1. Python Script to Download & Rotate Wallpapers

Automate daily desktop wallpaper changes or Discord bot image delivery in Python using requests:

import requests
import os
import random

API_KEY = "YOUR_NEXWALL_API_KEY"
BASE_URL = "https://nexwall.kodnextech.com/api/developer/v1"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Accept": "application/json"
}

def get_random_4k_wallpaper(category_id=None):
    params = {"per_page": 50}
    if category_id:
        params["category_id"] = category_id
        
    response = requests.get(f"{BASE_URL}/wallpapers", headers=headers, params=params)
    if response.status_code == 200:
        data = response.json().get("data", [])
        if data:
            chosen = random.choice(data)
            print(f"Selected: ID {chosen['id']} - Resolution: {chosen.get('resolution')}")
            return chosen["image_url"]
    return None

def download_wallpaper(image_url, save_path="daily_wallpaper.webp"):
    img_data = requests.get(image_url).content
    with open(save_path, "wb") as f:
        f.write(img_data)
    print(f"Successfully downloaded 4K wallpaper to {save_path}")

if __name__ == "__main__":
    url = get_random_4k_wallpaper()
    if url:
        download_wallpaper(url)
