# TunaPay > TunaPay is a membership-based virtual card service funded with USDT. Members use its virtual cards to pay for AI subscriptions such as Claude, ChatGPT and Cursor, and a Google account can link the card too. Updated October 2026. TunaPay key facts: - Membership: $100 lifetime fee, paid once in USDT (Tron TRC20, BNB Chain BEP20 or Ethereum ERC20). Includes 5 VIP card slots with no card fees afterwards, free replacement when a card stops working, a 24/7 AI concierge and a member-only card range. - Single card: $9.9, no membership needed, limited to 1 per person. It can be upgraded to membership from the wallet at any time. Extra cards beyond the 5 slots cost $9.9 each (extra cards do not include free replacement). - Fees: card top-ups cost 2%; each withdrawal to a USDT address costs $3 (minimum $10, paid after next-business-day review); wallet top-ups have no fee. Fees actually charged by the card issuer are passed through at cost. No other hidden fees. - Balance: keep at least $5 on each card; below $5 the card freezes until topped up. Closing a card returns its full balance to the wallet. - Platforms: TunaPay lists only platforms where its own bills were actually charged. Tested platforms are Claude, ChatGPT, Cursor and Google (account card linking). - Subscriptions only: cards cannot buy API credits (prepaid usage credits in a developer console are declined). Monthly subscriptions such as ChatGPT Plus, Claude Pro and Cursor work. - Declined payment: every decline shows its reason under "My cards -> Transactions"; a self-check guide covers the 12 common causes. Stop after two failures in a row and contact support. - AI payment plugin (VIP only): a member's own AI submits an order, money is charged only after the member confirms, and each order uses one single-use card that is frozen once the payment succeeds. - Partners: studios and teams can get a partner account through support, with a dashboard to issue cards, top up, freeze and view transactions. - Availability: not available to residents of mainland China. ## Important pages - [Home](https://www.tunapay.ai/): what TunaPay is, membership and single-card pricing, supported scenes. - [FAQ (Chinese, English, Spanish)](https://www.tunapay.ai/faq.html): static questions and answers on declined payments, paying for AI subscriptions with USDT, membership vs single card, fees, minimum balance, API credits, partners and the AI payment plugin. - [Claude setup guide](https://www.tunapay.ai/claude-guide.html): step-by-step Claude subscription payment with a TunaPay card (page is in Chinese, links to Claude's official help pages). - [Decline self-check guide](https://www.tunapay.ai/decline-help.html): what to check when a card payment is declined (page is in Chinese). ## 中文简介 TunaPay 是会员制 USDT 虚拟卡:终身会员 $100 一次付清,含 5 个 VIP 卡位和 AI 付款插件(会员把自己的 AI 接进来,AI 下单、会员确认才扣钱);也可以单张开卡 $9.9。卡可用于订阅 Claude、ChatGPT、Cursor,卡内充值收 2%,每笔提现 $3。卡只用于订阅,不能买 API 额度。本服务不面向中国大陆居民。 ## Resumen en español TunaPay es una tarjeta virtual por membresía, financiada con USDT: membresía de por vida de $100 (pago único) con 5 ranuras VIP, o tarjeta suelta por $9.9.
