CometAPI uses the OpenAI SDK format — change only base_url and api_key: 
import openai

client = openai.OpenAI(
    api_key="<COMETAPI_KEY>",
    base_url="https://api.cometapi.com/v1"
)

response = client.chat.completions.create(
    model="<MODEL_ID>",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)
Already using the OpenAI SDK? Only base_url and api_key need to change — your existing application code works without modification.
