Everyone pays the list price. Reaching Elite (hold or stake 1,337 $XAVA, or hold 1,337,000 $XINF) unlocks the Elite price and a bigger buyback of your token. How it works

openai sdk (python)
from openai import OpenAI

client = OpenAI(
    base_url="https://zinf.ai/v1",
    api_key="xk_live_...",  # your Xava Inference key
)

r = client.chat.completions.create(
    model="openai/gpt-5.4-nano",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(r.choices[0].message.content)
