How do I switch existing OpenAI SDK code to the Model API?

Most Chat Completions code moves with four changes:

1. Base URL: https://api.gateway.clatterlabs.xyz/v1
2. Key: a Clatter Labs clsk_ key with models:invoke
3. Header: X-Clatter-Account: CL-... as a default header
4. Model: supercosmos-flash, supercosmos-max or supercosmos-heavy

client = OpenAI(
    base_url="https://api.gateway.clatterlabs.xyz/v1",
    api_key=os.environ["CLATTER_API_KEY"],
    default_headers={"X-Clatter-Account": os.environ["CLATTER_ACCOUNT_ID"]},
)
