Keep your client, swap the URL

An OpenAI-compatible /v1 endpoint — your existing chat client talks to Vorden agents with a one-line change.

python
from openai import OpenAI client = OpenAI(    base_url="https://api.vorden.ai/v1",  # the only change    api_key=VORDEN_API_KEY,) reply = client.chat.completions.create(    model="vorden-agent:support",    messages=[{"role": "user", "content": "Where is my order?"}],)
