Why a single gateway
Instead of juggling three billing accounts, three API keys, and three credit-card checkouts, ClaudeN gives you one gateway to Claude, GPT and Gemini. One balance, one OpenAI-compatible endpoint, and one USDT top-up cover every model — so you can benchmark, switch, or mix providers without rewriting your integration or exposing your card.
Frequently asked questions
Which model is cheapest?
Gemini 1.5 Pro is generally the lowest-cost option for very large inputs, while Claude 3.5 Sonnet and GPT-4o sit in a similar moderate range. Because you pay per token from a single balance, you can send each request to whichever model is cheapest for that task without any minimums or monthly fees.
Can I use one API key for all models?
Yes. One ClaudeN API key works across Claude, GPT and Gemini through an OpenAI-compatible endpoint. Just change the model name in your request to switch providers — no new keys, accounts, or code changes required.
Do I need a credit card?
No credit card is required. You can top up your balance with USDT and start calling any supported model immediately, which is ideal for teams and regions where card-based billing is difficult.
