OpenAI-Compatible API

Use the official OpenAI Python/Node.js SDK:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.sixfinger.live/v1",
    api_key="sixfinger_xxx"
)

response = client.chat.completions.create(
    model="gpt-5",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

Streaming:

from openai import OpenAI

client = OpenAI(base_url="https://api.sixfinger.live/v1", api_key="sixfinger_xxx")

for chunk in client.chat.completions.create(
    model="claude-haiku-4-5",
    messages=[{"role": "user", "content": "Tell me a story"}],
    stream=True
):
    content = chunk.choices[0].delta.content
    if content:
        print(content, end="", flush=True)
