Here's an example of how to make a basic API call using Python's requests library:

```python

import requests

YOUR_API_KEY = "your_api_key_here"

model = "sonar-medium-online"

messages = [{"role": "user", "content": "Hello"}]

headers = {"Authorization": f"Bearer {YOUR_API_KEY}", "Content-Type": "application/json"}

response = requests.post(

"https://openrouter.ai/api/v1/chat/completions",

headers=headers,

json={"model": model, "messages": messages},

)

```

Note that you'll need to replace `YOUR_API_KEY` with your actual API key and specify the model and messages as needed for your application.
