Python SDK Guide

Real200 is fully compatible with the OpenAI Python SDK. Just modify the base_url to integrate.

Installation

pip install openai

Requires Python 3.8+.

Basic Usage

from openai import OpenAI

client = OpenAI(
    api_key="sk-real200-xxxxxxxxxxxxxxxx",  # Your Real200 API Key
    base_url="https://real200.com/v1"       # Real200 gateway address
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello, please introduce Real200."}],
    temperature=0.7,
    max_tokens=200
)

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

Environment Variable Configuration

import os
from openai import OpenAI

os.environ["OPENAI_API_KEY"] = "sk-real200-xxx"
os.environ["OPENAI_BASE_URL"] = "https://real200.com/v1"

# Client automatically reads environment variables
client = OpenAI()

Streaming Response

stream = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Write a poem about AI."}],
    stream=True
)

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

Function Calling

import json

tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get weather information for a specified city",
            "parameters": {
                "type": "object",
                "properties": {
                    "city": {"type": "string", "description": "City name"}
                },
                "required": ["city"]
            }
        }
    }
]

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "What is the weather in Beijing?"}],
    tools=tools,
    tool_choice="auto"
)

if response.choices[0].message.tool_calls:
    for tool_call in response.choices[0].message.tool_calls:
        args = json.loads(tool_call.function.arguments)
        print(f"Calling {tool_call.function.name}, args: {args}")

Error Handling

from openai import OpenAI, APIError, RateLimitError, AuthenticationError

try:
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[{"role": "user", "content": "Hello"}]
    )
except AuthenticationError as e:
    print("Authentication failed, please check API Key:", e)
except RateLimitError as e:
    print("Rate limit exceeded, please wait and retry:", e)
except APIError as e:
    print("API error:", e)
