# Introduction

> Routeway is a unified, OpenAI-compatible API gateway providing access to 200+ LLMs and image models.

Routeway is an API gateway that enables you to integrate and switch between 200+ AI models (including GPT-5.5, Claude Opus 4.8, Kimi K2.7, DeepSeek V4, Grok 4, and Gemini 3.1 Pro) using a single, unified, OpenAI-compatible API.

Because it is fully compatible with OpenAI, migrating your existing applications takes only a few minutes. See the [Migration Guide](/getting-started/migration) for step-by-step instructions.

Instead of managing multiple SDKs, credentials, and billing accounts, you only need one client configuration and one API key.

## Base URL

All API requests are routed through:

```http theme={null}
https://api.routeway.ai/v1
```

## Quick Example (cURL)

Test your connection with a standard Chat Completions request:

```bash theme={null}
curl https://api.routeway.ai/v1/chat/completions \
  -H "Authorization: Bearer $ROUTEWAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "kimi-k2.7-code",
    "messages": [
      {"role": "user", "content": "Say hello!"}
    ]
  }'
```
