Python Integration Steps

Install Required Libraries

pip install requests

Example Code Walkthrough

import requests

API_KEY = "YOUR_API_KEY"
URL = "https://wisdom-gate.juheapi.com/v1/chat/completions"
headers = {
    "Authorization": API_KEY,
    "Content-Type": "application/json",
    "Accept": "*/*",
    "Host": "wisdom-gate.juheapi.com",
    "Connection": "keep-alive"
}

payload = {
    "model": "wisdom-ai-claude-sonnet-4",
    "messages": [{"role": "user", "content": "Hello, how can you help me today?"}]
}

response = requests.post(URL, headers=headers, json=payload)
print(response.json())

Steps:

1. Install requests.
2. Add your API key in headers.
3. Send POST request with model and messages.

Node.js Integration Steps

Install Required Packages

npm install axios

Example Code Walkthrough

const axios = require('axios');

const API_KEY = "YOUR_API_KEY";
const URL = "https://wisdom-gate.juheapi.com/v1/chat/completions";

axios.post(URL, {
    model: "wisdom-ai-claude-sonnet-4",
    messages: [{ role: "user", content: "Hello, how can you help me today?" }]
}, {
    headers: {
        'Authorization': API_KEY,
        'Content-Type': 'application/json',
        'Accept': '*/*',
        'Host': 'wisdom-gate.juheapi.com',
        'Connection': 'keep-alive'
    }
}).then(res => {
    console.log(res.data);
}).catch(err => {
    console.error(err);
});

Steps:

1. Install axios.
2. Configure headers with your API key.
3. POST request with the model and message payload.
