Paying ChatGPT and Claude with a U-card

This page is for individuals and developers paying Claude and ChatGPT subscriptions and APIs with a U-card: the platforms' official payment rules first, then cards suited to small subscriptions.

Pain points paying ChatGPT and Claude with a U-card

AI subscriptions are small, but they raise three problems ads don't: subscriptions renew monthly and get downgraded if the balance is short; API usage usually runs on prepaid credits that stop service when they run out; and many people subscribe on both web and mobile apps, where payment rules differ. This page compiles Claude's official payment rules and explains what we could verify for ChatGPT.

Official payment rules

Claude (Anthropic), from Claude's official help center:

Subscriptions bought on the web only accept credit or debit cards.
For subscriptions through the iOS or Android app, payment options are determined by the Apple App Store or Google Play.
A saved card may be charged if your default card is declined, so remove cards you don't want used.
A failed payment method can downgrade the account to free.
API and playground usage is billed through prepaid credits; when they run out you can't call the API until you add more. Auto-reload buys credits when your balance falls below a threshold you set.
Credits expire one year after purchase, and all credit purchases are non-refundable.

ChatGPT (OpenAI): OpenAI's help center presented a human-verification challenge during our check, so we could not read its payment articles and this page quotes no OpenAI payment rules. Refer to the official guidance on help.openai.com.

Selection criteria

No extra fees on small transactions: subscriptions and card-verification charges are small; PokePay officially charges no micro-transaction fee and KripiCard a 0% authorization fee, while Tevau gives 5 free small authorizations (under 3 USD) per card per month, then 0.2 USD each.
Low issuance cost: a year of subscriptions may cost only one or two hundred dollars.
Easy balance management: small top-ups at any time, topped up before renewal.
Eligibility: confirm your residence and documents fall within the issuer's policy first.

Recommended cards

The four cards below have official data on small transactions and issuance cost; whether a specific AI service accepts a charge depends on the merchant and issuer.

PokePay: PokePay is operated by PokePay Technology Co., Ltd. Very low spending-side fees (0 monthly, 0% cross-border); check the top-up fee in the app before opening. Issuance 5 usd; total cost at non-usd merchants ≥0.5%; accepts passport. Best for passport holders using the card mainly for subscriptions and online shopping; not for ad teams that need official confirmation of ad-platform behaviour. Read the full review

KripiCard: KripiCard is a virtual-only card platform. Publishes the bulk issuing and limits ad teams care about; the price is a 4% + 1 USD top-up fee. Issuance 5 usd; total cost at non-usd merchants 4.6%. Best for ad teams that need many virtual cards to separate accounts; not for small individual users sensitive to top-up cost. Read the full review

Bybit Card: Bybit Card is issued by the Bybit exchange. Easiest option if you already use Bybit, but paying non-USD merchants with USDT costs roughly 2.9% all-in. Issuance 0 usd; total cost at non-usd merchants ≥2.8%. Best for individuals already trading on Bybit and living in a supported region; not for ad teams that need many cards for separate accounts.

Binance Card: Binance Card is the Binance exchange's Global Program card, and its official fee page shows an update date of 2026-09-21. Transparent fees and cheap when paying in USDC, but available countries are only confirmed at application. Issuance 0 usd; total cost at non-usd merchants ≥2.8%. Best for individuals in supported countries who already use Binance; not for anyone needing confirmed mainland China eligibility; multi-card ad teams. Read the full review

Practical tips

Manage web and app subscriptions separately: in-app subscriptions go through Apple or Google payment, not your U-card.
Keep only one card on your Claude web subscription and remove saved cards you don't want charged.
Set API auto-reload threshold and amount conservatively and keep only enough balance for one or two reloads; credits expire after a year and aren't refundable, so don't overbuy.
Note renewal dates and top up in advance to avoid downgrades.
If a verification prompt appears, see what is 3DS; for more on subscription cards see cards for AI subscriptions.

Risks

Some AI services have their own requirements on the card's issuing region and billing address; if a card fails, check the merchant's official guidance first. U-card balances are usually not covered by deposit insurance, so keep only one or two months of subscription fees on a subscription card.

FAQ

Can I pay for Claude with a U-card?

Claude's help center says web subscriptions only accept credit or debit cards; whether a given U-card charges successfully depends on the card.

How is the Claude API billed?

Through prepaid credits; when they run out you can't call the API, and auto-reload is available. Credits expire after a year and purchases are non-refundable.

What are ChatGPT's payment rules?

OpenAI's help center showed a human-verification challenge during our check, so we couldn't read it and quote no rules here; refer to help.openai.com.

How much should I keep on a subscription card?

Keep only one or two months of subscription fees and top up before each renewal.

A U-card is only for passing payments through: top up only what you will spend, and never keep a large balance on the card.
