  3. Create your sk-tch-… key in the dashboard.
from openai import OpenAI

client = OpenAI(
    base_url="https://tchavi.com/api/v1",
    api_key="sk-tch-...",
)

response = client.chat.completions.create(

    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)

The sk-tch-… key is a Tchavi key, not a Google key.

Gemini API questions
