from anthropic import Anthropic

client = Anthropic(
    api_key="sk-cptc-your-key",
    base_url=""
)

message = client.messages.create(
    model="claude-sonnet-4-5-20250929",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello!"}
    ]
)

print(message.content[0].text)
