How to Pay for LLM APIs with USDT (No Overseas Credit Card)

## The problem

Plenty of developers can write the code but cannot pay for the API. Official providers often require a credit card from a supported country, and many cards get declined. That blocks real projects before they even start.

## The fix: stablecoin top-ups

ClaudeN AI lets you top up your balance with USDT. You send stablecoins, your balance updates, and you spend it across Claude, GPT and Gemini at per-token rates. No subscription, no card, no region lock on payment.

## Step by step

1. Create an account and verify your email.
2. Open the top-up page and choose a USDT amount.
3. Send to the displayed address on the supported chain.
4. Your balance credits automatically after confirmation.
5. Create an API key and start calling models.

``bash
curl https://clauden.ai/v1/chat/completions \
-H "Authorization: Bearer YOUR_CLAUDEN_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"gpt-4o","messages":[{"role":"user","content":"Hello!"}]}'
``

## Keeping costs predictable

Because you pre-fund a balance, you never get a surprise invoice. You can watch usage in your dashboard and top up only when you need more. For individual developers and side projects, that predictability is often worth more than a marginal price difference.
