card entry for your account, enter the Coinepay card number, expiry date, and CVV. Use the real billing details associated with your payment profile. Review Google’s terms and the information displayed, then select Submit and enable billing.
Check the project and payment method. Confirm that the intended project is linked to the correct billing account before using Vertex AI. For a self-serve Postpay account, you can review or change a method under Billing → Payment method, after selecting the billing account. Payment-profile changes may require the appropriate permissions.

Adding a card does not itself reserve a particular model or establish a fixed monthly Vertex AI allowance. Review the model’s pricing, location, and any applicable credits before sending requests. Keep track of usage and your available card balance as charges accrue.

If you need Provisioned Throughput

Provisioned Throughput is a separate, fixed-term capacity commitment measured in generative AI scale units (GSUs), not a required step for ordinary pay-as-you-go use. Google lists one-week, one-month, three-month, and one-year terms. To order it, open Provisioned Throughput → New order in Google Cloud console. Choose the model, region, GSU quantity, term, and any renewal setting; review the estimate and terms; enter CONFIRM; and submit. Billing begins when the order becomes active.

Consider that commitment carefully: an active order cannot be cancelled mid-term. A pending-review order can be cancelled, and auto-renewal can be turned off for eligible active orders. Weekly terms do not auto-renew. Check Google’s current terms and pricing before submitting, rather than treating a pay-as-you-go card setup as approval for a capacity commitment.

Why was the card declined?

Start with Google Cloud console’s Transactions page: it may show an issuer reason if one was supplied. Then check Billing → Payment method for a Fix action. A decline can have several causes, so use the message and your account details to narrow it down rather than repeatedly submitting unchanged information.

Insufficient available balance: Check the card’s available balance in Coinepay against the amount Google is attempting to authorize or charge. Account for ongoing usage, not just the amount of your first request. Add funds through the options shown in Coinepay or use another valid payment method if needed.
Billing details do not match: Recheck the card details and the real name and billing address on your Google payments profile. Correct mistakes rather than entering an invented address or changing your country to pass a check.
Recurring-payment or authentication restrictions: Google may display “Your card does not support automatic recurring payments”. Its documentation also identifies issuer refusal of recurring charges and debit cards requiring in-session two-factor authentication as possible problems. Complete any legitimate authentication requested, but do not attempt to bypass it. Ask Coinepay support whether your card meets Google’s recurring-payment requirements; if it does not, choose another eligible method.
Region or card-policy checks: Google’s accepted methods depend on country and account. For example, Discover is listed only in the US, JCB only in Japan and the US, Visa Electron only outside the US, and Elo credit cards only in Brazil. Confirm that your actual billing country, payments profile, and card are eligible. Neither a different address nor a different region setting is a valid workaround.

If Google shows “General decline of the card. No other information was provided by the issuing bank”, its console may not contain a more specific explanation. Contact Coinepay support with the attempted charge details, without sending your full card number or CVV in a support message. You can then use Payment method → Fix or add another valid method. For an account billed in India, note Google’s warning that banks may decline automatic recurring card charges above ₹15,000; check the payment options available to your account rather than assuming a retry will resolve it.

How to stop charges or ask about a refund

A billing administrator can close a pay-as-you-go billing account under Billing → Account management → Close billing account. Linked services stop, but usage accrued before closure remains billable. Invoiced accounts must be closed through Google sales or support. If you have unused paid funds in an eligible Postpay payments account, look for Billing → Payment overview → Request a refund. Unused promotional credits and accounts with an outstanding balance do not qualify through that process. Closing an account does not automatically make previously paid fees refundable.
