OpenAI (platform.openai.com) and Anthropic (console.anthropic.com) bill API usage by card only. If your bank card is declined abroad or your funds are in stablecoins, there are two common routes: an API gateway/reseller, or a prepaid card you attach to your own account.
Option 1: API gateway or reseller
Gateways accept crypto and give you their own API key that proxies requests to OpenAI or Anthropic. Setup is quick, but your traffic and prompts pass through a third party, prices usually carry a markup, and you do not get your own organization, usage dashboard or official invoices.
Option 2: prepaid card on your own account
You keep a normal OpenAI / Anthropic organization with your own keys, rate limits and invoices, and pay the credits with a prepaid virtual card funded in USDT or USDC. Pink Card works this way: no sign-up, card details emailed in 5–10 minutes.
- Buy a Pink Card at pinkcard.cc/en with USDT or USDC (presets from $110, custom from $100).
- In platform.openai.com → Settings → Billing, or console.anthropic.com → Billing, add the card.
- Buy credits. Keep about 20% more on the card than the credit amount: providers add tax for your billing region, and the card takes $1 per transaction.
- Only enable auto-recharge if the card balance covers it; repeated failed auto-charges make the account more likely to decline future cards.
- Reload the same card when it runs low — the number stays the same.
