The Challenge
Developers juggling multiple AI providers face a maze of API keys, billing dashboards, and rate limits.
Managing separate credentials, billing, and rate limits for every AI provider slows down development.
Premium model costs add up fast, with no easy way to mix in cheaper or free models for simple tasks.
Token pricing varies wildly by provider, making it hard to estimate spend before you build.
Committing to one AI provider format makes switching models later a rewrite, not a config change.
A single provider outage or rate limit can take your whole product down with no fallback in place.
Testing GPT-4 against Claude or Gemini for the same task means rewriting integration code each time.
The Solution
One gateway, every major model, transparent token-based pricing.
Full SSE streaming passthrough for real-time token-by-token responses, just like calling the provider directly.
Route to free open-source models like Llama and DeepSeek, or premium models like GPT-4 and Claude.
A single OpenAI-compatible endpoint routes your requests to the right model automatically.
Top up your balance with USDT and pay only for the tokens you actually use — no subscriptions.
See exactly what every request costs before you send it. No hidden markups.
Track spend, requests, and model usage across your whole account from one dashboard.
