How to Use the Add Watermark API Endpoint

The `/api/add_watermark` endpoint allows you to overlay a watermark image onto a video with configurable parameters. You can specify the position and scale of the watermark, giving you flexibility in how your final product looks.

Here are the parameters you need to use this API:

1. **video_url** (required): The URL of the video you want to watermark.

2. **watermark_url** (required): The URL of the watermark image.

3. **position** (optional): The placement of the watermark, defaulting to 'bottom-right'.

import requests

url = 'https://www.ffmpegapi.net/api/add_watermark'
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer YOUR_API_KEY'}
payload = {
    'video_url': 'https://example.com/video.mp4',
    'watermark_url': 'https://example.com/logo.png',
    'position': 'bottom-right',
    'scale': 0.2
}
response = requests.post(url, json=payload, headers=headers)
print(response.json())
