# What is IoTeX AI Gateway

> A unified AI model interface service for accessing multiple mainstream AI models through a single API

IoTeX AI Gateway is a unified AI model interface service that allows you to access multiple mainstream AI models — including Gemini, DeepSeek, Llama, Qwen, and more — through a single OpenAI-compatible API.

No need to register with individual AI providers. One endpoint, one API key — access every supported model instantly.

## How It Works

1. You send a request to `https://gateway.iotex.ai/v1/chat/completions` using any OpenAI-compatible client
2. IoTeX AI Gateway routes your request to the specified model provider
3. The response is returned in the standard OpenAI format

```bash theme={null}
curl https://gateway.iotex.ai/v1/chat/completions \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"model": "gemini-2.5-flash", "messages": [{"role": "user", "content": "Hello!"}]}'
```

## Affordable Pricing

Enjoy up to **20% off** on various models compared to official provider pricing. No hidden fees, no subscriptions — pay only for what you use.
