Request example

Replace $XHUO_API_KEY with a token from the console. The base URL is https://api.xhuoapi.ai/v1; existing OpenAI SDK code only needs that one change.

curl https://api.xhuoapi.ai/v1/chat/completions \
  -H "Authorization: Bearer $XHUO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-5.4", "messages": [{"role": "user", "content": "Hello"}]}'

from openai import OpenAI

client = OpenAI(base_url="https://api.xhuoapi.ai/v1", api_key="YOUR_XHUOAPI_KEY")
resp = client.chat.completions.create(
    model="gpt-5.4",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)
