from openai import OpenAI

client = OpenAI(
    api_key=os.environ["TOKENAIR_API_KEY"],
    base_url=os.environ["TOKENAIR_BASE_URL"],
)

completion = client.chat.completions.create(
    model="gpt-5-mini",
    messages=[
        {"role": "system", "content": "You write concise implementation notes."},
        {"role": "user", "content": "Give me a three-step API migration checklist."},
    ],
)

print(completion.choices[0].message.content)

Run the file from a server-side Python environment. A successful response prints the assistant message. Keep the API key in your process environment or secret manager, not in the Python file.
