Quickstart

Before using AsteroidRouter, you must generate an API key to authenticate your HTTP requests.

1. Go to the AsteroidRouter Console and log in or register.
2. Navigate to the API Keys section from the sidebar navigation.
3. Click the Generate API Key button to create a new token.
4. Copy the token values immediately (starts with sk-ar-...). For security reasons, the console will not show this token again.

To route requests through AsteroidRouter, redirect the baseURL parameter in your OpenAI SDK (or custom client) to our endpoint:

You can verify your connection to the AsteroidRouter infrastructure instantly by firing a basic curl chat-completions request from your terminal:

curl https://inference-api.asteroidrouter.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ASTEROIDROUTER_API_KEY" \
  -d '{
    "model": "gpt-5",
    "messages": [{"role": "user", "content": "Ping"}]
  }'

A successful connection returns a standard OpenAI-formatted JSON object containing the response text:

{
  "id": "chatcmpl-ast888",
  "object": "chat.completion",
  "created": 1785502900,
  "model": "gpt-5",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Pong!"
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 8,
    "completion_tokens": 2,
    "total_tokens": 10
  }
}
