GPT API proxy — OpenAI models, one key

Call OpenAI GPT through a proxy with a prepaid balance. Pay with USDT or PayPal, use one key, and skip the direct OpenAI account.

ClaudeN AI is a GPT API proxy that lets you reach OpenAI GPT models without a direct OpenAI account. You fund a prepaid balance with USDT or PayPal and call GPT through an OpenAI-compatible endpoint at https://clauden.ai/v1. Because it is a unified gateway, the same key also reaches Claude and Gemini, so one integration and balance covers GPT alongside other leading models.

Why use a GPT proxy

No OpenAI account

Reach GPT models without opening or verifying a direct OpenAI account.

Prepaid, no card

Fund with USDT or PayPal and pay per token — no credit card on file, no monthly minimum.

Same OpenAI SDK

It speaks the OpenAI format natively, so your existing code works with a new base URL and key.

Claude & Gemini too

The same key also reaches Claude and Gemini for easy benchmarking and failover.
