Quick Start

NexusAPI is fully compatible with the OpenAI API format. Simply change the base URL to start using China's AI models.

1. Install the SDK

pip install openai

2. Configure your client

from openai import OpenAI

client = OpenAI(
    api_key="your_nexus_api_key",
    base_url="https://www.xouliwei.com/v1"
)

3. Make your first request

response = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

Authentication

All API requests require authentication using an API key. Include your API key in the Authorization header.

Authorization: Bearer your_nexus_api_key

Note: Keep your API key secure. Do not share it in public repositories or client-side code.

Chat Completions

The Chat Completions API follows the OpenAI format. Here are examples in different languages:

Python

from openai import OpenAI

client = OpenAI(
    api_key="your_nexus_api_key",
    base_url="https://www.xouliwei.com/v1"
)

# Chat completion
response = client.chat.completions.create(
    model="gpt-4",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Hello!"}
    ]
)

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

JavaScript/Node.js

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'your_nexus_api_key',
  baseURL: 'https://www.xouliwei.com/v1'
});

// Chat completion
const response = await client.chat.completions.create({
  model: 'gpt-4',
  messages: [
    { role: 'system', content: 'You are a helpful assistant.' },
    { role: 'user', content: 'Hello!' }
  ]
});

console.log(response.choices[0].message.content);
