# Quickstart: Chat Completions

> Minimal OpenRouter-style MyRouter call.

Use a MyRouter API key with the OpenRouter-style chat completions endpoint.

```bash theme={null}
curl https://api.myrouter.example/api/v1/chat/completions \
  -H "Authorization: Bearer $MYROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "your-model-id",
    "messages": [
      { "role": "user", "content": "Hello" }
    ]
  }'
```

The runtime request is executed by the platform LLM Gateway. Product-owned APIs handle key lifecycle, prepaid credits, checkout, usage, costs, balance transactions, invoices, activity, and generation metadata.
