response = client.chat.completions.create(
    model="sonar",
    messages=[
        {"role": "system", "content": "Be precise and concise."},
        {"role": "user", "content": "How many stars are in the Milky Way?"}
    ]
)
print(response)

• Customizable Filters: Allows restricting searches to specific domains or timeframes (e.g., the past month).
