If your credit card gets declined by OpenAI or Anthropic — a common issue in Russia, Iran, Turkey, MENA, Vietnam, Indonesia, and Latin America — you are not alone. Vynex API solves this by accepting USDT (TRC20/ERC20) crypto payments alongside wire transfer and cards.
One OpenAI-compatible endpoint. GPT, Claude, Gemini, DeepSeek, Qwen, and GLM-5.2 from a single key. Pay with USDT — no foreign card, no VPN, no reseller markup. Hong Kong company, commercial invoice available for B2B.

Yes. Since payments are via USDT (crypto), there is no region block. The API endpoint is accessible globally. This makes Vynex ideal for developers in Russia, Iran, Turkey, and other regions where OpenAI/Anthropic reject local cards.
USDT on TRC20 (Tron) has very low fees (~$1). Vynex is a Hong Kong registered company. For B2B clients, wire transfer with commercial invoice is also available.
