API Reference

OneAI provides an OpenAI-compatible API. If you already use the OpenAI SDK, just change base_url and api_key — everything else works identically.

All API requests require an API key. Get yours from the dashboard.

# Option 1: Environment variable
export ONEAI_API_KEY="oneai-sk-your-key-here"

# Option 2: Pass directly in code
import openai
client = openai.OpenAI(
    api_key="oneai-sk-your-key-here",
    base_url="https://api.oneai.io/v1"
)

Send a conversation and get a model response.

from openai import OpenAI

client = OpenAI(
    api_key="oneai-sk-...",
    base_url="https://api.oneai.io/v1"
)

response = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Explain quantum computing in simple terms."}
    ],
    temperature=0.7,
    max_tokens=1024
)

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

Parameters

Stream responses token-by-token for real-time output.

stream = client.chat.completions.create(
    model="deepseek-v3",
    messages=[{"role": "user", "content": "Write a haiku about AI"}],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
