Same code as the OpenAI SDK — change the base URL and key, pick a model id:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.airforce/v1",
    api_key="YOUR_KEY",
)

resp = client.chat.completions.create(
    model="gemini-2.5-pro",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)
