Whether you can pay for Claude with PAYCO depends on where the payment is made. claude.ai의 Pro·Max 웹 구독은 신용·직불카드만 받고, API를 직접 결제하는 Claude Console도 카드로 결제하며, Anthropic은 PayPal 같은 제3자 결제 처리업체를 받지 않는다고 안내합니다(Billing FAQ·Payment-method information, October 3, 2026 확인). iPhone 앱에서 구독하면 Apple이 결제를 처리하는데, Apple의 한국 결제 수단 목록에 PAYCO가 있습니다(Apple, 2026년 8월 6일 게시). Claude API와 클로드 코드(API 키 방식)는 Kunavo를 거치면 PAYCO로 충전할 수 있습니다. Stripe 결제 화면이 원화(₩)로 표시될 때 PAYCO가 선택지로 나오고, Prepaid from $10로 충전하며 잔액은 만료되지 않습니다. 다만 PAYCO 충전은 매번 직접 해야 합니다. Stripe가 PAYCO를 일회성 결제로만 지원해서 자동 충전에는 쓸 수 없습니다.
Can you pay for Claude with PAYCO?
Even when the payment is described as “paying for Claude,” the accepted methods differ depending on who receives the money. For comparison, ChatGPT and OpenAI API are included as well.
| Payment target | PAYCO | Evidence |
|---|---|---|
| claude.ai web subscription (Pro / Max) | Not available—credit and debit cards only | Anthropic billing FAQ (October 3, 2026 확인) |
| Claude Console (direct API payment) | Not available—cards; ACH bank transfer for some accounts only | Anthropic payment-method guidance (October 3, 2026 확인) |

| (Comparison) OpenAI API credits | Not available—dollar payments only | OpenAI Help (October 3, 2026 확인) |
The key point in the table is that PAYCO is not listed among ChatGPT web payment methods, but it is listed among Apple's Korean payment methods. Even domestic payment methods are accepted by different services, which is why the question “KakaoPay and Naver Pay work, but what about PAYCO?” arises separately. Kunavo in the final route is an independent gateway—not Anthropic or OpenAI—that provides their models through an API. A Kunavo balance topped up with PAYCO can be used only for Claude API, Claude Code run with an API key, and GPT API usage fees. It cannot pay for a claude.ai subscription, Anthropic Console credits, ChatGPT Plus, or OpenAI credits. The payment information is based on October 3, 2026. A table comparing every route, including KakaoPay and international cards, is available in Complete guide to paying for Claude; if your PAYCO account is ready, create a Kunavo account first and follow the steps below.
What PAYCO payment is—and what matters in this route
Stripe's PAYCO documentation divides PAYCO payments into two categories based on limits: payments made with a card linked to PAYCO, and payments made from a balance preloaded into the PAYCO account (stored value, called PAYCO Points in PAYCO). Stripe sets different limits for the two.
- When paying with a linked card: no maximum amount under Stripe. Stripe는 PAYCO에 연결한 카드로 결제하는 경우(card passthrough)에는 최대 금액이 없다고 안내합니다(Stripe PAYCO documentation, October 3, 2026 확인). 카드 자체의 한도는 그대로 적용됩니다.
- PAYCO Points: top up to a maximum of 2 million won. 같은 Stripe 문서는 PAYCO 계정에 충전해 둘 수 있는 잔액(stored value)을 최대 2 million won으로 적고 있습니다. PAYCO는 포인트를 1원에 1포인트로 충전해 현금처럼 쓰는 결제 수단이라고 소개하고, 계좌·무통장 입금·휴대폰 결제·컬처랜드·티머니·PAYCO 상품권·PayPal로 충전할 수 있다고 안내합니다(PAYCO Points information, October 3, 2026 확인).
- PAYCO Points’ ‘automatic top-up’ is different from Kunavo automatic top-up. PAYCO는 결제할 때 포인트가 모자라면 연결 계좌에서 1만 P 단위로 채우는 기능을 안내합니다(PAYCO Points information). 이것은 PAYCO 지갑 안의 일이고, Kunavo 잔액이 떨어졌을 때 자동으로 충전되게 하는 기능은 아닙니다(아래 ‘한도와 PAYCO만의 제약’ 참고).
- The minimum amount is unaffected. Stripe의 PAYCO 최소 결제 금액은 100원이라(Stripe PAYCO documentation), 최소 충전액 $10에는 걸리지 않습니다.
- Authentication. PAYCO 앱 소개에 따르면 결제 비밀번호 대신 Face ID를 쓸 수 있습니다(App Store PAYCO app information, October 3, 2026 확인).
We have not confirmed, based on Kunavo's payment screen, which sources (linked card or points) appear in the PAYCO payment window. Whether a card blocked from international payments is approved when linked to PAYCO may also depend on the card issuer's settings. If it is blocked, use the ‘domestic card’ option on the won payment screen.
How to top up Kunavo with PAYCO
You need the PAYCO app on your phone (payment password or Face ID), a card linked to PAYCO or preloaded PAYCO Points, and the minimum top-up of $10. Your Kunavo balance decreases only as used, with no monthly fee, remains available without an expiration date, and is not deducted for failed requests. Claude Haiku 4.5 for lighter tasks costs $0.70 per 1M input tokens, so $10 is sufficient for trying it for the first time.
1. Create an account
Create an account with a Google account or email on the sign-up page. Since PAYCO is selected when you top up, you do not need to open the PAYCO app at this stage.
2. Choose a tier based on the source you will use to pay with PAYCO
The top-up tiers on the Billing screen are $10, $100, $1,000, $5,000, and larger tiers receive bonuses ($100 충전 시 잔액 $110, $1,000 충전 시 잔액 $1,200, $5,000 충전 시 잔액 $6,250). The tiers are listed in dollars, but the amount compared with the PAYCO limit is the won amount on the next screen. If you plan to pay with PAYCO Points, choose from $10·$100·$1,000. $5,000 exceeds 2 million won in Korean won and can be paid only with a card linked to PAYCO. New accounts may have larger tiers locked until the first payment is confirmed, so for the first PAYCO payment it is faster to try $10.
3. Confirm that the payment screen is in Korean won (₩) and select PAYCO
버튼을 누르면 Stripe 결제 화면으로 넘어갑니다. Stripe는 결제하는 사람의 위치에 따라 금액을 현지 통화로 보여 주고(Stripe documentation), 한국에서 열면 원화 금액과 함께 PAYCO가 결제 수단 목록에 나옵니다. 같은 화면에 카카오페이·네이버페이·삼성페이·국내 카드, 카드와 Link, Safari·iPhone의 Apple Pay, Google Pay를 설정한 Chrome·안드로이드의 Google Pay도 있습니다. PAYCO는 Stripe에서 원화로만 결제되는 수단이라(Stripe PAYCO documentation), 금액이 달러로 보이면 PAYCO도 보이지 않습니다.
4. Authorize in PAYCO
PAYCO를 고르면 Stripe의 국내 처리 파트너 화면으로 넘어가 PAYCO로 결제를 인증·승인한 뒤 다시 돌아옵니다. Stripe의 PAYCO 문서는 이 거래가 NICEPAY를 통해 처리된다고 적고 있습니다(Stripe PAYCO documentation, October 3, 2026 확인). 로그인과 인증 방식, 고를 수 있는 재원은 PAYCO 쪽 화면을 따릅니다.
5. Return and reconcile the balance with your PAYCO payment history
After PAYCO authorization completes and you return to Kunavo, check the balance and top-up ledger on the Billing screen, and confirm that the same transaction appears in the PAYCO app's payment history. If the balance update is delayed, check by refreshing; do not authorize the payment again in PAYCO. Authorizing twice creates two top-ups.
6. Create a key and connect it to Claude Code
Create a key beginning with sk-kn- in API Keys. An example of testing the key with one line of curl is in Complete guide to paying for Claude. To run Claude Code using the balance topped up with PAYCO instead of a Pro or Max login, enter the Kunavo address and key and pin the model.
# 클로드 코드를 구독 로그인 대신 Kunavo 키로 실행하면 PAYCO로 충전한 잔액에서 차감됩니다.
export ANTHROPIC_BASE_URL=https://api.kunavo.com # /v1은 붙이지 않습니다
export ANTHROPIC_AUTH_TOKEN=sk-kn-...
# 기본 모델과 opus·sonnet 별칭이 Kunavo에 없는 최신 모델을 가리키지 않도록 고정합니다.
# sonnet 별칭은 그대로 두면 Kunavo에 없는 Sonnet 5.5를 요청해 /model sonnet이 404가 됩니다.
# opus 별칭은 Opus 5.5로 고정하며, 클로드 코드 v2.1.280 이상이 필요합니다(이전 버전은 claude update).

export ANTHROPIC_DEFAULT_OPUS_MODEL=claude-opus-5-5
export ANTHROPIC_DEFAULT_SONNET_MODEL=claude-sonnet-5
export ANTHROPIC_DEFAULT_HAIKU_MODEL=claude-haiku-4-5

Limits and PAYCO-specific restrictions
- One-time payments only—automatic top-up unavailable. Stripe Checkout은 PAYCO를 결제(payment) 모드에서만 지원하고, 결제 정보를 저장하는 설정(setup) 모드와 구독(subscription) 모드는 지원하지 않습니다(Stripe PAYCO documentation). Stripe의 한국 결제 수단 표도 PAYCO를 정기 결제 ‘아니요’로 적고 있습니다. 카카오페이·네이버페이가 ‘예’로 적힌 것과 다른 점입니다(Stripe Korean payment guidance, October 3, 2026 확인). 다른 결제대행사 Paddle의 문서도 PAYCO는 일회성 구매만 지원한다고 적고 있습니다(Paddle). Kunavo의 자동 충전은 애초에 저장한 카드나 Link로만 켤 수 있으니, PAYCO 충전은 잔액이 필요할 때마다 직접 합니다.
- PAYCO Points are limited to 2 million won. The $10·$100·$1,000 tier can be paid with points, but the won amount for the $5,000 tier exceeds 2 million won, so it cannot be paid using PAYCO Points alone. Pay with a card linked to PAYCO or use another payment method, such as a domestic or international-payment card.
- Linked cards are limited by the card limit. Stripe has no upper limit, but authorization may be declined if the card's limit or the card issuer's settings are exceeded.
- Because the payment is in won, it includes a currency-conversion fee. Kunavo의 요금과 충전 단계는 달러로 정해져 있고, Stripe가 보여 주는 원화 금액에는 2~4%의 환전 수수료가 들어 있습니다(Stripe Adaptive Pricing documentation, October 3, 2026 확인). 달러로 내면 이 수수료는 없지만 PAYCO는 선택지에서 사라집니다.
The absence of automatic top-up also means that calls stop with 402 insufficient_quota as soon as the balance reaches zero. If you run a long task with Claude Code, preload enough through PAYCO or save a separate card for automatic top-up.
When PAYCO is missing or payment fails
- PAYCO is not in the payment-method list. First check the currency symbol next to the amount. If it is $, the payment is not in won and the PAYCO button is not added. Stripe determines the currency from your access location, so turn off any overseas VPN and press the top-up button again on the Billing screen. If you selected $ manually, switch back to ₩ and PAYCO will reappear.
- PAYCO authentication was canceled or authorization failed. Stripe의 PAYCO 문서는 테스트 결제 설명에서, 승인이 실패한 결제가 완료되지 않고 새 결제 수단을 받는 상태(requires_payment_method)로 돌아간다고 적고 있습니다(Stripe PAYCO documentation, October 3, 2026 확인). 결제가 완료되지 않았다면 잔액은 충전되지 않으니, 같은 결제 화면에서 다른 수단을 고르거나 PAYCO로 한 번만 다시 시도하세요. 다시 시도하기 전에 결제(Billing) 화면에서 잔액이 이미 들어오지 않았는지 확인하세요. 짧은 시간에 결제를 여러 번 시도하면 Kunavo가 보안상 몇 시간 동안 새 충전을 받지 않습니다.
- The large amount was declined. If you paid with PAYCO Points, check the 2 million won limit; if you paid with a linked card, check the card limit. If this is before your first payment, start with a smaller tier.
- To use another payment method. 같은 원화 결제 화면에 카카오페이, Naver Pay, Samsung Pay(Stripe 기준 한 번에 2 million won까지, Stripe Samsung Pay documentation, October 3, 2026 확인), Domestic cards가 있고, 카드·Apple Pay·Google Pay·Link는 통화와 관계없이 쓸 수 있습니다. 네이버페이는 PAYCO와 달리 Stripe 한국 결제 수단 표에서 정기 결제 ‘예’로 적혀 있지만(Stripe Korean payment guidance), Kunavo의 자동 충전은 어느 간편결제와도 연결되지 않습니다. 수단을 한 표로 비교한 글은 Complete guide to Claude payment methods입니다.
- Methods Kunavo does not accept. Toss Pay, bank transfers, and mobile-phone payments are not available on Kunavo's payment screen.
Refunds and records
- Kunavo's policy. Amounts used for API calls are not refundable. Remaining balances do not expire; if you close the account, the balance is refunded to the original payment method, PAYCO, after payment fees are deducted (Terms of Use, Section 2). For other cases, such as duplicate top-ups, request a case-by-case review at support@kunavo.com; by default, we return the amount to your Kunavo balance, and we can issue a Stripe refund on request (billing documentation).
- Stripe's deadline and exchange rate. 한국 결제 수단으로 낸 결제는 결제일로부터 365일 안에만 환불할 수 있습니다(Stripe Korean payment guidance, October 3, 2026 확인). 원화로 낸 결제가 환불될 때는 원래 결제와 같은 환율이 적용됩니다(Stripe Adaptive Pricing documentation).
- Where it returns within PAYCO. We have not confirmed whether the refund returns to the linked card or to PAYCO Points, or how many days it takes; this depends on PAYCO's processing. Check the PAYCO app's payment history.
- Documentation. Kunavo does not issue tax invoices, cash receipts, or invoices. Top-up records remain in the ledger on the Billing screen, and payment records remain in the PAYCO app's payment history.
If you paid for an app subscription with PAYCO
iPhone 앱에서 PAYCO로 Claude 구독료를 냈다면 결제는 Apple과의 거래입니다. iPhone에서 낸 구독료는 Apple만 환불할 수 있고(Anthropic refund information, September 23, 2026 확인), Anthropic은 앱 구독에 청구서를 발급하지 않습니다(Pro / Max billing guide, September 23, 2026 확인). 구독과 API는 별개 상품이라 구독에는 API 사용이 들어 있지 않으므로(Anthropic guidance, September 23, 2026 확인), API나 API 키로 쓰는 클로드 코드는 위의 Kunavo 충전처럼 따로 결제합니다. 웹·앱 구독의 결제 수단과 Console 결제는 Complete guide to Claude payment methods에, 사용량 한도에 걸렸을 때의 선택지는 Claude Pro limit에 정리했습니다.
Claude Sonnet 5 costs $1.40 per 1M input tokens / $7.00 for output on Kunavo, and model-specific rates are listed in Claude API pricing. Which is cheaper, a subscription or the API, is covered in Claude Code pricing; how to use GPT with the same balance is covered in OpenAI API payment methods. To make your first top-up with PAYCO, sign up for Kunavo.
Frequently asked questions
Can you pay for Claude Pro with PAYCO?
Not on claude.ai's website. Anthropic says that subscriptions purchased on the web accept only credit or debit cards (Anthropic Billing FAQ, checked October 3, 2026). If you subscribe in the iPhone app, Apple processes the payment, and PAYCO appears in Apple's list of payment methods in Korea, so set PAYCO as your Apple account payment method (published August 6, 2026). On Android, Google Play lists PAYCO as a payment method for apps and digital content, but whether it can be used for recurring payments must be checked on the subscription payment screen.
Can you top up Claude API or Claude Code with PAYCO?
Yes, through Kunavo. When Kunavo's Stripe payment screen is displayed in Korean won (₩), PAYCO appears as a payment method, and you use that balance for Claude API and Claude Code run with an API key. Top up in advance from $10; there is no monthly fee, and balances do not expire. Anthropic's Claude Console is paid by card, so PAYCO cannot be used there.
Can you also pay for ChatGPT with PAYCO?
OpenAI says that Korean ChatGPT web subscriptions support KakaoPay, Naver Pay, and domestic cards; PAYCO is not on that list. API credits can be purchased only in dollars (OpenAI Help, checked October 3, 2026). App subscriptions follow Apple's or Google's payment-method lists. A balance topped up with PAYCO through Kunavo can be used for GPT API usage, but not to pay for ChatGPT Plus or OpenAI credits.
Can you enable automatic top-up with PAYCO?
No. Stripe supports PAYCO only for one-time payments; it does not support storing payment information for later charges. Kunavo's automatic top-up works only with a saved card or Link. With PAYCO, top up manually whenever you need more balance; if you need automatic top-up, save a card or Link separately.
Can you pay a large amount with PAYCO points?
Under Stripe's rules, the maximum balance that can be topped up to a PAYCO account is 2 million won. Among Kunavo's top-up tiers, $10·$100·$1,000 fits within that limit even after adding the currency-conversion fee, but $5,000 greatly exceeds 2 million won in Korean won and cannot be paid using PAYCO points alone. Cards linked to PAYCO have no maximum amount set by Stripe and are subject only to the card's own limit, so pay for large tiers with a linked card or a domestic or international-payment card.
PAYCO does not appear on the payment screen.
Stripe offers PAYCO only for payments in Korean won (KRW), so if the amount is shown with a $ sign, there is no PAYCO button. If you are using a VPN that changes your location to another country, turn it off and reopen the payment screen; if you selected $ directly on the payment screen, switch it back to ₩. If PAYCO still does not appear, use KakaoPay, Naver Pay, Samsung Pay, or a domestic card on the same won screen, or use a card, Apple Pay, Google Pay, or Link regardless of the currency. Kunavo does not accept Toss Pay.
Does paying with PAYCO incur a fee?
Kunavo's prices are set in dollars (USD), and the won amount displayed by Stripe on the payment screen includes a 2–4% currency-conversion fee (Stripe information, checked October 3, 2026). Paying in dollars avoids this fee, but PAYCO is available only for won payments and therefore disappears from the options. The won amount displayed is the amount charged through PAYCO.
Can a PAYCO top-up be refunded, or can I receive documentation?
Amounts used for API calls are not refundable. If you close the account, the remaining balance, after deducting payment fees, is returned to the original payment method—PAYCO. For other cases, such as duplicate top-ups, request a case-by-case review at support@kunavo.com; by default, we return the amount to your Kunavo balance, and we can issue a Stripe refund on request. Stripe says refunds for Korean payment methods can be processed only within 365 days of the payment date. Kunavo does not issue tax invoices, cash receipts, or invoices. Top-up records remain in the ledger on Kunavo's Billing screen and in the PAYCO app's payment history.
