# Making requests

You can paste the command below into your terminal to run your first API request. Make sure to replace `$OXYGEN_API_KEY` with your secret API key.

```bash
curl https://app.oxyapi.uk/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OXYGEN_API_KEY" \
  -d '{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "Say this is a test!"}],
     "temperature": 0.7
   }'

```

This request queries the `gpt-3.5-turbo` model (which under the hood points to the **latest** `gpt-3.5-turbo` **model variant**) to complete the text starting with a prompt of "*Say this is a test*". You should get a response back that resembles the following:

```json
{
    "id": "chatcmpl-abc123",
    "object": "chat.completion",
    "created": 1677858242,
    "model": "gpt-3.5-turbo-1106",
    "usage": {
        "prompt_tokens": 13,
        "completion_tokens": 7,
        "total_tokens": 20
    },
    "choices": [
        {
            "message": {
                "role": "assistant",
                "content": "\n\nThis is a test!"
            },
            "logprobs": null,
            "finish_reason": "stop",
            "index": 0
        }
    ]
}
```

Now that you've generated your first chat completion, let's break down the response object. We can see the `finish_reason` is `stop` which means the API returned the full chat completion generated by the model without running into any limits. In the choices list, we only generated a single message but you can set the `n` parameter to generate multiple messages choices.
